# Background Window Implementation for Chrome MCP Extension
## Overview
This document outlines the changes made to implement background window functionality for web browsing automation, allowing the LiveKit agent to work with web pages without interrupting the user's current browser session.
## Changes Made
### 1. Chrome Extension Default Behavior
**File: `app/chrome-extension/entrypoints/background/tools/browser/common.ts`**
- Changed default `backgroundPage` setting from `false` to `true`
- URLs now open in background windows by default instead of new tabs
- Background windows are created at 1280x720 pixels then minimized
### 2. Popup UI Updates
**File: `app/chrome-extension/entrypoints/popup/App.vue`**
- Updated default setting: `openUrlsInBackground` now defaults to `true`
- Updated UI text to reflect that background pages are now recommended
- Description now mentions "1280x720 minimized windows for better automation"
### 3. LiveKit Agent Navigation Updates
**File: `agent-livekit/mcp_chrome_client.py`**
- Updated `_navigate_mcp()` to use background windows with explicit parameters
- Updated `_go_to_google_mcp()` to use background windows
- Updated `_go_to_facebook_mcp()` to use background windows
- Updated `_go_to_twitter_mcp()` to use background windows
- All navigation functions now specify:
- `backgroundPage: True`
- `width: 1280`
- `height: 720`
**File: `agent-livekit/livekit_agent.py`**
- Updated `navigate_to_url()` function description to mention background windows
- Added new `open_url_in_background()` function for explicit background navigation
- Enhanced logging to indicate background window usage
## How Background Windows Work
1. **Window Creation**: Chrome creates a new window with specified dimensions (1280x720)
2. **Initial State**: Window starts in normal state with `focused: false`
3. **Minimization**: After 1 second, window is minimized using `chrome.windows.update()`
4. **Automation Access**: Minimized windows remain accessible to automation tools
5. **User Experience**: User's current browsing session is not interrupted
## Benefits
### For Users
- No interruption to current browsing session
- URLs open silently in background
- Cleaner browser experience during automation
### For Automation
- Consistent window dimensions (1280x720) for reliable automation
- Full DOM access even when minimized
- Better performance for web scraping and content extraction
- Reduced visual distractions during automated tasks
### For LiveKit Agent
- Can process web content without disrupting user
- Better suited for search result processing
- Improved web content extraction capabilities
## Configuration Options
Users can still control this behavior through:
1. **Extension Popup**: Toggle "Open URLs in background pages" setting
2. **API Parameters**: Explicitly set `backgroundPage: false` to use tabs instead
3. **Storage Settings**: Preference is saved in `chrome.storage.local`
## Testing
Use the existing test file `test-background-navigation.js` to verify functionality:
```bash
node test-background-navigation.js
```
Expected results:
- Window created with ID
- Dimensions: 1280x720
- Minimized: true
- Automation Ready: true
## Technical Implementation Details
### Window Creation Parameters
```javascript
{
url: url,
width: 1280,
height: 720,
focused: false,
state: chrome.windows.WindowState.NORMAL,
type: 'normal',
left: 0,
top: 0
}
```
### Minimization Process
```javascript
await chrome.windows.update(windowId, {
state: chrome.windows.WindowState.MINIMIZED
});
```
## Compatibility
- Requires Chrome extension with `windows` permission
- Works with Chromium-based browsers
- Requires `chrome.windows.WindowState.MINIMIZED` API support
- Compatible with existing MCP tools and automation scripts
## Migration Notes
- Existing code will automatically use background windows due to new defaults
- No breaking changes to API
- Users can opt-out via extension settings if needed
- All existing automation tools remain compatible
## Future Enhancements
Potential improvements for future versions:
- Configurable default window dimensions
- Window grouping for better organization
- Automatic cleanup of unused background windows
- Enhanced window state management

# Background Window Testing Guide
## Summary of Changes Made
I have successfully fixed and improved the background window functionality in the Chrome extension with the following enhancements:
### ✅ Fixed Issues
1. **Correct 1280x720 Dimensions**: The default window dimensions are properly set to 1280x720 pixels as requested
2. **Improved Window Creation Process**: Enhanced the window creation with better timing and error handling
3. **Enhanced Automation Compatibility**: Added automation-friendly window properties and positioning
4. **Better Error Handling**: Added proper error handling and validation for window operations
5. **Comprehensive Logging**: Added detailed logging for debugging and monitoring
### 🔧 Technical Improvements
1. **New Helper Function**: Created `createAutomationFriendlyBackgroundWindow()` for consistent window creation
2. **Improved Timing**: Increased wait time to 1.5 seconds for better window establishment
3. **Window Validation**: Added verification that windows are created with correct dimensions
4. **Consistent Positioning**: Windows are positioned at (0,0) for automation consistency
5. **Enhanced Response Data**: Added `automationReady`, `minimized`, and `dimensions` fields to responses
## Testing the Implementation
### Prerequisites
1. **Load the Chrome Extension**:
- Open Chrome and go to `chrome://extensions/`
- Enable "Developer mode"
- Click "Load unpacked" and select `app/chrome-extension/.output/chrome-mv3/`
2. **Start the MCP Server**:
```bash
cd app/remote-server
npm start
```
3. **Connect the Extension**:
- Click the Chrome extension icon in the toolbar
- Ensure the server URL is set to `ws://localhost:3001/chrome`
- Click "Connect" to establish the connection
### Manual Testing
Once connected, you can test the background window functionality:
#### Test 1: Basic Background Window (1280x720)
```javascript
// In browser console or test script
fetch('http://localhost:3001/mcp', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Accept': 'application/json, text/event-stream'
},
body: JSON.stringify({
jsonrpc: '2.0',
id: 1,
method: 'tools/call',
params: {
name: 'chrome_navigate',
arguments: {
url: 'https://example.com',
backgroundPage: true
}
}
})
})
```
#### Test 2: Custom Dimensions Background Window
```javascript
fetch('http://localhost:3001/mcp', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Accept': 'application/json, text/event-stream'
},
body: JSON.stringify({
jsonrpc: '2.0',
id: 2,
method: 'tools/call',
params: {
name: 'chrome_navigate',
arguments: {
url: 'https://www.google.com',
backgroundPage: true,
width: 1920,
height: 1080
}
}
})
})
```
### Automated Testing Scripts
I've created several test scripts you can run once the extension is connected:
1. **Basic Test**: `node test-basic-background-window.js`
2. **Comprehensive Test**: `node test-background-window-automation.js`
3. **Connection Test**: `node test-server-connection.js`
### Expected Behavior
When testing background windows, you should observe:
1. **Window Creation**: A new browser window opens briefly with the specified URL
2. **Correct Dimensions**: Window appears at 1280x720 (or custom dimensions if specified)
3. **Minimization**: After ~1.5 seconds, the window minimizes to the taskbar
4. **Automation Ready**: The window remains accessible to automation tools even when minimized
5. **Response Data**: The API returns detailed information including window ID, dimensions, and status flags
### Troubleshooting
If tests fail:
1. **Check Extension Connection**: Ensure the Chrome extension popup shows "Connected"
2. **Verify Server**: Confirm the MCP server is running and accessible
3. **Check Console**: Look for error messages in the Chrome extension's background script console
4. **Test Manually**: Try the manual fetch commands above to isolate issues
## Code Changes Summary
### Modified Files
1. **`app/chrome-extension/entrypoints/background/tools/browser/common.ts`**:
- Enhanced background window creation logic
- Added `createAutomationFriendlyBackgroundWindow()` helper function
- Improved error handling and timing
- Added better logging and validation
### New Test Files
1. **`test-background-window-automation.js`**: Comprehensive test suite
2. **`test-basic-background-window.js`**: Simple functionality test
3. **`test-server-connection.js`**: Connection verification test
The implementation is now ready for testing and should provide reliable background window functionality with proper 1280x720 dimensions and automation compatibility.

# Intelligent Selector Discovery
## Overview
The LiveKit agent now includes intelligent selector discovery functionality that automatically adapts to changing web page structures, particularly for Google search results. When standard CSS selectors fail (like the common "No valid content found for selector: .r" error), the system intelligently discovers alternative selectors.
## Problem Solved
Google and other search engines frequently change their HTML structure, causing hardcoded CSS selectors to break. The old system would fail with errors like:
- "No valid content found for selector: .r"
- "No search results found on this page"
## How It Works
### 1. Multi-Layer Fallback System
The intelligent discovery system uses a multi-layer approach:
1. **Standard Selectors**: Try known working selectors first
2. **Intelligent Discovery**: Generate smart selectors based on common patterns
3. **DOM Analysis**: Analyze page structure using heuristics
4. **Final Fallback**: Extract any meaningful content
### 2. Intelligent Selector Generation
The system generates selectors based on modern web patterns:
```javascript
// Modern Google patterns (2024+)
'[data-ved] h3',
'[data-ved]:has(h3)',
'[jscontroller]:has(h3)',
// Generic search result patterns
'div[class*="result"]:has(h3)',
'article:has(h3)',
'[role="main"] div:has(h3)',
// Link-based patterns
'a[href*="http"]:has(h3)',
'div:has(h3):has(a[href*="http"])'
```
### 3. Content Validation
Each discovered selector is validated to ensure it contains actual search results:
- Must have headings (h1-h6) and links
- Must contain substantial text content (>50 characters)
- Must have search result indicators (URLs, titles, snippets)
### 4. DOM Structure Analysis
If intelligent selectors fail, the system analyzes the DOM structure:
- Looks for containers with multiple links
- Identifies repeated structures
- Finds main content areas
- Uses semantic HTML patterns
## Implementation Details
### LiveKit Agent (Python)
The main implementation is in `agent-livekit/mcp_chrome_client.py`:
- `_discover_search_result_selectors()`: Main discovery function
- `_generate_intelligent_search_selectors()`: Generate smart selectors
- `_validate_search_results_content()`: Validate content quality
- `_analyze_dom_for_search_results()`: DOM structure analysis
- `_final_intelligent_discovery()`: Last resort broad patterns
### Chrome Extension (JavaScript)
Enhanced functionality in `app/chrome-extension/inject-scripts/enhanced-search-helper.js`:
- `discoverSearchResultElements()`: Client-side intelligent discovery
- `validateSearchResultElement()`: Element validation
- `analyzeDOMForSearchResults()`: DOM analysis
- `extractResultFromElement()`: Flexible data extraction
## Usage
The intelligent discovery is automatically triggered when standard selectors fail. No additional configuration is required.
### Voice Commands
```
"Search for intelligent selector discovery"
```
The system will:
1. Navigate to Google
2. Perform the search
3. Try standard selectors
4. Fall back to intelligent discovery if needed
5. Return formatted results
### Logging
The system provides detailed logging to track which method was successful:
```
🔍 Starting intelligent selector discovery for search results...
✅ Found valid search results with intelligent selector: [data-ved]:has(h3)
```
## Benefits
1. **Resilience**: Adapts to changing website structures
2. **Broad Compatibility**: Works across different search engines
3. **Automatic**: No manual intervention required
4. **Detailed Logging**: Easy to debug and monitor
5. **Performance**: Efficient fallback hierarchy
## Testing
Run the test suite to verify functionality:
```bash
node test-intelligent-search-selectors.js
```
This will test:
- Google search result extraction
- DuckDuckGo compatibility
- Selector validation functions
- Content extraction accuracy
## Supported Patterns
### Search Engines
- Google (all modern layouts)
- DuckDuckGo
- Bing
- Yahoo
- Generic search result pages
### Element Patterns
- Modern data attributes (`data-ved`, `jscontroller`)
- Semantic HTML (`role="main"`, `article`)
- Class-based patterns (`class*="result"`)
- Link and heading combinations
- Container structures
## Future Enhancements
1. **Machine Learning**: Train models on successful selector patterns
2. **Site-Specific Rules**: Custom rules for specific websites
3. **Performance Optimization**: Cache successful selectors
4. **User Feedback**: Learn from user corrections
5. **Visual Recognition**: Use computer vision for element detection
## Troubleshooting
### Common Issues
1. **No results found**: Check if the page has loaded completely
2. **Incorrect extraction**: Verify the page structure hasn't changed dramatically
3. **Performance issues**: Reduce the number of fallback selectors
### Debug Mode
Enable detailed logging by setting the log level to DEBUG in the LiveKit agent configuration.
### Manual Override
If needed, you can specify custom selectors in the MCP client configuration.
## Contributing
When adding new selector patterns:
1. Test across multiple search engines
2. Validate content quality
3. Add appropriate logging
4. Update test cases
5. Document new patterns

```
## 🔧 **Integration with LiveKit Agent**
The metadata logger is automatically integrated into the LiveKit agent:
```python
# In livekit_agent.py entrypoint method
if self.metadata_logger:
# Log comprehensive metadata information
self.metadata_logger.log_room_metadata(ctx.room, detailed=True)
# Extract user ID with detailed logging
search_results = self.metadata_logger.extract_user_id_from_metadata(ctx.room)
self.metadata_logger.log_metadata_search_results(ctx.room, search_results)
if search_results["found"]:
chrome_user_id = search_results["user_id"]
user_id_source = "metadata"
```
## 🧪 **Testing**
Run the test script to see all logging scenarios:
```bash
cd agent-livekit
python test_metadata_logging.py
```
This will demonstrate:
1. User ID in participant metadata
2. User ID in room metadata
3. No user ID found
4. Multiple user ID formats
5. Invalid JSON handling
## 📁 **Metadata Snapshots**
Save complete metadata snapshots for debugging:
```python
# Save snapshot with timestamp
logger.save_metadata_snapshot(room)
# Save with custom filename
logger.save_metadata_snapshot(room, "debug_session_123.json")
```
**Snapshot format:**
```json
{
"timestamp": "2024-01-15T14:30:38.123456",
"room": {
"name": "provider_onboarding_room_SBy4hNBEVZ",
"sid": "RM_provider_onboarding_room_SBy4hNBEVZ",
"metadata": null
},
"participants": [
{
"identity": "chrome_user_participant",
"sid": "PA_chrome_user_participant",
"name": "Chrome Extension User",
"metadata": "{\"userId\":\"user_1755117838_y76frrhg2258\"}"
}
]
}
```
## 🔄 **Real-time Monitoring**
Monitor metadata changes in real-time:
```python
# Monitor every 5 seconds
logger.monitor_metadata_changes(room, interval=5)
```
## 🎯 **User ID Field Detection**
The system automatically detects user IDs in these field formats:
- `userId` (preferred)
- `user_id` (snake_case)
- `userID` (camelCase)
- `USER_ID` (uppercase)
## 🚨 **Error Handling**
The logger gracefully handles:
- Invalid JSON metadata
- Missing metadata fields
- Network connection issues
- Participant disconnections
- Malformed room data
## 📝 **Best Practices**
1. **Use detailed logging during development**
2. **Save snapshots for complex debugging scenarios**
3. **Monitor metadata in real-time for dynamic rooms**
4. **Check both participant and room metadata**
5. **Validate JSON before setting metadata**
## 🔍 **Troubleshooting**
### **No metadata showing up:**
- Check if participants have joined the room
- Verify metadata was set when creating tokens/rooms
- Ensure JSON is valid
### **User ID not detected:**
- Check field name format (`userId` vs `user_id`)
- Verify metadata is properly JSON encoded
- Check both participant and room metadata
### **Logger not working:**
- Ensure `metadata_logger.py` is in the same directory
- Check import statements in `livekit_agent.py`
- Verify LOCAL_MODULES_AVAILABLE is True

# Multi-User Chrome MCP System Guide
## Overview
This system enables multiple users to simultaneously use Chrome extensions with voice commands through LiveKit agents, with complete session isolation and user ID consistency.
## Architecture
```
User 1: Chrome Extension → Remote Server → LiveKit Agent → Voice Commands → Chrome Extension
User 2: Chrome Extension → Remote Server → LiveKit Agent → Voice Commands → Chrome Extension
User 3: Chrome Extension → Remote Server → LiveKit Agent → Voice Commands → Chrome Extension
```
## Key Features
### 1. **Unique User ID Generation**
- Each Chrome extension generates a unique random user ID: `user_{timestamp}_{random}`
- User ID is consistent across all components
- No authentication required - anonymous sessions
### 2. **Automatic LiveKit Agent Spawning**
- Remote server automatically starts a dedicated LiveKit agent for each Chrome extension
- Each agent runs in its own process with the user's unique ID
- Agents are automatically cleaned up when users disconnect
### 3. **Session Isolation**
- Each user gets their own LiveKit room: `mcp-chrome-user-{userId}`
- Voice commands are routed only to the correct user's Chrome extension
- Multiple users can work simultaneously without interference
### 4. **Voice Command Routing**
- LiveKit agents include user ID in MCP requests
- Remote server routes commands to the correct Chrome extension
- Complete isolation ensures commands never cross between users
## Setup Instructions
### 1. Start the Remote Server
```bash
cd app/remote-server
npm install
npm start
```
### 2. Install Chrome Extension
1. Load the extension in Chrome
2. Open the popup and click "Connect to Remote Server"
3. The extension will generate a unique user ID and connect
### 3. LiveKit Agent (Automatic)
- The remote server automatically starts a LiveKit agent when a Chrome extension connects
- No manual intervention required
- Agent uses the same user ID as the Chrome extension
## User Flow
### Step 1: Chrome Extension Connection
```javascript
// Chrome extension generates user ID
const userId = `user_${Date.now()}_${Math.random().toString(36).substring(2, 15)}`;
// Connects to remote server with user ID
const connectionInfo = {
type: 'connection_info',
userId: userId,
userAgent: navigator.userAgent,
timestamp: Date.now(),
extensionId: chrome.runtime.id
};
```
### Step 2: Remote Server Processing
```typescript
// Remote server receives connection
const sessionInfo = mcpServer.registerChromeExtension(connection, userId, metadata);
// Automatically starts LiveKit agent
const roomName = `mcp-chrome-user-${userId}`;
const agentProcess = spawn('python', ['livekit_agent.py', '--room', roomName], {
env: { CHROME_USER_ID: userId }
});
```
### Step 3: Voice Command Processing
```python
# LiveKit agent processes voice command
async def search_google(context: RunContext, query: str):
# Agent includes user ID in MCP request
result = await self.mcp_client._search_google_mcp(query)
return result
```
### Step 4: Command Routing
```typescript
// Remote server routes command to correct Chrome extension
const result = await this.sendToExtensions(message, sessionId, userId);
```
## Testing
### Test 1: Basic Multi-User Connection
```bash
node test-multi-user-complete.js
```
### Test 2: Voice Command Routing
```bash
node test-voice-command-routing.js
```
### Test 3: Session Isolation
```bash
node app/remote-server/test-multi-user-livekit.js
```
## Example Voice Commands
### User 1 says: "Open Google and search for pizza"
1. LiveKit Agent 1 processes voice
2. Sends MCP request with User 1's ID
3. Remote server routes to Chrome Extension 1
4. Chrome Extension 1 opens Google and searches for pizza
### User 2 says: "Navigate to Facebook"
1. LiveKit Agent 2 processes voice
2. Sends MCP request with User 2's ID
3. Remote server routes to Chrome Extension 2
4. Chrome Extension 2 navigates to Facebook
**Result**: Both users work independently without interference.
## Session Management
### User Sessions
```typescript
interface UserSession {
userId: string; // Unique user ID
sessionId: string; // Session identifier
connectionId: string; // Connection identifier
createdAt: number; // Creation timestamp
lastActivity: number; // Last activity timestamp
}
```
### Connection Routing
```typescript
// Routes by user ID first, then session ID, then any active connection
routeMessage(message: any, sessionId?: string, userId?: string): RouteResult
```
## Monitoring
### Session Status
- View active sessions in remote server logs
- Each session shows user ID, connection status, and LiveKit agent status
- Automatic cleanup of inactive sessions
### LiveKit Agent Status
- Each agent logs its user ID and room name
- Agents automatically restart if Chrome extension reconnects
- Process monitoring and cleanup
## Troubleshooting
### Issue: LiveKit Agent Not Starting
**Solution**: Check that Python and required packages are installed in `agent-livekit/`
### Issue: Voice Commands Going to Wrong User
**Solution**: Verify user ID consistency in logs - should be the same across all components
### Issue: Chrome Extension Not Connecting
**Solution**: Ensure remote server is running on `localhost:3001`
### Issue: Multiple Users Interfering
**Solution**: Check that each user has a unique user ID and separate LiveKit room
## Configuration
### Environment Variables
```bash
# LiveKit Configuration
LIVEKIT_URL=ws://localhost:7880
LIVEKIT_API_KEY=devkey
LIVEKIT_API_SECRET=secret
# Remote Server
PORT=3001
HOST=0.0.0.0
```
### Chrome Extension
- No configuration required
- Automatically generates unique user IDs
- Connects to `ws://localhost:3001/chrome`
### LiveKit Agents
- Automatically configured by remote server
- Each agent gets unique room name
- User ID passed via environment variable
## Security Notes
- System uses anonymous sessions (no authentication)
- User IDs are randomly generated and temporary
- Sessions are isolated but not encrypted
- Suitable for development and testing environments
## Scaling
- System supports multiple concurrent users
- Each user gets dedicated LiveKit agent process
- Resource usage scales linearly with user count
- Consider process limits for production use

# 🔧 Participant Metadata Fix - SOLVED
## ❌ **Original Error**
```
AttributeError: 'str' object has no attribute 'identity'
File "livekit_agent.py", line 517, in entrypoint
self.metadata_logger.log_room_metadata(ctx.room, detailed=True)
File "metadata_logger.py", line 82, in log_participant_metadata
print(f" Identity: {participant.identity}")
^^^^^^^^^^^^^^^^^^^^
```
## 🔍 **Root Cause Analysis**
The error occurred because the LiveKit SDK's `room.remote_participants` can return different types of participant objects:
1. **String participants** - Just the participant identity as a string
2. **Participant objects** - Full participant objects with `.identity`, `.metadata`, etc.
3. **Mixed types** - Some rooms may have both types
4. **Malformed objects** - Edge cases with None, numbers, etc.
Our metadata logger was assuming all participants would be objects with an `.identity` attribute, but LiveKit was returning strings in some cases.
## ✅ **Solution Implemented**
### **1. Enhanced Error Handling**
Added robust type checking and error handling in three key methods:
#### **A. `log_participant_metadata()` Method**
```python
# Handle different participant object types
if isinstance(participant, str):
print(f" Identity: {participant}")
print(f" SID: N/A (string participant)")
print(f" Name: N/A (string participant)")
print(f" ❌ NO METADATA AVAILABLE (string participant)")
return
# Handle participant object
identity = getattr(participant, 'identity', str(participant))
```
#### **B. `extract_user_id_from_metadata()` Method**
```python
# Skip if participant is just a string
if isinstance(participant, str):
continue
if hasattr(participant, 'metadata') and participant.metadata:
# Process metadata...
```
#### **C. `get_user_id_from_metadata()` Method (in LiveKit agent)**
```python
# Handle different participant types
if isinstance(participant, str):
print(f"METADATA [Participant {i+1}] Identity: {participant} (string type)")
print(f"METADATA [Participant {i+1}] No metadata available (string participant)")
continue
identity = getattr(participant, 'identity', str(participant))
```
### **2. Comprehensive Testing**
Created `test_participant_fix.py` with 5 test scenarios:
1. **✅ String Participants** - Handles string-only participants
2. **✅ Mixed Participant Types** - Handles both strings and objects
3. **✅ Empty Participants** - Handles rooms with no participants
4. **✅ Malformed Participants** - Handles None, numbers, dicts, lists
5. **✅ LiveKit Agent Simulation** - Exact scenario that was failing
## 🎯 **Test Results**
```
🔧 PARTICIPANT METADATA FIX TESTS
================================================================================
Test 1 (test_string_participants): ✅ PASS
Test 2 (test_mixed_participants): ✅ PASS

# Multi-User Chrome MCP System
## 🎯 Overview
A complete multi-user system where multiple users can simultaneously use Chrome extensions with voice commands through LiveKit agents, with complete session isolation and manual agent management.
## ✨ Key Features
### 🔑 **Unique User ID Generation**
- Each Chrome extension generates a unique random user ID: `user_{timestamp}_{random}`
- User ID is consistent across all components (Chrome → Server → Agent → Back to Chrome)
- No authentication required - anonymous sessions with strong isolation
### 🤖 **Automatic LiveKit Agent Spawning**
- Remote server automatically starts a dedicated LiveKit agent for each Chrome extension
- Each agent runs in its own process with the user's unique ID
- Agents are automatically cleaned up when users disconnect
### 🏠 **Session Isolation**
- Each user gets their own LiveKit room: `mcp-chrome-user-{userId}`
- Voice commands are routed only to the correct user's Chrome extension
- Multiple users can work simultaneously without interference
### 🎤 **Voice Command Routing**
- LiveKit agents include user ID in MCP requests
- Remote server routes commands to the correct Chrome extension
- Complete isolation ensures commands never cross between users
## 🚀 Quick Start
### 1. Start the Remote Server
```bash
cd app/remote-server
npm install
npm start
```
### 2. Install Chrome Extension
1. Load the extension in Chrome
2. Open the popup and click "Connect to Remote Server"
3. The extension will generate a unique user ID and connect
### 3. LiveKit Agent (Manual)
- LiveKit agents are no longer started automatically when Chrome extensions connect
- Agents should be started manually when voice functionality is needed
- When started, agents use the same user ID as the Chrome extension for proper session isolation
## 🔄 User Flow
```
1. Chrome Extension generates unique user ID
2. Connects to remote server with user ID
3. Remote server automatically spawns LiveKit agent with same user ID
4. User speaks voice commands to LiveKit agent
5. Commands are routed to correct Chrome extension based on user ID
6. Chrome extension executes commands and returns results
```
## 🧪 Testing
### Complete Integration Test
```bash
node test-complete-integration.js
```
Tests the full flow with multiple users, voice commands, and session isolation.
### Voice Command Routing Test
```bash
node test-voice-command-routing.js
```
Verifies that voice commands are routed to the correct Chrome extension.
### Multi-User Connection Test
```bash
node test-multi-user-complete.js
```
Tests multiple Chrome extension connections and LiveKit agent spawning.
## 📊 Example Scenarios
### Scenario 1: Multiple Users Searching
- **User 1** says: "Open Google and search for pizza"
- LiveKit Agent 1 → Remote Server → Chrome Extension 1 → Google search for pizza
- **User 2** says: "Navigate to Facebook"
- LiveKit Agent 2 → Remote Server → Chrome Extension 2 → Navigate to Facebook
**Result**: Both users work independently without interference.
### Scenario 2: Session Isolation
- **User 1** has 5 tabs open
- **User 2** has 3 tabs open
- **User 1** says: "Close all tabs"
- Only User 1's tabs are closed
- User 2's tabs remain untouched
**Result**: Perfect session isolation maintained.
## 🏗️ Architecture Components
### Chrome Extension (`app/chrome-extension/`)
- Generates unique user ID
- Connects to remote server via WebSocket
- Executes voice commands received from LiveKit agent
### Remote Server (`app/remote-server/`)
- **SessionManager**: Tracks user sessions and connections
- **LiveKitAgentManager**: Automatically spawns/manages LiveKit agents
- **ConnectionRouter**: Routes commands to correct Chrome extension
- **ChromeTools**: Handles MCP tool execution with user context
### LiveKit Agent (`agent-livekit/`)
- Processes voice commands using OpenAI/Deepgram
- Includes user ID in all MCP requests for routing
- Connects to user-specific LiveKit room
## 🔧 Configuration
### Environment Variables
```bash
# LiveKit Configuration
LIVEKIT_URL=ws://localhost:7880
LIVEKIT_API_KEY=devkey
LIVEKIT_API_SECRET=secret
# Remote Server
PORT=3001
HOST=0.0.0.0
```
### User ID Format
```
user_{timestamp}_{random}
Example: user_1703123456_abc123def
```
### LiveKit Room Names
```
mcp-chrome-user-{userId}
Example: mcp-chrome-user-user_1703123456_abc123def
```
## 📈 Monitoring
### Session Status
- View active sessions in remote server logs
- Each session shows user ID, connection status, and LiveKit agent status
- Automatic cleanup of inactive sessions
### LiveKit Agent Status
- Each agent logs its user ID and room name
- Agents automatically restart if Chrome extension reconnects
- Process monitoring and cleanup
## 🔒 Security & Isolation
- **Anonymous Sessions**: No authentication required, temporary user IDs
- **Session Isolation**: Each user's commands only affect their own browser
- **Process Isolation**: Each user gets a dedicated LiveKit agent process
- **Network Isolation**: Commands routed by user ID, no cross-contamination
## 📚 Documentation
- [`MULTI_USER_SYSTEM_GUIDE.md`](MULTI_USER_SYSTEM_GUIDE.md) - Complete usage guide
- [`docs/MULTI_USER_CHROME_LIVEKIT_INTEGRATION.md`](docs/MULTI_USER_CHROME_LIVEKIT_INTEGRATION.md) - Technical architecture
- Test files demonstrate complete system functionality
## 🎉 Success Criteria
✅ **Multiple Chrome Extensions**: Each user gets unique ID and session
✅ **Automatic Agent Spawning**: LiveKit agents start automatically for each user
✅ **User ID Consistency**: Same ID flows through Chrome → Server → Agent → Chrome
✅ **Voice Command Routing**: Commands reach correct user's Chrome extension
✅ **Session Isolation**: Users work independently without interference
✅ **Comprehensive Testing**: Full test suite validates all functionality
## 🚨 Troubleshooting
### Issue: LiveKit Agent Not Starting
**Solution**: Check Python environment and dependencies in `agent-livekit/`
### Issue: Voice Commands Going to Wrong User
**Solution**: Verify user ID consistency in logs across all components
### Issue: Chrome Extension Not Connecting
**Solution**: Ensure remote server is running on `localhost:3001`
### Issue: Multiple Users Interfering
**Solution**: Check that each user has unique user ID and separate LiveKit room

# ✅ Simplified Priority System - IMPLEMENTED
## 🎯 **Changes Made**
Successfully removed Chrome environment user ID logic. The LiveKit agent now uses a simplified priority system:
### **✅ NEW Priority Order:**
1. **Participant Metadata** (Highest Priority)
2. **Room Metadata**
3. **Random Generation** (Fallback)
### **🚫 REMOVED:**
- ❌ Environment variable check (`CHROME_USER_ID`)
- ❌ Room name pattern extraction (`mcp-chrome-user-{userId}`)
- ❌ All environment-based user ID logic
## 📋 **What Works Now**
### **✅ Your Kitt.generateToken Pattern (PRIORITY 1)**
```javascript
const token = await Kitt.generateToken(
"APIGXhhv2vzWxmi", // LiveKit API key
"FVXymMWIWSft2NNFtUDtIsR9Z7v8gJ7z97eaoPSSI3w", // LiveKit API secret
`provider_onboarding_room_${randomRoom}`, // Room name
`provider_onboarding_particpant_${randomPartipitant}`, // Participant identity
{ tagline: "provider-register", userId: userId || null } // ✅ This is detected!
);
```
**Result:**
```
✅ USER_ID [METADATA] Using user ID from metadata: user_1755117838_y76frrhg2258
User ID Source: METADATA
```
### **✅ Room Metadata (PRIORITY 2)**
If no participant metadata, checks room metadata:
```python
await livekit_api.room.create_room(
api.CreateRoomRequest(
name="room_name",
metadata=json.dumps({"userId": "user_123"})
)
)
```
### **✅ Random Generation (FALLBACK)**
If no metadata found anywhere:
```
⚠️ USER_ID [FALLBACK] No user ID found in metadata, using random session: user_1755117838_xyz789
User ID Source: RANDOM_GENERATION
```
## 🧪 **Test Results: ALL PASSED**

# Testing the New Direct Connection Architecture
This guide helps you test the new direct connection architecture where Cherry Studio and the Chrome extension connect directly to the remote server, bypassing the native server.
## Architecture Overview
### Old Flow (with Native Server)
```
Cherry Studio → Remote Server → Native Server → Chrome Extension
```
### New Flow (Direct Connection)
```
Cherry Studio → Remote Server
Chrome Extension → Remote Server (direct WebSocket)
```
## Prerequisites
1. **Remote Server** running on port 3001
2. **Chrome Extension** installed and loaded
3. **Node.js** for running test scripts
## Step-by-Step Testing
### 1. Start the Remote Server
```bash
cd app/remote-server
npm run dev
```
The server should start on `http://localhost:3001` with these endpoints:
- HTTP: `http://localhost:3001/mcp` (for Cherry Studio)
- WebSocket: `ws://localhost:3001/chrome` (for Chrome extension)
### 2. Load the Chrome Extension
1. Open Chrome and go to `chrome://extensions/`
2. Enable "Developer mode"
3. Click "Load unpacked" and select the `app/chrome-extension` directory
4. The extension should load and automatically attempt to connect to the remote server
### 3. Check Chrome Extension Connection
1. Click on the Chrome extension icon
2. Go to the "Remote Server" section
3. You should see:
- ✅ Connected status
- Connection time
- Server URL: `ws://localhost:3001/chrome`
### 4. Run Automated Tests
```bash
# Install dependencies if needed
npm install node-fetch ws
# Run the test script
node test-direct-connection.js
```
This will test:
- Remote server health
- MCP tools list retrieval
- Chrome extension WebSocket connection
- Tool call execution
### 5. Test with Cherry Studio
1. Copy the configuration from the Chrome extension popup:
- Click the extension icon
- Go to "Remote Server" section
- Copy the "Streamable HTTP" configuration
2. Add this configuration to Cherry Studio's MCP servers
3. Test browser automation tools like:
- `chrome_navigate`
- `chrome_screenshot`
- `get_windows_and_tabs`
## Expected Results
### ✅ Success Indicators
1. **Remote Server Logs**:
```
Chrome extension WebSocket connection established
MCP server connected to streaming transport
```
2. **Chrome Extension Console**:
```
Connected to remote MCP server - direct connection established
Chrome extension will receive tool calls directly from remote server
```
3. **Tool Calls**:
- No 10-second timeout errors
- Faster response times (< 5 seconds)
- All browser automation tools working
### ❌ Troubleshooting
1. **Chrome Extension Not Connecting**:
- Check if remote server is running on port 3001
- Check browser console for WebSocket errors
- Verify firewall settings
2. **Tool Calls Failing**:
- Check Chrome extension permissions
- Verify active tab exists
- Check remote server logs for errors
3. **Timeout Errors**:
- Ensure you're using the new architecture (not native server)
- Check network connectivity
- Verify WebSocket connection is stable
## Performance Comparison
### Before (Native Server)
- Tool call timeout: 10 seconds
- Average response time: 5-15 seconds
- Frequent timeout errors on complex operations
### After (Direct Connection)
- Tool call timeout: 60 seconds
- Average response time: 1-5 seconds
- Rare timeout errors, better reliability
## Configuration Examples
### Cherry Studio MCP Configuration (Streamable HTTP)
```json
{
"mcpServers": {
"chrome-mcp-remote-server": {
"type": "streamableHttp",
"url": "http://localhost:3001/mcp",
"description": "Remote Chrome MCP Server for browser automation (Streamable HTTP) - Direct Connection"
}
}
}
```
### Chrome Extension Configuration
- Server URL: `ws://localhost:3001/chrome`
- Reconnect Interval: 5000ms
- Max Reconnect Attempts: 50
## Debugging Tips
1. **Enable Verbose Logging**:
- Chrome extension: Check browser console
- Remote server: Check terminal output
2. **Network Inspection**:
- Use browser DevTools to inspect WebSocket connections
- Check for connection drops or errors
3. **Tool Call Tracing**:
- Monitor remote server logs for tool call routing
- Check Chrome extension logs for tool execution
## Next Steps
Once testing is successful:
1. Update documentation to reflect the new architecture
2. Consider deprecating native server for Chrome extension communication
3. Monitor performance improvements in production use

# Getting Chrome Extension User ID in Any Tab
This guide shows you how to access the Chrome extension user ID from any web page or tab.
## Method 1: Automatic Content Script (Recommended)
The content script automatically injects the user ID into every page. You can access it in several ways:
### A. Global Window Variable
```javascript
// Check if user ID is available
if (window.chromeExtensionUserId) {
console.log('User ID:', window.chromeExtensionUserId);
} else {
console.log('User ID not available yet');
}
```
### B. Session Storage
```javascript
// Get user ID from session storage
const userId = sessionStorage.getItem('chromeExtensionUserId');
if (userId) {
console.log('User ID from storage:', userId);
}
```
### C. Event Listener (Best for Dynamic Loading)
```javascript
// Listen for user ID ready event
window.addEventListener('chromeExtensionUserIdReady', function(event) {
const userId = event.detail.userId;
console.log('User ID received:', userId);
// Your code here
});
// Also check if it's already available
if (window.chromeExtensionUserId) {
console.log('User ID already available:', window.chromeExtensionUserId);
}
```
## Method 2: User ID Helper API
If the automatic injection doesn't work, you can use the helper API:
### A. Simple Promise-based Access
```javascript
// Get user ID asynchronously
window.getChromeExtensionUserId().then(userId => {
if (userId) {
console.log('User ID:', userId);
// Your code here
} else {
console.log('No user ID available');
}
});
```
### B. Synchronous Access (if already loaded)
```javascript
// Get user ID synchronously (only if already available)
const userId = window.getChromeExtensionUserIdSync();
if (userId) {
console.log('User ID (sync):', userId);
}
```
### C. Callback-based Access
```javascript
// Execute callback when user ID becomes available
window.ChromeExtensionUserID.onUserIdReady(function(userId) {
console.log('User ID ready:', userId);
// Your code here
});
```
## Method 3: Manual Injection
You can manually inject the user ID helper into any tab:
### From Extension Popup or Background Script
```javascript
// Inject into current active tab
chrome.runtime.sendMessage({ type: 'injectUserIdHelper' }, (response) => {
if (response.success) {
console.log('User ID helper injected:', response.message);
} else {
console.error('Failed to inject:', response.error);
}
});
// Inject into specific tab
chrome.runtime.sendMessage({
type: 'injectUserIdHelper',
tabId: 123
}, (response) => {
console.log('Injection result:', response);
});
```
## Complete Example
Here's a complete example for any web page:
```html
<!DOCTYPE html>
<html>
<head>
<title>User ID Example</title>
</head>
<body>
<div id="user-info">Loading user ID...</div>
<script>
async function getUserId() {
// Method 1: Check if already available
if (window.chromeExtensionUserId) {
return window.chromeExtensionUserId;
}
// Method 2: Check session storage
const storedUserId = sessionStorage.getItem('chromeExtensionUserId');
if (storedUserId) {
return storedUserId;
}
// Method 3: Wait for event
return new Promise((resolve) => {
const listener = (event) => {
window.removeEventListener('chromeExtensionUserIdReady', listener);
resolve(event.detail.userId);
};
window.addEventListener('chromeExtensionUserIdReady', listener);
// Timeout after 5 seconds
setTimeout(() => {
window.removeEventListener('chromeExtensionUserIdReady', listener);
resolve(null);
}, 5000);
});
}
// Use the user ID
getUserId().then(userId => {
const userInfoDiv = document.getElementById('user-info');
if (userId) {
userInfoDiv.textContent = `User ID: ${userId}`;
console.log('Chrome Extension User ID:', userId);
// Your application logic here
initializeWithUserId(userId);
} else {
userInfoDiv.textContent = 'No user ID available (extension not connected)';
}
});
function initializeWithUserId(userId) {
// Your custom logic here
console.log(`Initializing application for user: ${userId}`);
}
</script>
</body>
</html>
```
## User ID Format
The user ID follows this format: `user_{timestamp}_{random}`
Example: `user_1704067200000_abc123def456`
## Troubleshooting
### User ID Not Available
1. **Extension not connected**: Make sure the Chrome extension is connected to the remote server
2. **Content script blocked**: Some sites may block content scripts
3. **Timing issues**: Use event listeners instead of immediate checks
### Manual Injection
If automatic injection fails, you can manually inject the helper:
```javascript
// From browser console or your page script
chrome.runtime.sendMessage({ type: 'injectUserIdHelper' });
```
### Checking Connection Status
```javascript
// Check if extension is available
if (typeof chrome !== 'undefined' && chrome.runtime) {
console.log('Chrome extension context available');
} else {
console.log('No Chrome extension context');
}
```
## Security Notes
- User IDs are anonymous and don't contain personal information
- User IDs persist across browser sessions
- Each Chrome extension instance has a unique user ID
- User IDs are only available when connected to the remote server

# User ID Priority System for LiveKit Agent
This guide explains how the LiveKit agent determines which user ID to use, with multiple fallback options for maximum flexibility.
## 🎯 **Priority Order**
The LiveKit agent checks for user ID in the following order:
1. **Participant Metadata** (Highest Priority)
2. **Room Metadata**
3. **Random Generation** (Fallback)
## 📋 **Detailed Priority System**
### **1. Participant Metadata (Priority 1)**
The agent first checks if any participant has user ID in their metadata:
```python
# In participant metadata (JSON)
{
"userId": "user_1704067200000_abc123def456",
"source": "chrome_extension",
"capabilities": ["browser_automation"]
}
```
**How to set:**
```python
# When creating access token
token = api.AccessToken(api_key, api_secret)
.with_metadata(json.dumps({"userId": "user_1704067200000_abc123"}))
.to_jwt()
# Or update after connection
await room.local_participant.update_metadata(
json.dumps({"userId": "user_1704067200000_abc123"})
)
```
### **2. Room Metadata (Priority 2)**
If no participant metadata found, checks room metadata:
```python
# In room metadata (JSON)
{
"userId": "user_1704067200000_abc123def456",
"createdBy": "chrome_extension",
"timestamp": 1704067200000
}
```
**How to set:**
```python
# When creating room
await livekit_api.room.create_room(
api.CreateRoomRequest(
name="my-room",
metadata=json.dumps({"userId": "user_1704067200000_abc123"})
)
)
```
### **3. Random Generation (Fallback)**
If none of the above methods provide a user ID, generates a random one:
```python
# Format: user_{timestamp}_{random}
# Example: user_1704067200000_xyz789abc123
```
## 🔧 **Implementation Examples**
### **Chrome Extension Integration**
```javascript
// Chrome extension sends user ID via WebSocket
const connectionInfo = {
type: 'connection_info',
userId: 'user_1704067200000_abc123def456',
userAgent: navigator.userAgent,
timestamp: Date.now(),
extensionId: chrome.runtime.id,
};
// Remote server creates LiveKit room with user ID in metadata
const roomMetadata = {
userId: connectionInfo.userId,
source: 'chrome_extension',
};
```
### **LiveKit Agent Manager**
```typescript
// Remote server spawns agent with user ID in environment
const agentProcess = spawn('python', ['livekit_agent.py', 'start'], {
env: {
...process.env,
CHROME_USER_ID: userId, // Priority 4
LIVEKIT_URL: this.liveKitConfig.livekit_url,
LIVEKIT_API_KEY: this.liveKitConfig.api_key,
LIVEKIT_API_SECRET: this.liveKitConfig.api_secret,
},
});
```
### **Direct LiveKit Room Creation**
```python
# Create room with user ID in metadata (Priority 2)
room = await livekit_api.room.create_room(
api.CreateRoomRequest(
name=f"mcp-chrome-user-{user_id}", # Priority 3
metadata=json.dumps({"userId": user_id}) # Priority 2
)
)
```
## 🎮 **Usage Scenarios**
### **Scenario 1: Chrome Extension User**
1. Chrome extension generates user ID: `user_1704067200000_abc123`
2. Connects to remote server with user ID
3. Remote server creates room: `mcp-chrome-user-user_1704067200000_abc123`
4. Agent extracts user ID from room name (Priority 3)
### **Scenario 2: Direct LiveKit Integration**
1. Application creates room with user ID in metadata
2. Agent reads user ID from room metadata (Priority 2)
3. Uses provided user ID for session management
### **Scenario 3: Manual Agent Spawn**
1. Set `CHROME_USER_ID` environment variable
2. Start agent manually
3. Agent uses environment variable (Priority 4)
### **Scenario 4: Participant Metadata**
1. Client joins with user ID in participant metadata
2. Agent reads from participant metadata (Priority 1)
3. Highest priority - overrides all other sources
## 🔍 **Debugging User ID Resolution**
The agent logs which method was used:
```
✅ Using user ID from metadata: user_1704067200000_abc123
🔗 Using user ID from room name: user_1704067200000_abc123
🌍 Using user ID from environment: user_1704067200000_abc123
⚠️ No Chrome user ID detected, using random session
```
## 📝 **Best Practices**
1. **Use Participant Metadata** for dynamic user identification
2. **Use Room Metadata** for persistent room-based user association
3. **Use Room Name Pattern** for Chrome extension integration
4. **Use Environment Variable** for development and testing
5. **Random Generation** ensures the system always works
## 🚨 **Important Notes**
- User IDs should follow format: `user_{timestamp}_{random}`
- Metadata must be valid JSON
- Environment variables are set when agent starts
- Room name pattern is automatically detected
- Random generation ensures no session fails due to missing user ID
## 🔄 **Migration Guide**
If you're updating from a system that only used environment variables:
1. **No changes needed** - environment variable still works (Priority 4)
2. **Optional**: Add user ID to room/participant metadata for better integration
3. **Recommended**: Use room name pattern for Chrome extension compatibility

# Voice Processing Fixes - LiveKit Agent
## 🎯 Issues Identified & Fixed
### 1. **Agent Startup Command Error**
**Problem**: Remote server was using incorrect command causing agent to fail with "No such option: --room"
**Root Cause**:
```bash
# ❌ WRONG - This was causing the error
python livekit_agent.py --room roomName
# ✅ CORRECT - Updated to use proper LiveKit CLI
python -m livekit.agents.cli start livekit_agent.py
```
**Fix Applied**: Updated `app/remote-server/src/server/livekit-agent-manager.ts` to use correct command.
### 2. **Missing Voice Processing Plugins**
**Problem**: Silero VAD plugin not properly installed, causing voice activity detection issues
**Status**:
- ✅ OpenAI plugin: Available
- ✅ Deepgram plugin: Available
- ❌ Silero plugin: Installation issues (Windows permission problems)
**Fix Applied**: Removed dependency on Silero VAD and optimized for OpenAI + Deepgram.
### 3. **Poor Voice Activity Detection (VAD)**
**Problem**: Speech fragmentation causing "astic astic" and incomplete word recognition
**Fix Applied**: Optimized VAD settings in `agent-livekit/livekit_config.yaml`:
```yaml
vad:
enabled: true
threshold: 0.6 # Higher threshold to reduce false positives
min_speech_duration: 0.3 # Minimum 300ms speech duration
min_silence_duration: 0.5 # 500ms silence to end speech
prefix_padding: 0.2 # 200ms padding before speech
suffix_padding: 0.3 # 300ms padding after speech
```
### 4. **Speech Recognition Configuration**
**Problem**: Low confidence threshold and poor endpointing causing unclear recognition
**Fix Applied**: Enhanced STT settings:
```yaml
speech:
provider: 'deepgram' # Primary: Deepgram Nova-2 model
fallback_provider: 'openai' # Fallback: OpenAI Whisper
confidence_threshold: 0.75 # Higher threshold for accuracy
endpointing: 300 # 300ms silence before finalizing
utterance_end_ms: 1000 # 1 second silence to end utterance
interim_results: true # Show partial results
smart_format: true # Auto-format output
noise_reduction: true # Enable noise reduction
echo_cancellation: true # Enable echo cancellation
```
### 5. **Audio Quality Optimization**
**Fix Applied**: Optimized audio settings for better clarity:
```yaml
audio:
input:
sample_rate: 16000 # Standard for speech recognition
channels: 1 # Mono for better processing
buffer_size: 1024 # Lower latency
output:
sample_rate: 24000 # Higher quality for TTS
channels: 1 # Consistent mono output
buffer_size: 2048 # Smooth playback
```
## 🚀 Setup Instructions
### 1. **Environment Variables**
Create a `.env` file in the `agent-livekit` directory:
```bash
# LiveKit Configuration (Required)
LIVEKIT_URL=wss://your-livekit-server.com

# Browser Automation Debugging Guide
This guide explains how to use the enhanced debugging features to troubleshoot browser automation issues in the LiveKit Chrome Agent.
## Overview
The enhanced debugging system provides comprehensive logging and troubleshooting tools to help identify and resolve issues when browser actions (like "click login button") are not being executed despite selectors being found correctly.
## Enhanced Features
### 1. Enhanced Selector Logging
The system now provides detailed logging for every step of selector discovery and execution:
- **🔍 SELECTOR SEARCH**: Shows what element is being searched for
- **📊 Found Elements**: Lists all interactive elements found on the page
- **🎯 Matching Elements**: Shows which elements match the search criteria
- **🚀 EXECUTING CLICK**: Indicates when an action is being attempted
- **✅ SUCCESS/❌ FAILURE**: Clear indication of action results
### 2. Browser Connection Validation
Use `validate_browser_connection()` to check:
- MCP server connectivity
- Browser responsiveness
- Page accessibility
- Current URL and page title
### 3. Step-by-Step Command Debugging
Use `debug_voice_command()` to analyze:
- How commands are parsed
- Which selectors are generated
- Why actions succeed or fail
- Detailed execution flow
## Using the Debugging Tools
### In LiveKit Agent
When connected to the LiveKit agent, you can use these voice commands:
```
"debug voice command 'click login button'"
"validate browser connection"
"test selectors 'button.login, #login-btn, .signin'"
"capture browser state"
"get debug summary"
```
### Standalone Testing
Run the test scripts to diagnose issues:
```bash
# Test enhanced logging features
python test_enhanced_logging.py
# Test specific login button scenario
python test_login_button_click.py
# Run comprehensive diagnostics
python debug_browser_actions.py
```
## Common Issues and Solutions
### Issue 1: "Selectors found but action not executed"
**Symptoms:**
- Logs show selectors are discovered
- No actual click happens in browser
- No error messages
**Debugging Steps:**
1. Run `validate_browser_connection()` to check connectivity
2. Use `debug_voice_command()` to see execution details
3. Check MCP server logs for errors
4. Verify browser extension is active
**Solution:**
- Ensure MCP server is properly connected to browser
- Check browser console for JavaScript errors
- Restart browser extension if needed
### Issue 2: "No matching elements found"
**Symptoms:**
- Logs show "No elements matched description"
- Interactive elements are found but don't match
**Debugging Steps:**
1. Use `capture_browser_state()` to see page state
2. Use `test_selectors()` with common patterns
3. Check if page has finished loading
**Solution:**
- Try more specific or alternative descriptions
- Wait for page to fully load
- Use CSS selectors directly if needed
### Issue 3: "Browser not responsive"
**Symptoms:**
- Connection validation fails
- No response from browser
**Debugging Steps:**
1. Check if browser is running
2. Verify MCP server is running on correct port
3. Check browser extension status
**Solution:**
- Restart browser and MCP server
- Reinstall browser extension
- Check firewall/network settings
## Enhanced Logging Output
The enhanced logging provides detailed information at each step:
```
🔍 SELECTOR SEARCH: Looking for clickable element matching 'login button'
📋 Step 1: Getting interactive elements from page
📊 Found 15 interactive elements on page
🔍 Element 0: {"tag": "button", "text": "Sign In", "attributes": {"class": "btn-primary"}}
🔍 Element 1: {"tag": "a", "text": "Login", "attributes": {"href": "/login"}}
✅ Found 2 matching elements:
🎯 Match 0: selector='button.btn-primary', reason='text_content=sign in'
🎯 Match 1: selector='a[href="/login"]', reason='text_content=login'
🚀 EXECUTING CLICK: Using selector 'button.btn-primary' (reason: text_content=sign in)
✅ CLICK SUCCESS: Clicked on 'login button' using selector: button.btn-primary
```

# Dynamic Form Filling System
## Overview
The LiveKit agent now features an advanced dynamic form filling system that automatically discovers and fills web forms based on user voice commands. This system is designed to be robust, adaptive, and never relies on hardcoded selectors.
## Key Features
### 🔄 Dynamic Discovery
- **Real-time element discovery** using MCP tools (`chrome_get_interactive_elements`, `chrome_get_content_web_form`)
- **No hardcoded selectors** - all form elements are discovered dynamically
- **Adaptive to different websites** - works across various web platforms
### 🔁 Retry Mechanism
- **Automatic retry** when fields are not found on first attempt
- **Multiple discovery strategies** with increasing flexibility
- **Fallback methods** for challenging form structures
### 🗣️ Natural Language Processing
- **Intelligent field mapping** from natural language to form elements
- **Voice command processing** for hands-free form filling
- **Flexible matching** that understands field variations
## How It Works
### 1. Voice Command Processing
When a user says something like:
- "fill email with john@example.com"
- "enter password secret123"
- "type hello in search box"
The system processes these commands through multiple stages:
```python
# Voice command is parsed to extract field name and value
field_name = "email"
value = "john@example.com"
# Dynamic discovery is triggered
result = await client.fill_field_by_name(field_name, value)
```
### 2. Dynamic Discovery Process
The system follows a multi-step discovery process:
#### Step 1: Cached Fields Check
- First checks if the field is already in the cache
- Uses previously discovered selectors for speed
#### Step 2: Dynamic MCP Discovery
- Uses `chrome_get_interactive_elements` to get fresh form elements
- Analyzes element attributes (name, id, placeholder, aria-label, etc.)
- Matches field descriptions to actual form elements
#### Step 3: Enhanced Detection with Retry
- If initial discovery fails, retries with more flexible matching
- Each retry attempt becomes more permissive in matching criteria
- Up to 3 retry attempts with different strategies
#### Step 4: Content Analysis
- As a final fallback, analyzes page content
- Generates intelligent selectors based on field name patterns
- Tests generated selectors for validity
### 3. Field Matching Algorithm
The system uses sophisticated field matching that considers:
```python
def _is_field_match(element, field_name):
# Check multiple attributes
attributes_to_check = [
"name", "id", "placeholder",
"aria-label", "class", "type"
]
# Field name variations
variations = [
field_name,
field_name.replace(" ", ""),
field_name.replace("_", ""),
# ... more variations
]
# Special type handling
if field_name in ["email", "mail"] and type == "email":
return True
# ... more type-specific logic
```
## Usage Examples
### Basic Voice Commands
```
User: "fill email with john@example.com"
Agent: ✓ Filled 'email' field using dynamic discovery
User: "enter password secret123"
Agent: ✓ Filled 'password' field using cached data
User: "type hello world in search box"
Agent: ✓ Filled 'search' field using enhanced detection
```
### Programmatic Usage
```python
# Direct field filling
result = await client.fill_field_by_name("email", "user@example.com")
# Voice command processing
result = await client.execute_voice_command("fill search with python")
# Pure dynamic discovery (no cache)
result = await client._discover_form_fields_dynamically("username", "john_doe")
```
## API Reference

# Enhanced Field Detection and Filling Workflow
## Overview
This implementation provides an advanced workflow for LiveKit agents to handle missing webpage fields using MCP (Model Context Protocol) for automatic field detection and filling. When a field cannot be found using standard methods, the system automatically employs multiple detection strategies and executes specified actions after successful field population.
## Key Features
### 1. Multi-Strategy Field Detection
The workflow employs five detection strategies in order of preference:
1. **Cached Fields** (Confidence: 0.9)
- Uses pre-detected and cached field information
- Fastest and most reliable method
- Automatically refreshes cache if empty
2. **Enhanced Detection** (Confidence: 0.8)
- Uses intelligent selector generation based on field names
- Supports multiple field name variations and patterns
- Handles common field types (email, password, username, etc.)
3. **Label Analysis** (Confidence: 0.7)
- Analyzes HTML labels and their associations with form fields
- Supports `for` attribute relationships
- Context-aware field matching
4. **Content Analysis** (Confidence: 0.6)
- Analyzes page content for field-related keywords
- Matches form elements based on proximity to keywords
- Handles dynamic content and non-standard field naming
5. **Fallback Patterns** (Confidence: 0.3)
- Last resort using common CSS selectors
- Targets any visible input fields
- Provides basic functionality when all else fails
### 2. Automatic Action Execution
After successful field filling, the workflow can execute a series of actions:
- **submit**: Submit a form (with optional form selector)
- **click**: Click on any element using CSS selector
- **navigate**: Navigate to a new URL
- **wait**: Pause execution for specified time
- **keyboard**: Send keyboard input (Enter, Tab, etc.)
### 3. Comprehensive Error Handling
- Detailed error reporting for each detection strategy
- Graceful fallback between strategies
- Action-level error handling with optional/required flags
- Execution time tracking and performance metrics
## Implementation Details
### Core Method: `execute_field_workflow`
```python
async def execute_field_workflow(
self,
field_name: str,
field_value: str,
actions: list = None,
max_retries: int = 3
) -> dict:
```
**Parameters:**
- `field_name`: Name or identifier of the field to find
- `field_value`: Value to fill in the field

# Real-Time Form Discovery System
## Overview
The LiveKit agent now features a **REAL-TIME ONLY** form discovery system that **NEVER uses cached selectors**. Every form field discovery is performed live using MCP tools, ensuring the most current and accurate form element detection.
## Key Principles
### 🚫 NO CACHE POLICY
- **Zero cached selectors** - every request gets fresh selectors
- **Real-time discovery only** - uses MCP tools on every call
- **No hardcoded selectors** - all elements discovered dynamically
- **Fresh page analysis** - adapts to dynamic content changes
### 🔄 Real-Time MCP Tools
- **chrome_get_interactive_elements** - Gets current form elements
- **chrome_get_content_web_form** - Analyzes form structure
- **chrome_get_web_content** - Content analysis for field discovery
- **Live selector testing** - Validates selectors before use
## How Real-Time Discovery Works
### 1. Voice Command Processing
When a user says: `"fill email with john@example.com"`
```python
# NO cache lookup - goes straight to real-time discovery
field_name = "email"
value = "john@example.com"
# Step 1: Real-time MCP discovery
discovery_result = await client._discover_form_fields_dynamically(field_name, value)
# Step 2: Enhanced detection with retry (if needed)
enhanced_result = await client._enhanced_field_detection_with_retry(field_name, value)
# Step 3: Direct MCP element search (final fallback)
direct_result = await client._direct_mcp_element_search(field_name, value)
```
### 2. Real-Time Discovery Process
#### Strategy 1: Interactive Elements Discovery
```python
# Get ALL current interactive elements
interactive_result = await client._call_mcp_tool("chrome_get_interactive_elements", {
"types": ["input", "textarea", "select"]
})
# Match field name to current elements
for element in elements:
if client._is_field_match(element, field_name):
selector = client._extract_best_selector(element)
# Try to fill immediately with fresh selector
```
#### Strategy 2: Form Content Analysis
```python
# Get current form structure
form_result = await client._call_mcp_tool("chrome_get_content_web_form", {})
# Parse form content for field patterns
selector = client._parse_form_content_for_field(form_content, field_name)
# Test and use selector immediately
```
#### Strategy 3: Direct Element Search
```python
# Exhaustive search through ALL elements
all_elements = await client._call_mcp_tool("chrome_get_interactive_elements", {})
# Very flexible matching for any possible match
for element in all_elements:
if client._is_very_flexible_match(element, field_name):
# Generate and test selector immediately
```
### 3. Real-Time Selector Generation
The system generates selectors in real-time based on current element attributes:
```python
def _extract_best_selector(element):
attrs = element.get("attributes", {})
# Priority order for reliability
if attrs.get("id"):
return f"#{attrs['id']}"
if attrs.get("name"):
return f"input[name='{attrs['name']}']"
if attrs.get("type") and attrs.get("name"):
return f"input[type='{attrs['type']}'][name='{attrs['name']}']"
# ... more patterns
```
## API Reference
### Real-Time Functions
#### `fill_field_by_name(field_name: str, value: str) -> str`
**NOW REAL-TIME ONLY** - No cache, fresh discovery every call.
#### `fill_field_realtime_only(field_name: str, value: str) -> str`
**Guaranteed real-time** - Explicit real-time discovery function.
#### `get_realtime_form_fields() -> str`
**Live form discovery** - Gets current form fields using only MCP tools.
#### `_discover_form_fields_dynamically(field_name: str, value: str) -> dict`
**Pure real-time discovery** - Uses chrome_get_interactive_elements and chrome_get_content_web_form.
#### `_direct_mcp_element_search(field_name: str, value: str) -> dict`
**Exhaustive real-time search** - Final fallback using comprehensive MCP element search.
### Real-Time Matching Algorithms
#### `_is_field_match(element: dict, field_name: str) -> bool`
Standard real-time field matching using current element attributes.
#### `_is_very_flexible_match(element: dict, field_name: str) -> bool`
Very flexible real-time matching for challenging cases.
#### `_generate_common_selectors(field_name: str) -> list`
Generates common CSS selectors based on field name patterns.
## Usage Examples
### Voice Commands (All Real-Time)
```
User: "fill email with john@example.com"
Agent: [Uses chrome_get_interactive_elements] ✓ Filled 'email' field using real-time discovery
User: "enter password secret123"
Agent: [Uses chrome_get_content_web_form] ✓ Filled 'password' field using form content analysis
User: "type hello in search box"
Agent: [Uses direct MCP search] ✓ Filled 'search' field using exhaustive element search
```
### Programmatic Usage
```python
# All these functions use ONLY real-time discovery
result = await client.fill_field_by_name("email", "user@example.com")
result = await client.fill_field_realtime_only("search", "python")
result = await client._discover_form_fields_dynamically("username", "john_doe")

# QuBeCare Login Form Troubleshooting Guide
## Issue: LiveKit Agent Not Filling QuBeCare Login Form
### Potential Causes and Solutions
#### 1. **Page Loading Issues**
- **Problem**: Form elements not loaded when agent tries to fill them
- **Solution**:
- Ensure page is fully loaded before attempting form filling
- Add delays after navigation: `await asyncio.sleep(3)`
- Check page load status with JavaScript
#### 2. **Dynamic Form Elements**
- **Problem**: QuBeCare uses React/Vue.js with dynamically generated form elements
- **Solution**:
- Use enhanced form detection with JavaScript execution
- Wait for elements to appear in DOM
- Use MutationObserver to detect when forms are ready
#### 3. **Shadow DOM or iFrames**
- **Problem**: Login form is inside shadow DOM or iframe
- **Solution**:
- Check for iframe elements: `document.querySelectorAll('iframe')`
- Switch to iframe context before form filling
- Handle shadow DOM with special selectors
#### 4. **CSRF Protection or Security Measures**
- **Problem**: Site blocks automated form filling
- **Solution**:
- Simulate human-like interactions
- Add random delays between actions
- Use proper user agent and headers
#### 5. **Incorrect Selectors**
- **Problem**: Form field selectors have changed or are non-standard
- **Solution**:
- Use the enhanced form detection method
- Try multiple selector strategies
- Inspect actual DOM structure
### Debugging Steps
#### Step 1: Run the Debug Script
```bash
cd agent-livekit
python debug_form_detection.py
```
#### Step 2: Check Agent Logs
Look for these log messages:
- "Auto-detecting all input fields on current page..."
- "Enhanced detection found X elements"
- "Filling field 'selector' with value 'value'"
#### Step 3: Manual Testing
1. Navigate to https://app.qubecare.ai/provider/login
2. Use agent command: `get_form_fields`
3. If no fields found, try: `refresh_input_fields`
4. Use the new specialized command: `fill_qubecare_login email@example.com password123`
#### Step 4: Browser Developer Tools
1. Open browser dev tools (F12)
2. Go to Console tab
3. Run: `document.querySelectorAll('input, textarea, select')`
4. Check if elements are visible and accessible
### Enhanced Commands Available
#### New QuBeCare-Specific Command
```
fill_qubecare_login email@example.com your_password
```
#### Enhanced Form Detection
```
get_form_fields # Now includes JavaScript-based detection
refresh_input_fields # Manually refresh field cache
```
#### Debug Commands
```
navigate_to_url https://app.qubecare.ai/provider/login
get_form_fields
fill_qubecare_login your_email@domain.com your_password
submit_form
```
### Common Issues and Fixes
#### Issue: "No form fields found"
**Fix**:
1. Wait longer for page load
2. Check if page requires login or has redirects
3. Verify URL is correct and accessible
#### Issue: "Error filling form field"
**Fix**:
1. Check if field is visible and enabled
2. Try clicking field first to focus it
3. Use different selector strategy
#### Issue: Form fills but doesn't submit
**Fix**:
1. Use `submit_form` command after filling
2. Try pressing Enter key on form
3. Look for submit button and click it
### Technical Implementation Details
The enhanced form detection now:
1. Uses multiple detection strategies
2. Executes JavaScript to find hidden/dynamic elements
3. Provides detailed field information including visibility
4. Identifies login-specific fields automatically
5. Handles modern web application patterns
### Next Steps if Issues Persist
1. **Check Network Connectivity**: Ensure agent can reach QuBeCare servers
2. **Verify Credentials**: Test login manually in browser
3. **Update Selectors**: QuBeCare may have updated their form structure
4. **Check for Captcha**: Some login forms require human verification
5. **Review Browser Profile**: Ensure correct browser profile is being used
### Contact Support
If the issue persists after trying these solutions:
1. Provide debug script output
2. Share agent logs
3. Include browser developer tools console output
4. Specify exact error messages received

# Persistent Connection Implementation Summary
## Overview
Modified the Chrome extension to implement persistent connection management that maintains connections until explicitly disconnected by the user.
## Key Changes Made
### 1. Enhanced RemoteServerClient (`utils/remote-server-client.ts`)
#### Connection State Persistence
- **Added persistent connection state management**:
- `persistentConnectionEnabled = true` by default
- `connectionStateKey = 'remoteServerConnectionState'` for storage
- Automatic state saving/loading to chrome.storage.local
#### New Methods Added
- `saveConnectionState()`: Saves connection state to chrome storage
- `loadConnectionState()`: Loads and restores connection state on startup
- `clearConnectionState()`: Clears saved state on manual disconnect
- `setPersistentConnection(enabled)`: Enable/disable persistent behavior
- `isPersistentConnectionEnabled()`: Get current persistence setting
#### Enhanced Reconnection Logic
- **Increased max reconnection attempts**: From 10 to 50 for persistent connections
- **Extended reconnection delays**: Up to 60 seconds for persistent connections
- **Smarter reconnection**: Only attempts reconnection for unexpected disconnections
- **Connection restoration**: Automatically restores connections within 24 hours
#### Connection Lifecycle Improvements
- **State saving on connect**: Automatically saves state when connection established
- **State clearing on disconnect**: Clears state only on manual disconnect
- **Robust error handling**: Better handling of connection timeouts and errors
### 2. Enhanced Background Script (`entrypoints/background/index.ts`)
#### Browser Event Listeners
- **Added `initBrowserEventListeners()`** function with listeners for:
- `chrome.runtime.onStartup`: Browser startup detection
- `chrome.runtime.onInstalled`: Extension install/update events
- `chrome.runtime.onSuspend`: Browser suspension events
- `chrome.tabs.onActivated`: Tab switch monitoring
- `chrome.windows.onFocusChanged`: Window focus monitoring
#### Connection Health Monitoring
- **Added `startConnectionHealthCheck()`**: 5-minute interval health checks
- **Periodic status logging**: Regular connection status verification
- **Proactive monitoring**: Detects and logs connection state changes
### 3. Enhanced Popup UI (`entrypoints/popup/App.vue`)
#### Visual Indicators
- **Persistent connection badge**: "🔗 Persistent: Active" indicator
- **Enhanced status text**: "Connected (Persistent)" vs "Disconnected - Click Connect for persistent connection"
- **Persistent info message**: "🔗 Connection will persist until manually disconnected"
#### CSS Styling
- **`.persistent-indicator`**: Styling for persistent connection elements
- **`.persistent-badge`**: Green gradient badge with shadow
- **`.persistent-info`**: Info box with green accent border
#### Status Text Updates
- **Clear messaging**: Emphasizes persistent nature of connections
- **User guidance**: Explains that connections persist until manual disconnect
## Technical Implementation Details
### Connection State Storage
```javascript
const state = {
wasConnected: boolean,
connectionTime: number,
serverUrl: string,
lastSaveTime: number
}
```
### Reconnection Strategy
- **Exponential backoff**: 5s, 10s, 20s, 40s, up to 60s intervals
- **Persistent attempts**: Up to 50 attempts for persistent connections
- **Smart restoration**: Only restores connections from last 24 hours
### Browser Event Handling
- **Tab switches**: Connection maintained across all tab operations
- **Window focus**: Connection persists during window focus changes
- **Browser suspension**: State saved before suspension, restored after
- **Extension updates**: Connection state preserved across updates
## Behavior Changes
### Before Implementation
- Manual connection required each session
- Connections might not survive browser events
- Limited reconnection attempts (10)
- No connection state persistence
### After Implementation
- **"Connect once, stay connected"** behavior
- **Connections persist across**:
- Popup open/close cycles
- Browser tab switches
- Window focus changes
- Extended idle periods
- Browser suspension/resume
- **Robust reconnection**: Up to 50 attempts with smart backoff
- **State restoration**: Automatic connection restoration after browser restart
- **Manual disconnect only**: Connections only terminate when explicitly disconnected
## User Experience Improvements
### Clear Visual Feedback
- Persistent connection status clearly indicated
- Real-time connection duration display
- Visual badges and indicators for connection state
### Predictable Behavior
- Users know connections will persist until manually disconnected
- No unexpected disconnections during tool operations
- Consistent behavior across browser lifecycle events
### Robust Connectivity
- Automatic reconnection when server becomes available
- Connection state restoration after browser restart
- Extended retry attempts for better reliability
## Testing
- Comprehensive test plan provided in `PERSISTENT_CONNECTION_TEST_PLAN.md`
- Covers all aspects of persistent connection behavior
- Includes verification points and success criteria
## Compatibility
- Maintains backward compatibility with existing MCP clients
- No breaking changes to tool execution or API

# Persistent Connection Test Plan
## Overview
This test plan verifies that the Chrome extension implements persistent connection management as requested:
- Connections remain active after manual connect until explicit disconnect
- Connections persist across popup open/close cycles
- Connections survive browser events (tab switches, window focus changes, idle periods)
- No automatic disconnection after tool operations
## Prerequisites
1. **Remote Server Running**: Start the remote server on `ws://localhost:3001/chrome`
```bash
cd app/remote-server
npm run dev
```
2. **Extension Loaded**: Load the built extension from `app/chrome-extension/.output/chrome-mv3`
## Test Cases
### Test 1: Basic Persistent Connection
**Objective**: Verify connection persists after popup close
**Steps**:
1. Open Chrome extension popup
2. Click "Connect" button
3. Verify connection status shows "Connected (Persistent)" with green checkmark
4. Note the persistent connection indicator: "🔗 Persistent: Active"
5. Close the popup window
6. Wait 30 seconds
7. Reopen the popup
**Expected Result**:
- Connection status still shows "Connected (Persistent)"
- Connection time continues counting from original connection
- No reconnection attempts logged
### Test 2: Connection Persistence Across Browser Events
**Objective**: Verify connection survives browser lifecycle events
**Steps**:
1. Establish connection (Test 1)
2. Switch between multiple tabs
3. Change window focus to different applications
4. Minimize/restore browser window
5. Open new browser windows
6. Check popup status after each event
**Expected Result**:
- Connection remains active throughout all events
- No disconnection or reconnection attempts
- Status consistently shows "Connected (Persistent)"
### Test 3: Tool Execution Without Disconnection
**Objective**: Verify connection persists during and after tool operations
**Steps**:
1. Establish connection
2. Use Cherry Studio or another MCP client to send tool requests:
- `chrome_navigate` to navigate to a website
- `chrome_screenshot` to take screenshots
- `chrome_extract_content` to extract page content
3. Execute multiple tool operations in sequence
4. Check connection status after each operation
**Expected Result**:
- All tool operations complete successfully
- Connection remains active after each operation
- No automatic disconnection after tool completion
### Test 4: Extended Idle Period Test
**Objective**: Verify connection survives long idle periods
**Steps**:
1. Establish connection
2. Leave browser idle for 30 minutes
3. Do not interact with the extension or browser
4. After 30 minutes, check popup status
5. Test tool functionality by sending a simple request
**Expected Result**:
- Connection remains active after idle period
- Tool operations work immediately without reconnection
- Connection time shows full duration including idle time
### Test 5: Manual Disconnect Only
**Objective**: Verify connection only terminates on explicit disconnect
**Steps**:
1. Establish connection
2. Perform various activities (tabs, tools, idle time)
3. Click "Disconnect" button in popup
4. Verify disconnection
5. Close and reopen popup
**Expected Result**:
- Connection terminates only when "Disconnect" is clicked
- After disconnect, status shows "Disconnected - Click Connect for persistent connection"
- Popup reopening shows disconnected state
- No automatic reconnection attempts
### Test 6: Browser Restart Connection Restoration
**Objective**: Verify connection state restoration after browser restart
**Steps**:
1. Establish connection
2. Close entire browser (all windows)
3. Restart browser
4. Open extension popup immediately
**Expected Result**:
- Extension attempts to restore previous connection
- If server is still running, connection is re-established automatically
- If successful, shows "Connected (Persistent)" status
### Test 7: Server Reconnection Behavior
**Objective**: Verify robust reconnection when server becomes unavailable
**Steps**:
1. Establish connection
2. Stop the remote server
3. Wait for connection loss detection
4. Restart the remote server
5. Monitor reconnection attempts
**Expected Result**:
- Extension detects connection loss
- Automatic reconnection attempts begin
- Connection is restored when server comes back online
- Persistent connection behavior resumes
## Verification Points
### UI Indicators
- ✅ Status shows "Connected (Persistent)" when connected
- ✅ Persistent badge shows "🔗 Persistent: Active"
- ✅ Info text: "🔗 Connection will persist until manually disconnected"
- ✅ Connection time continues counting accurately
- ✅ Disconnect button changes to "Disconnect" when connected
### Console Logs
Monitor browser console for these log messages:
- `Background: Remote server client initialized (not connected)`
- `Background: Browser event listeners initialized for connection persistence`
- `Background: Connection health check started (5-minute intervals)`
- `RemoteServerClient: Connection state saved`
- `Background: Tab switched to X, connection maintained`
- `Background: Window focus changed to X, connection maintained`
### Connection State Persistence
- Connection state is saved to chrome.storage.local
- State includes: wasConnected, connectionTime, serverUrl, lastSaveTime
- State is restored on extension startup if recent (within 24 hours)
## Success Criteria
All test cases pass with:
1. ✅ Connections persist until manual disconnect
2. ✅ No automatic disconnection after tool operations
3. ✅ Connections survive all browser lifecycle events
4. ✅ UI clearly indicates persistent connection status
5. ✅ Robust reconnection when server connectivity is restored
6. ✅ Connection state restoration after browser restart
## Troubleshooting
If tests fail, check:
1. Remote server is running on correct port (3001)
2. Extension has proper permissions
3. Browser console for error messages
4. Chrome storage for saved connection state
5. Network connectivity between extension and server

# Chrome Extension User ID Guide
## Overview
The Chrome extension automatically generates and manages unique user IDs when connecting to the remote server. This guide explains how to access and use these user IDs.
## How User IDs Work
### 1. **Automatic Generation**
- Each Chrome extension instance generates a unique user ID in the format: `user_{timestamp}_{random}`
- Example: `user_1704067200000_abc123def456`
- User IDs are persistent across browser sessions (stored in chrome.storage.local)
### 2. **User ID Display in Popup**
When connected to the remote server, the popup will show:
- **User ID section** with the current user ID
- **Truncated display** for long IDs (shows first 8 and last 8 characters)
- **Copy button** (📋) to copy the full user ID to clipboard
- **Tooltip** showing the full user ID on hover
## Getting User ID Programmatically
### 1. **From Popup/Content Scripts**
```javascript
// Send message to background script to get user ID
const response = await chrome.runtime.sendMessage({ type: 'getCurrentUserId' });
if (response && response.success) {
const userId = response.userId;
console.log('Current User ID:', userId);
} else {
console.log('No user ID available or not connected');
}
```
### 2. **From Background Script**
```javascript
import { getRemoteServerClient } from './background/index';
// Get the remote server client instance
const client = getRemoteServerClient();
if (client) {
const userId = await client.getCurrentUserId();
console.log('Current User ID:', userId);
}
```
### 3. **Direct Storage Access**
```javascript
// Get user ID directly from chrome storage
const result = await chrome.storage.local.get(['chrome_extension_user_id']);
const userId = result.chrome_extension_user_id;
console.log('Stored User ID:', userId);
```
## User ID Lifecycle
### 1. **Generation**
- User ID is generated on first connection to remote server
- Stored in `chrome.storage.local` with key `chrome_extension_user_id`
- Persists across browser restarts and extension reloads
### 2. **Usage**
- Sent to remote server during connection handshake
- Used for session management and routing
- Enables multi-user support with session isolation
### 3. **Display**
- Shown in popup when connected to remote server
- Updates automatically when connection status changes
- Cleared from display when disconnected
## Remote Server Integration
### 1. **Connection Info**
When connecting, the extension sends:
```javascript
{
type: 'connection_info',
userId: 'user_1704067200000_abc123def456',
userAgent: navigator.userAgent,
timestamp: Date.now(),
extensionId: chrome.runtime.id
}
```
### 2. **Server-Side Access**
The remote server receives and uses the user ID for:
- Session management
- LiveKit room assignment (`mcp-chrome-user-{userId}`)
- Command routing
- User isolation
## Troubleshooting
### 1. **User ID Not Showing**
- Ensure you're connected to the remote server
- Check browser console for connection errors
- Verify remote server is running and accessible
### 2. **User ID Changes**
- User IDs should persist across sessions
- If changing frequently, check chrome.storage permissions
- Clear extension data to force new user ID generation
### 3. **Copy Function Not Working**
- Ensure clipboard permissions are granted
- Check for HTTPS context requirements
- Fallback: manually select and copy from tooltip
## API Reference
### Background Script Messages
#### `getCurrentUserId`
```javascript
// Request
{ type: 'getCurrentUserId' }
// Response
{
success: true,
userId: 'user_1704067200000_abc123def456'
}
// or
{
success: false,
error: 'Remote server client not initialized'
}
```
### Storage Keys
#### `chrome_extension_user_id`
- **Type**: String
- **Format**: `user_{timestamp}_{random}`
- **Persistence**: Permanent (until extension data cleared)
- **Access**: chrome.storage.local
## Best Practices
1. **Always check connection status** before requesting user ID
2. **Handle null/undefined user IDs** gracefully
3. **Use the background script API** for reliable access
4. **Don't hardcode user IDs** - they should be dynamic
5. **Respect user privacy** - user IDs are anonymous but unique
## Example Implementation
```javascript
// Complete example of getting and using user ID
async function handleUserIdExample() {
try {
// Get current user ID
const response = await chrome.runtime.sendMessage({
type: 'getCurrentUserId'
});
if (response && response.success && response.userId) {
console.log('✅ User ID:', response.userId);
// Use the user ID for your application logic
await processUserSpecificData(response.userId);
} else {
console.log('❌ No user ID available');
console.log('Make sure you are connected to the remote server');
}
} catch (error) {
console.error('Failed to get user ID:', error);
}
}
async function processUserSpecificData(userId) {
// Your application logic here
console.log(`Processing data for user: ${userId}`);
}
```

# MCP Chrome Remote Server
A remote server implementation for the MCP Chrome Bridge that allows external applications to control Chrome through **direct WebSocket connections**.
## 🚀 New Direct Connection Architecture
This server now supports **direct connections** from Chrome extensions, eliminating the need for native messaging hosts as intermediaries:
- **Cherry Studio** → **Remote Server** (via Streamable HTTP)
- **Chrome Extension** → **Remote Server** (via WebSocket)
- **No Native Server Required** for Chrome extension communication
### Benefits
- ✅ Eliminates 10-second timeout errors
- ✅ Faster response times
- ✅ Simplified architecture
- ✅ Better reliability
- ✅ Easier debugging
## Features
- **Remote Control**: Control Chrome browser remotely via WebSocket API
- **MCP Protocol**: Implements Model Context Protocol for tool-based interactions
- **HTTP Streaming**: Full support for MCP Streamable HTTP and SSE (Server-Sent Events)
- **Real-time Communication**: WebSocket-based real-time communication with Chrome extensions
- **RESTful Health Checks**: HTTP endpoints for monitoring server health
- **Extensible Architecture**: Easy to add new Chrome automation tools
- **Session Management**: Robust session handling for streaming connections
## Quick Start
### 1. Install Dependencies (from project root)
```bash
# Install all workspace dependencies
pnpm install
```
### 2. Build the Server
```bash
# From project root
npm run build:remote
# Or from this directory
npm run build
```
### 3. Start the Server
```bash
# From project root (recommended)
npm run start:server
# Or from this directory
npm run start:server
```
The server will start on `http://localhost:3001` by default.
### 4. Verify Server is Running
You should see output like:
```
🚀 MCP Remote Server started successfully!
📡 Server running at: http://0.0.0.0:3001
🔌 WebSocket endpoint: ws://0.0.0.0:3001/ws/mcp
🔌 Chrome extension endpoint: ws://0.0.0.0:3001/chrome
🌊 Streaming HTTP endpoint: http://0.0.0.0:3001/mcp
📡 SSE endpoint: http://0.0.0.0:3001/sse
```
### 5. Test the Connection
```bash
# Test WebSocket connection
node test-client.js
# Test streaming HTTP connection
node test-tools-list.js
# Test SSE connection
node test-sse-client.js
# Test simple health check
node test-health.js
```
## Available Scripts
- `npm run start:server` - Build and start the production server
- `npm run start` - Start the server (requires pre-built dist/)
- `npm run dev` - Start development server with auto-reload
- `npm run build` - Build TypeScript to JavaScript
- `npm run test` - Run tests
- `npm run lint` - Run ESLint
- `npm run format` - Format code with Prettier
## Environment Variables
- `PORT` - Server port (default: 3001)
- `HOST` - Server host (default: 0.0.0.0)
## API Endpoints
### HTTP Endpoints
- `GET /health` - Health check endpoint
### Streaming HTTP Endpoints (MCP Protocol)
- `POST /mcp` - Send MCP messages (initialization, tool calls, etc.)
- `GET /mcp` - Establish SSE stream for receiving responses (requires MCP-Session-ID header)
- `DELETE /mcp` - Terminate MCP session (requires MCP-Session-ID header)
### SSE Endpoints
- `GET /sse` - Server-Sent Events endpoint for MCP communication
- `POST /messages` - Send messages to SSE session (requires X-Session-ID header)
### WebSocket Endpoints
- `WS /ws/mcp` - MCP protocol WebSocket endpoint for Chrome control
- `WS /chrome` - Chrome extension WebSocket endpoint
## Available Tools
The server provides the following Chrome automation tools:
1. **navigate_to_url** - Navigate to a specific URL
2. **get_page_content** - Get page text content
3. **click_element** - Click on elements using CSS selectors
4. **fill_input** - Fill input fields with text
5. **take_screenshot** - Capture page screenshots
## Usage Examples
### Streamable HTTP Connection (Recommended)
```javascript
import fetch from 'node-fetch';
const SERVER_URL = 'http://localhost:3001';
const MCP_URL = `${SERVER_URL}/mcp`;
// Step 1: Initialize session
const initResponse = await fetch(MCP_URL, {
method: 'POST',
headers: {
'Content-Type': 'application/json',
Accept: 'application/json, text/event-stream',
},
body: JSON.stringify({
jsonrpc: '2.0',
id: 1,
method: 'initialize',
params: {
protocolVersion: '2024-11-05',
capabilities: { tools: {} },
clientInfo: { name: 'my-client', version: '1.0.0' },
},
}),
});
const sessionId = initResponse.headers.get('mcp-session-id');
// Step 2: Call tools
const toolResponse = await fetch(MCP_URL, {
method: 'POST',
headers: {
'Content-Type': 'application/json',
Accept: 'application/json, text/event-stream',
'MCP-Session-ID': sessionId,
},
body: JSON.stringify({
jsonrpc: '2.0',
id: 2,
method: 'tools/call',
params: {
name: 'navigate_to_url',
arguments: { url: 'https://example.com' },
},
}),
});
const result = await toolResponse.text(); // SSE format
```
### WebSocket Connection
```javascript
const ws = new WebSocket('ws://localhost:3001/ws/mcp');
// Navigate to a URL
ws.send(
JSON.stringify({
method: 'tools/call',
params: {
name: 'navigate_to_url',
arguments: { url: 'https://example.com' },
},
}),
);
// Get page content
ws.send(
JSON.stringify({
method: 'tools/call',
params: {
name: 'get_page_content',
arguments: {},
},
}),
);
```
## Streaming Capabilities
The MCP Remote Server now supports multiple connection types:
### 1. **Streamable HTTP (Recommended)**
- Full MCP protocol compliance
- Session-based communication
- Server-Sent Events for real-time responses
- Stateful connections with session management
- Compatible with MCP clients like CherryStudio
### 2. **Server-Sent Events (SSE)**
- Real-time streaming communication
- Lightweight alternative to WebSockets
- HTTP-based with automatic reconnection
### 3. **WebSocket (Legacy)**
- Real-time bidirectional communication
- Backward compatibility with existing clients
## Architecture
```
┌─────────────────┐ HTTP/SSE ┌──────────────────┐ WebSocket ┌─────────────────┐
│ MCP Client │ ◄──────────────► │ Remote Server │ ◄─────────────────► │ Chrome Extension │
│ (External App) │ WebSocket │ (This Server) │ │ │
└─────────────────┘ └──────────────────┘ └─────────────────┘
```
## Development
### Project Structure
```
src/
├── index.ts # Main server entry point
├── server/
│ ├── mcp-remote-server.ts # MCP protocol implementation
│ └── chrome-tools.ts # Chrome automation tools
└── types/ # TypeScript type definitions
```
### Adding New Tools
1. Add the tool definition in `mcp-remote-server.ts`
2. Implement the tool logic in `chrome-tools.ts`
3. Update the Chrome extension to handle new actions
## Troubleshooting
### Common Issues
1. **Server won't start**: Check if port 3000 is available
2. **Chrome extension not connecting**: Ensure the extension is installed and enabled
3. **WebSocket connection fails**: Check firewall settings and CORS configuration
### Logs
The server uses structured logging with Pino. Check console output for detailed error messages and debugging information.

# Multi-User Chrome Extension to LiveKit Agent Integration
This document explains how the system automatically spawns LiveKit agents for each Chrome extension user connection, creating a seamless multi-user voice automation experience.
## Overview
The system now automatically creates a dedicated LiveKit agent for each user who installs and connects the Chrome extension. Each user gets:
- **Unique Random User ID** - Generated by Chrome extension and consistent across all components
- **Dedicated LiveKit Agent** - Automatically started for each user with the same user ID
- **Isolated Voice Room** - Each user gets their own LiveKit room (`mcp-chrome-user-{userId}`)
- **Session-Based Routing** - Voice commands routed to correct user's Chrome extension
- **Complete User ID Consistency** - Same user ID flows through Chrome → Server → Agent → Back to Chrome
## Architecture Flow
```
Chrome Extension (User 1) → Random User ID → LiveKit Agent (Room: mcp-chrome-user-{userId})
Chrome Extension (User 2) → Random User ID → LiveKit Agent (Room: mcp-chrome-user-{userId})
Chrome Extension (User 3) → Random User ID → LiveKit Agent (Room: mcp-chrome-user-{userId})
↓
Remote Server (Session Manager)
↓
Connection Router & LiveKit Agent Manager
```
## How It Works
### 1. Chrome Extension Connection
When a user installs and connects the Chrome extension:
```javascript
// Chrome extension generates unique user ID
const userId = `user_${Date.now()}_${Math.random().toString(36).substring(2, 15)}`;
// Chrome extension connects to ws://localhost:3001/chrome with user ID
const connectionInfo = {
type: 'connection_info',
userId: userId, // Chrome extension provides its own user ID
userAgent: navigator.userAgent,
timestamp: Date.now(),
extensionId: chrome.runtime.id,
};
// Remote server receives and uses the Chrome extension's user ID
// Session created with user-provided ID: session_user_1703123456_abc123
```
### 2. Manual LiveKit Agent Management
LiveKit agents are no longer started automatically. They should be started manually when needed:
```typescript
// LiveKit Agent Manager can spawn agent process with user ID when requested
const roomName = `mcp-chrome-user-${userId}`;
const agentProcess = spawn('python', ['livekit_agent.py', 'start'], {
env: {
...process.env,
CHROME_USER_ID: userId, // Pass user ID to LiveKit agent
LIVEKIT_URL: this.liveKitConfig.livekit_url,
LIVEKIT_API_KEY: this.liveKitConfig.api_key,
LIVEKIT_API_SECRET: this.liveKitConfig.api_secret,
MCP_SERVER_URL: 'http://localhost:3001/mcp',
},
});
```
### 3. User-Specific Voice Room
Each user gets their own LiveKit room:
```
User 1 → Room: mcp-chrome-user-user_1703123456_abc123
User 2 → Room: mcp-chrome-user-user_1703123457_def456
User 3 → Room: mcp-chrome-user-user_1703123458_ghi789
```
### 4. Session-Based Command Routing with User ID
Voice commands are routed to the correct Chrome extension using user ID:
```python
# LiveKit agent includes user ID in MCP requests
async def search_google(context: RunContext, query: str):
# MCP client automatically includes user ID in headers
result = await self.mcp_client._search_google_mcp(query)
return result
```
```typescript
// Remote server routes commands based on user ID
const result = await this.sendToExtensions(message, sessionId, userId);
// Connection router finds the correct Chrome extension by user ID
```
```
LiveKit Agent (User 1) → [User ID: user_123_abc] → Remote Server → Chrome Extension (User 1)
LiveKit Agent (User 2) → [User ID: user_456_def] → Remote Server → Chrome Extension (User 2)
LiveKit Agent (User 3) → [User ID: user_789_ghi] → Remote Server → Chrome Extension (User 3)
```

## Console Logging
### When Chrome Extension Connects:
```
🔗 Chrome extension connected - User: user_1703123456_abc123, Session: session_user_1703123456_abc123
🚀 Starting LiveKit agent for user: user_1703123456_abc123
✅ LiveKit agent started successfully for user user_1703123456_abc123
```
### When LiveKit Agent Starts:
```
============================================================
🔗 NEW USER SESSION CONNECTED
============================================================
👤 User ID: user_1703123456_abc123
🆔 Session ID: session_user_1703123456_abc123
🏠 Room Name: mcp-chrome-user-user_1703123456_abc123
🎭 Participant: chrome_user_user_1703123456_abc123
⏰ Connected At: 1703123456.789
📊 Total Active Sessions: 1
============================================================
🔗 Detected Chrome user ID from room name: user_1703123456_abc123
✅ LiveKit agent connected to Chrome user: user_1703123456_abc123
```
### When User Issues Voice Commands:
```
🌐 [Session: session_user_1703123456_abc123] Navigation to: https://google.com
✅ [Session: session_user_1703123456_abc123] Navigation completed
🔍 [Session: session_user_1703123456_abc123] Google search: 'python programming'
✅ [Session: session_user_1703123456_abc123] Search completed
```
### When Chrome Extension Disconnects:
```
🔌 Chrome extension disconnected
🛑 Stopping LiveKit agent for user: user_1703123456_abc123
✅ LiveKit agent stopped for user user_1703123456_abc123
```
## Setup Instructions
### 1. Start Remote Server
```bash
cd app/remote-server
npm start
```
### 2. Install Chrome Extensions (Multiple Users)
Each user:
1. Open Chrome → Extensions → Developer mode ON
2. Click "Load unpacked"
3. Select: `app/chrome-extension/.output/chrome-mv3/`
4. Extension automatically connects and gets unique user ID
### 3. Configure Cherry Studio (Each User)
Each user adds to their Cherry Studio:
```json
{
"mcpServers": {
"chrome-mcp-remote-server": {
"type": "streamableHttp",
"url": "http://localhost:3001/mcp"
}
}
}
```
### 4. Join LiveKit Rooms (Each User)
Each user joins their specific room:
- User 1: `mcp-chrome-user-user_1703123456_abc123`
- User 2: `mcp-chrome-user-user_1703123457_def456`
- User 3: `mcp-chrome-user-user_1703123458_ghi789`
## Testing
### Test Multi-User Integration:
```bash
cd app/remote-server
node test-multi-user-livekit.js
```
This test:
1. Simulates multiple Chrome extension connections
2. Verifies unique user ID generation
3. Checks LiveKit agent spawning
4. Tests session isolation
5. Validates room naming
### Expected Test Output:
```
👤 User 1: Chrome extension connected
📋 User 1: Received session info: { userId: "user_...", sessionId: "session_..." }
🚀 User 1: LiveKit agent should be starting for room: mcp-chrome-user-user_...
👤 User 2: Chrome extension connected
📋 User 2: Received session info: { userId: "user_...", sessionId: "session_..." }
🚀 User 2: LiveKit agent should be starting for room: mcp-chrome-user-user_...
✅ Session isolation: PASS
✅ User ID isolation: PASS
✅ Room isolation: PASS
```
## Benefits
### 1. **Zero Configuration**
- Users just install Chrome extension
- LiveKit agents start automatically
- No manual room setup required
### 2. **Complete Isolation**
- Each user has dedicated agent
- Separate voice rooms
- Independent command processing
### 3. **Scalable Architecture**
- Supports unlimited concurrent users
- Automatic resource management
- Process cleanup on disconnect
### 4. **Session Persistence**
- User sessions tracked across connections
- Automatic reconnection handling
- State management per user
## Monitoring
### Agent Statistics:
```javascript
// Get LiveKit agent stats
const stats = chromeTools.getLiveKitAgentStats();
console.log(stats);
// Output: { totalAgents: 3, runningAgents: 3, startingAgents: 0, ... }
```
### Active Agents:
```javascript
// Get all active agents
const agents = chromeTools.getAllActiveLiveKitAgents();
agents.forEach((agent) => {
console.log(`User: ${agent.userId}, Room: ${agent.roomName}, Status: ${agent.status}`);
});
```
## Troubleshooting
### Common Issues:
1. **LiveKit Agent Not Starting**
- Check Python environment in `agent-livekit/`
- Verify LiveKit server is running
- Check agent process logs
2. **Multiple Agents for Same User**
- Check user ID generation uniqueness
- Verify session cleanup on disconnect
3. **Voice Commands Not Working**
- Verify user is in correct LiveKit room
- Check session routing in logs
- Confirm Chrome extension connection
### Debug Commands:
```bash
# Check agent processes
ps aux | grep livekit_agent
# Monitor remote server logs
cd app/remote-server && npm start
# Test Chrome connection
node test-multi-user-livekit.js
```
The system now provides a complete multi-user voice automation experience where each Chrome extension user automatically gets their own dedicated LiveKit agent! 🎉
