This document provides a comprehensive reference for all MCP tools available in the Laravel Healthcare MCP Server, organized by authentication type and functionality.

**Last Updated**: ${new Date().toISOString().split('T')[0]}  
**Total Tools**: ${totalTools}  
**API Coverage**: 100% from api-docs.json comprehensive audit

## 📋 Tool Distribution by Authentication Type

| Authentication Type | Tool Count | Description |
|-------------------|------------|-------------|
| **Public** | ${this.toolStats.public || 0} | Login, registration, password management, webhooks |
| **Provider** | ${this.toolStats.provider || 0} | Clinical data, EMR operations, patient management |
| **Patient** | ${this.toolStats.patient || 0} | Patient portal operations |
| **Partner** | ${this.toolStats.partner || 0} | Partner business operations |
| **Affiliate** | ${this.toolStats.affiliate || 0} | Affiliate management |
| **Network** | ${this.toolStats.network || 0} | Network operations |

### Basic Tool Usage
\`\`\`javascript
// Public tool (no authentication)
await mcpClient.callTool('public_post_login', {
  email: 'user@example.com',
  password: 'password123'
});

// Provider tool (requires authentication)
await mcpClient.callTool('provider_get_emrpatientslist', {
  draw: 1,
  start: 0,
  length: 10
});
\`\`\`

### New Video Call Features
\`\`\`javascript
// Start a video call
await mcpClient.callTool('provider_post_startcall', {
  patient_id: 123,
  agent_id: 456,
  appointment_id: 789,
  call_type: 'consultation'
});

// Join a meeting
await mcpClient.callTool('provider_get_joinmeeting', {
  meeting_id: 'meeting-123'
});
\`\`\`

## 🔒 Security Notes

- **Public Tools**: No authentication required, rate-limited
- **Provider Tools**: Require provider authentication, HIPAA-compliant
- **Patient Tools**: Require patient authentication, access to own data only
- **Partner/Affiliate/Network Tools**: Require respective authentication levels
