Calendar Sync Integration

This MCP server is specifically designed to work seamlessly with calendar synchronization systems:

Google Calendar Sync Compatibility

• Meeting entities include googleEventId field for sync tracking
• User lookup by email for attendee management
• Date range filtering for efficient sync operations
• Attendee linking through contactsIds and usersIds

Sync Prevention Features

• Comprehensive entity tracking to prevent duplicate creation
• Support for external system identifiers
• Robust error handling for sync operations

Workflow Integration

// Typical calendar sync workflow
const existingMeetings = await client.callTool('search_meetings', {
  dateFrom: syncStartDate,
  dateTo: syncEndDate
});

const user = await client.callTool('get_user_by_email', {
  emailAddress: assignedUserEmail
});

// Create meetings from external calendar
for (const externalEvent of externalEvents) {
  await client.callTool('create_meeting', {
    name: externalEvent.title,
    dateStart: externalEvent.start,
    dateEnd: externalEvent.end,
    googleEventId: externalEvent.id,
    description: externalEvent.description
  });
}

Troubleshooting

Common Issues

Connection Failures

# Test basic connectivity
node test-connection.js

# Check environment variables
npm run test:config

# Test specific endpoints
curl -H "X-Api-Key: YOUR_API_KEY" http://your-espocrm.com/api/v1/App/user

Authentication Issues

• Verify API key is correct and active
• Check user permissions in EspoCRM
• Ensure API access is enabled for the user
• Verify the correct API endpoint format

Meeting Creation Issues

• Ensure required fields (name, dateStart, dateEnd) are provided
• Verify date format is ISO 8601 (YYYY-MM-DDTHH:mm:ss)
• Check user permissions for meeting creation
• Validate contact and user IDs exist before linking

User Search Issues

• Verify user has permission to access User entity
• Check if users exist in the system
• Ensure email addresses are correctly formatted

Debug Mode

Enable debug logging:

LOG_LEVEL=debug

View detailed logs:

tail -f logs/espocrm-mcp.log

Connection Diagnostics

Test specific API endpoints:

# Test user endpoint
curl -H "X-Api-Key: YOUR_KEY" http://your-espocrm.com/api/v1/App/user

# Test meeting search
curl -H "X-Api-Key: YOUR_KEY" "http://your-espocrm.com/api/v1/Meeting?maxSize=1"

# Test user search  
curl -H "X-Api-Key: YOUR_KEY" "http://your-espocrm.com/api/v1/User?maxSize=1"

Performance Considerations

Pagination

• Default limit: 20 results
• Maximum limit: 200 results
• Use offset for pagination through large datasets

Rate Limiting

• Default: 100 requests per minute
• Configurable via RATE_LIMIT environment variable
• Implements exponential backoff for rate limit handling

Caching

• No built-in caching (recommended to implement at application level)
• EspoCRM API responses are not cached to ensure data freshness

Bulk Operations

• Individual entity operations only
• For bulk operations, iterate through arrays at the application level
• Consider rate limiting when processing large datasets

Security Best Practices

API Key Management

• Store API keys in environment variables only
• Rotate API keys regularly
• Use dedicated API users with minimal required permissions
• Monitor API usage logs

Network Security

• Use HTTPS for all EspoCRM connections
• Consider VPN or private networks for sensitive data
• Implement IP whitelisting if supported by your EspoCRM instance

Data Validation

• All inputs are validated using Zod schemas
• Sanitization is applied to prevent injection attacks
• Error messages do not expose sensitive system information
