🔌 Claude Desktop Integration

Configuration

Add to your Claude Desktop MCP settings file:

Location: ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "ghl": {
      "command": "npx",
      "args": [
        "/absolute/path/to/ghl-mcp-server-moose-v1/dist/stdio-server.js"
      ],
      "env": {
        "GHL_API_KEY": "your_private_integrations_api_key",
        "GHL_LOCATION_ID": "your_location_id"
      }
    }
  }
}

Important Notes:

Use absolute paths - Replace /absolute/path/to/ with your actual project path
Executable permissions - Ensure stdio-server.js has execute permissions:
```
chmod +x dist/stdio-server.js
```
Restart Claude - Completely quit and restart Claude Desktop after configuration changes
Check logs - If connection fails, check: ~/Library/Logs/Claude/mcp*.log

🔐 Security & Best Practices

Environment Security

✅ Never commit API keys to version control
✅ Use environment variables for all sensitive data
✅ Implement proper CORS policies
✅ Regular API key rotation
✅ Monitor API usage and rate limits

Production Considerations

✅ Implement proper error handling and logging
✅ Set up monitoring and alerting
✅ Use HTTPS for all deployments
✅ Implement request rate limiting
✅ Regular security updates

API Rate Limiting

GoHighLevel API has rate limits
Implement exponential backoff
Cache frequently requested data
Use batch operations when available

🚨 Troubleshooting Guide

Common Issues & Solutions

Build Failures:

# Clear cache and reinstall
rm -rf node_modules package-lock.json dist/
npm install
npm run build

API Connection Issues:

# Test API connectivity (use your Private Integrations API key)
curl -H "Authorization: Bearer YOUR_PRIVATE_INTEGRATIONS_API_KEY" \
     https://services.leadconnectorhq.com/locations/YOUR_LOCATION_ID

Common API Issues:

✅ Using Private Integrations API key (not regular API key)
✅ Required scopes enabled in Private Integration
✅ Location ID matches your GHL account
✅ Environment variables properly set

Claude Desktop Integration:

Verify MCP configuration syntax
Check file paths are absolute
Ensure environment variables are set
Restart Claude Desktop after changes

Memory Issues:

# Increase Node.js memory limit
node --max-old-space-size=8192 dist/server.js

CORS Errors:

Configure CORS_ORIGINS environment variable
Ensure proper HTTP headers
Check domain whitelist

Performance Optimization

Enable response caching for read operations
Use pagination for large data sets
Implement connection pooling
Monitor memory usage and optimize accordingly
