🚀 GoHighLevel MCP Server

🚨 IMPORTANT: FOUNDATIONAL PROJECT NOTICE

⚠️ This is a BASE-LEVEL foundational project designed to connect the GoHighLevel community with AI automation through MCP (Model Context Protocol).

🎯 What This Project Is:

Foundation Layer: Provides access to ALL sub-account level GoHighLevel API endpoints via MCP
Community Starter: Built to get the community moving forward together, faster
Open Architecture: API client and types can be further modularized and segmented as needed
Educational Resource: Learn how to integrate GoHighLevel with AI systems

⚠️ Critical AI Safety Considerations:

Memory/Recall Systems: If you don't implement proper memory or recall mechanisms, AI may perform unintended actions
Rate Limiting: Monitor API usage to avoid hitting GoHighLevel rate limits
Permission Controls: Understand that this provides FULL access to your sub-account APIs
Data Security: All actions are performed with your API credentials - ensure proper security practices

🎯 Intended Use:

Personal/Business Use: Integrate your own GoHighLevel accounts with AI
Development Base: Build upon this foundation for custom solutions
Learning & Experimentation: Understand GoHighLevel API patterns
Community Contribution: Help improve and extend this foundation

🚫 NOT Intended For:

Direct Resale: This is freely available community software
Production Without Testing: Always test thoroughly in development environments
Unmonitored AI Usage: Implement proper safeguards and monitoring

🔑 CRITICAL: GoHighLevel API Setup

📋 Required: Private Integrations API Key

⚠️ This project requires a PRIVATE INTEGRATIONS API key, not a regular API key!

How to get your Private Integrations API Key:

Login to your GoHighLevel account
Navigate to Settings → Integrations → Private Integrations
Create New Private Integration:
- Name: MCP Server Integration (or your preferred name)
- Webhook URL: Leave blank (not needed)
Select Required Scopes based on tools you'll use:
- ✅ contacts.readonly - View contacts
- ✅ contacts.write - Create/update contacts
- ✅ conversations.readonly - View conversations
- ✅ conversations.write - Send messages
- ✅ opportunities.readonly - View opportunities
- ✅ opportunities.write - Manage opportunities
- ✅ calendars.readonly - View calendars/appointments

- ✅ products.write - Manage products
Save Integration and copy the generated Private API Key
Copy your Location ID from Settings → Company → Locations

💡 Tip: You can always add more scopes later by editing your Private Integration if you need additional functionality.

This project was a 'time-taker' but I felt it was important. Feel free to donate - everything will go into furthering this Project -> Aiming for Mass Agency "Agent Driven Operations".

🔐 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
