🚀 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:

1. Login to your GoHighLevel account

2. Navigate to Settings → Integrations → Private Integrations

3. Create New Private Integration:

• Name: MCP Server Integration (or your preferred name)
• Webhook URL: Leave blank (not needed)

4. 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
• ✅ calendars.write - Create/manage appointments
• ✅ locations.readonly - View location data
• ✅ locations.write - Manage location settings
• ✅ workflows.readonly - View workflows
• ✅ campaigns.readonly - View campaigns
• ✅ blogs.readonly - View blog content
• ✅ blogs.write - Create/manage blog posts
• ✅ users.readonly - View user information
• ✅ custom_objects.readonly - View custom objects
• ✅ custom_objects.write - Manage custom objects
• ✅ invoices.readonly - View invoices
• ✅ invoices.write - Create/manage invoices
• ✅ payments.readonly - View payment data
• ✅ products.readonly - View products
• ✅ products.write - Manage products

5. Save Integration and copy the generated Private API Key

6. 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.

🔐 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:

1. Verify MCP configuration syntax

2. Check file paths are absolute

3. Ensure environment variables are set

4. 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
