🎯 Quick Test Your Deployment

Once deployed, test these endpoints:

Health Check:

GET https://your-domain.com/health

Should return:

{
  "status": "healthy",
  "server": "ghl-mcp-server",
  "tools": { "total": 21 }
}

Tools List:

GET https://your-domain.com/tools

Should return all 21 MCP tools.

SSE Endpoint (for ChatGPT):

GET https://your-domain.com/sse

Should establish Server-Sent Events connection.

🔗 Connect to ChatGPT

Once your server is deployed:

1. Open ChatGPT Desktop App

2. Go to: Settings → Beta Features → Model Context Protocol

3. Add New Connector:

   • Name: GoHighLevel MCP
   • Description: Connect to GoHighLevel CRM
   • MCP Server URL: https://your-domain.com/sse
   • Authentication: OAuth (or None if no auth needed)

4. Save and Connect

🚨 Troubleshooting

Common Issues:

1. 502 Bad Gateway:

   • Check environment variables are set
   • Verify GHL API key is valid
   • Check server logs for errors

2. CORS Errors:

   • Server includes CORS headers for ChatGPT
   • Ensure your domain is accessible

3. Connection Timeout:

   • Free tier platforms may have cold starts
   • First request might be slow

4. SSE Connection Issues:

   • Verify /sse endpoint is accessible
   • Check browser network tab for errors

Debug Commands:

# Check server status
curl https://your-domain.com/health

# Test tools endpoint
curl https://your-domain.com/tools

# Check SSE connection
curl -H "Accept: text/event-stream" https://your-domain.com/sse
