GHL MCP Server

The only GHL MCP server built and verified against a real sub-account.

90 tools. 16/17 API surfaces live-tested. 16 bugs fixed that ship broken everywhere else. Works in Claude Desktop, Cursor, Windsurf, and VS Code.

Want 5-minute setup, 57 agency prompts, and one-click installer? -> highbridge.pro — $97 founding price

Why this one

Every other GHL MCP has at least one of these problems:

HighBridge:

• 90 tools, every major GHL surface, all working

• 16/17 API surfaces live-verified (reputation requires GHL Reputation Management add-on, clearly documented)

• 16 production bugs found and fixed, see list below

• Native stdio transport, works in Claude Desktop with no middleware

• Actively maintained by a solo GHL operator running it in production daily

The 16 bugs fixed

1. get_appointments: wrong URL path, always 404

2. delete_appointment: IAM 401, missing required field

3. create_appointment / update_appointment: appointmentStatus field rejected by GHL

4. search_contacts: sent as GET, GHL requires POST

5. create_contact_task: missing required completed field

6. move_opportunity_stage: PATCH 404, GHL requires PUT

7. Custom fields path: 403 on wrong endpoint

8. Email templates: wrong endpoint (/emails/templates -> /emails/builder)

9. Email campaigns: wrong endpoint (/emails/campaigns -> /emails/schedule)

10. Payments: missing altId/altType params, returns empty

11. create_invoice: required fields missing, fails silently

12. send_invoice: missing userId, silently fails

13. get_contacts / get_opportunities: pagination off-by-one, drops last page

14. get_form_submissions: wrong page param name

15. get_social_posts: GET endpoint, GHL requires POST

16. trigger_workflow: timestamp format rejected (must be +00:00 not Z)

Tools (90 total)

Setup

1. Get your GHL Private Integration Token

GHL → Settings → Integrations → API Keys → Create Private Integration → check all scopes → copy key (starts with pit-).

2. Get your Location ID

It's in the URL when inside a sub-account: https://app.gohighlevel.com/location/YOUR_LOCATION_ID/...

3. Install

git clone https://github.com/centrender/highbridge-ghl-mcp.git
cd highbridge-ghl-mcp
npm install
cp .env.example .env
# Add your GHL_API_KEY and GHL_LOCATION_ID to .env

4. Verify it works

node src/index.js --test

17 live API surface checks fire against your GHL account. Expect 16 green. Reputation shows red if you don't have the GHL Reputation Management add-on, everything else should pass.

5. Connect to Claude Desktop

Mac: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "highbridge": {
      "command": "node",
      "args": ["/absolute/path/to/highbridge-ghl-mcp/src/index.js"],
      "env": {
        "GHL_API_KEY": "pit-your-key-here",
        "GHL_LOCATION_ID": "your-location-id-here"
      }
    }
  }
}

Restart Claude Desktop. Tools appear automatically.
