GoHighLevel MCP 2026

Talk to GoHighLevel. Get the work done.

Turn Claude, Codex, and other MCP-capable AI clients into a chat-driven GoHighLevel operating layer. Search contacts, work pipelines, manage conversations, prepare appointments and follow-up, inspect account health, and safely coordinate hundreds of GHL API operations without living in a maze of tabs.

• 927 MCP tools across the full registry

• 100% of the locked current v3 endpoint surface covered (661 / 661)

• Curated agent workflows for useful outcomes instead of raw endpoint hunting

• Confirmation gates before consequential CRM writes

• stdio, Streamable HTTP, legacy SSE, and optional MCP Apps

This is the open-source GHL control layer for chat. Source: https://github.com/fs-solver-3/GoHighLevel-MCP

What it covers

The repository includes an optional private/unstable internal workflow-builder surface that requires separate browser-derived authentication. It is not the same thing as a dependable public GHL API. The MCP tells compatible AI clients about that boundary during initialization so they stop promising native workflow construction.

New here? Start with QUICKSTART.md.

Using an AI/dev agent? Give it AGENT_SETUP.md and say: "Set this up for my MCP client using the curated profile. Ask me for credentials if needed. Do not run write tools."

5-Minute Quickstart

Requirements:

• Node 20+

• A GoHighLevel private integration token or OAuth access token

• A GoHighLevel Location ID

npm install
cp .env.example .env
npm run build
npm run doctor
npm run configure:codex

Add your credentials to .env:

GHL_API_KEY=your_private_integration_api_key
GHL_LOCATION_ID=your_location_id
GHL_BASE_URL=https://services.leadconnectorhq.com
GHL_API_VERSION=v3
GHL_API_GENERATION=v3
# GHL_USER_TYPE=Location # or Company; optional access preflight

GHL_API_VERSION=v3 is the current named HighLevel API Version header, not a date. Routing is per endpoint: ad-publishing remains mostly on 2021-07-28; Conversations use v3 in current mode and 2021-04-15 in legacy v2 mode. Set GHL_API_GENERATION=v2 for the legacy surface; the starter GHL_API_VERSION=v3 value is then replaced by the 2023-02-21 fallback. See docs/V3-MIGRATION.md.

Then verify live auth:

npm run auth-check

Setup Commands

npm run setup                 # Create .env if needed, build, and print next steps
npm run first-run             # One-command beginner setup/readiness flow
npm run connect               # Setup plus client config generation
npm run ready                 # Fast readiness check
npm run demo                  # Print MCP Apps demo preview instructions
npm run explain-error -- "Location is not active"
npm run doctor                # Human-readable setup check
npm run doctor -- --json      # Agent-readable setup check
npm run agent:check           # Safe validation for AI/dev agents
npm run auth-check            # Read-only GHL token/location check

Missing credentials are reported as needsHumanAction, not as a broken install. This lets agents build and configure the repo without inventing secrets.

MCP Client Config

Beginner configs use GHL_TOOL_PROFILE=curated so agents see the high-level workflow tools first.

npm run configure:codex
npm run configure:claude
npm run configure:cursor
npm run configure:windsurf

Advanced examples:

node scripts/ghl-mcp.mjs configure codex --profile stable
node scripts/ghl-mcp.mjs configure codex --profile full
node scripts/ghl-mcp.mjs configure codex --profile curated --json

Tool Profiles

• curated - recommended for agents; high-level CRM workflows with confirmation queues.

• stable - production-friendly; official, supplemental, curated, and legacy-compatible tools.

• full - everything.

• official - official OpenAPI and live-docs supplemental tools.

• raw - endpoint-level tools only.

Run

npm run start:stdio       # Desktop MCP clients
npm run start:http        # Streamable HTTP at /mcp
npm run start:legacy      # Legacy SSE at /sse

HTTP also exposes:

• GET /health

• GET /capabilities

• GET /tools

• POST /execute

• POST /tools/call

MCP Apps

npm run apps:setup
npm run apps:preview

Open http://localhost:3001/preview. Without GHL credentials, the apps use preview/demo states and tell you exactly which env vars are missing.

Tool Discovery

npm run tools:list
npm run tools:list -- --search contacts
npm run tools:list -- --category contacts
npm run tools:list -- --stability official
npm run tools:list -- --access write
npm run tools:list -- --destructive
npm run tools:explorer

The static explorer is docs/tool-explorer.html.

Full Registry CLI

The package also exposes every visible MCP tool through the schema-driven ghl command. The CLI reads the live registry, so generated API refreshes do not require hand-written subcommands.

npm link
ghl tools --search contacts --json
ghl describe get_contact --json
ghl get_contact --contact-id CONTACT_ID --dry-run
ghl get_contact --contact-id CONTACT_ID

Tool calls accept schema-aware flags, JSON, files, or stdin and emit JSON by default. All write/delete tools require --confirm; --dry-run validates and resolves any call without contacting GHL. Use --env-file or GHL_ENV_FILE to keep location-specific credentials outside the repository.

See docs/CLI.md for installation, discovery, input formats, safety behavior, and agent usage.

High-Level Agent Tools

Start agents with the curated profile and prefer these high-level tools before raw endpoints:

• crm_location_overview

• crm_daily_briefing

• crm_search_everything

• crm_next_best_actions

• crm_get_next_page

• crm_workflow_automation_options — explains the native workflow boundary and the next steps inside it.

• crm_prepare_contact_followup

• crm_prepare_lead_reactivation

• crm_prepare_missed_call_response

• crm_prepare_pipeline_cleanup

• crm_prepare_review_request_batch

• crm_prepare_invoice_followup

Update History

API Coverage

• Official endpoint references parsed: 1221 (v3 repo: 627, v2 repo: 590, current live-docs v3: 4)

• Current/default v3 coverage: 661 / 661 (100%)

• Legacy v2 compatibility coverage: 590 / 590 (100%)

• Dual-generation union coverage: 681 / 681 (100%)

• Generated official endpoint tools: 543

• MCP tools in the full registry: 927

• Local-only endpoint references: current v3 265; dual-generation union 245

The scanner reads both the v2 (apps/*.json) and v3 (apps/v3/*-v3.json) OpenAPI fragments. v3 endpoints are the source of truth; superseded v2 entries are retained for GHL_API_GENERATION=v2 legacy mode.

Safety

• .env is ignored and must never be committed.

• test-tool refuses write/destructive tools unless --confirm is supplied.

• Curated workflow tools stage confirmation queues for writes.

• Use curated for beginners and stable for production.
