Which integrations are available for this server?

Provides comprehensive GitLab integration with search across projects, issues, merge requests, users, and groups; code exploration and file browsing; issue and merge request management (create, update); and support for custom GraphQL queries with automatic schema discovery. Supports both GitLab.com and self-hosted instances. Enables execution of custom GraphQL queries against GitLab's API with automatic schema introspection and discovery of available operations.

How do I use GitLab MCP Server?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@GitLab MCP Server search for open issues in the 'web-app' project" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

GitLab MCP Server

npm version License: MIT

A community MCP server for GitLab — works with any GitLab tier (Free, Premium, Ultimate), no GitLab Duo required.

How This Differs from GitLab's Official MCP Server

GitLab ships an official MCP server (Beta) that requires Premium/Ultimate and GitLab Duo with beta features enabled. This community server is an alternative for teams that don't have those requirements or need different capabilities.

	This server	GitLab official
GitLab tier	Free, Premium, Ultimate	Premium / Ultimate only
GitLab Duo required	No	Yes
Auth	Personal Access Token	OAuth 2.0 Dynamic Client Registration
Transport	stdio + streamable HTTP	stdio (via `mcp-remote`) + HTTP
Multi-client	Claude Code, LibreChat, any MCP client	Claude Desktop, Claude Code, Cursor, VS Code
Multi-user auth modes	hybrid / shared / per-user	OAuth per-user
GraphQL schema discovery	Yes — introspect & run custom queries	No
Repository browsing & file reading	Yes	No
User / group search	Yes	No
Update issues & MRs	Yes	No (create only)
CI/CD pipeline management	Yes	Yes
MR diffs & commits	Yes	Yes
Work item notes	Yes	Yes
Semantic code search	No	Yes (requires additional setup)
Label search	Yes	Yes
Milestone tracking	Yes	No
Iteration/sprint tracking	Yes	No
Time tracking & timelogs	Yes	No
MR reviewer & approval status	Yes	No
Project statistics dashboard	Yes	No
Group member listing	Yes	No

Choose this server if you're on GitLab Free/Community Edition, need GraphQL flexibility, want repo browsing, or run LibreChat multi-user deployments.

Choose the official server if you have GitLab Premium/Ultimate with Duo, need semantic code search, or prefer OAuth over PATs.

Quick Start

1. Create a GitLab Token

Go to GitLab → User Settings → Access Tokens → create a token with read_api (read-only) or api (full access) scope.

2. Choose Your Client

Claude Code — stdio transport, single-user
LibreChat (Docker) — streamable HTTP, multi-user with per-user auth

Claude Code

Add to your Claude Code settings (.claude/settings.json or project .mcp.json):

{
  "mcpServers": {
    "gitlab": {
      "command": "npx",
      "args": ["-y", "@ttpears/gitlab-mcp-server"],
      "env": {
        "GITLAB_URL": "https://gitlab.com",
        "GITLAB_SHARED_ACCESS_TOKEN": "glpat-your-token-here"
      }
    }
  }
}

Restart Claude Code to load the server.

LibreChat (Docker)

Runs as a sidecar container using streamable HTTP transport for multi-user deployments with per-user credential isolation.

1. Add environment variables to your LibreChat `.env`:

GITLAB_URL=https://gitlab.com
GITLAB_AUTH_MODE=hybrid
GITLAB_SHARED_ACCESS_TOKEN=glpat-your-shared-token
GITLAB_MCP_PORT=8008
MCP_TRANSPORT=http

2. Add the service to `docker-compose.override.yml`:

services:
  gitlab-mcp:
    build:
      context: .
      dockerfile: Dockerfile.mcp-gitlab
    env_file:
      - .env
    ports:
      - "8008:8008"
    networks:
      - librechat
    restart: unless-stopped

Copy the Dockerfile from this repo into your LibreChat directory as Dockerfile.mcp-gitlab. It clones and builds from this repository automatically — no source files needed.

3. Configure in `librechat.yml`:

mcpServers:
  gitlab:
    type: streamable-http
    url: "http://gitlab-mcp:8008/"
    headers:
      Authorization: "Bearer {{GITLAB_PAT}}"
      X-GitLab-Url: "{{GITLAB_URL_OVERRIDE}}"
    customUserVars:
      GITLAB_PAT:
        title: "GitLab Personal Access Token"
        description: "PAT with api scope"
      GITLAB_URL_OVERRIDE:
        title: "GitLab URL (optional)"
        description: "e.g., https://gitlab.yourdomain.com"

4. Restart LibreChat:

docker compose down && docker compose -f docker-compose.yml -f docker-compose.override.yml up -d

Troubleshooting

Connection issues with LibreChat:

Verify type: streamable-http in librechat.yml (not sse)
URL should be http://gitlab-mcp:8008/ (the Docker service name, not localhost)
Ensure both containers share the same Docker network
Check logs: docker logs gitlab-mcp

Authentication errors:

Verify token has read_api or api scope and hasn't expired
For LibreChat: check the user provided a valid PAT in the credentials UI

Schema introspection failed:

Requires GitLab 12.0+ with GraphQL API enabled
Verify GITLAB_URL is reachable from the container

Debug logging:

NODE_ENV=development GITLAB_URL=https://your-gitlab.com npm start

Health check (HTTP mode):

curl http://localhost:8008/health
