Solo IDE

Claude Code (recommended)

claude mcp add gitlab \
  --env GITLAB_URL=https://gitlab.com \
  --env GITLAB_TOKEN=glpat-your-pat \
  -- npx -y @ttpears/gitlab-mcp-server

--scope controls where the configuration lives:

• --scope local (default) — only this user, only this project
• --scope user — shared across all of your projects
• --scope project — written to .mcp.json in the project root, intended for team check-in

For team check-in, use a ${VAR} placeholder so the PAT itself stays out of git:

{
  "mcpServers": {
    "gitlab": {
      "command": "npx",
      "args": ["-y", "@ttpears/gitlab-mcp-server"],
      "env": {
        "GITLAB_URL": "https://gitlab.com",
        "GITLAB_TOKEN": "${GITLAB_TOKEN}"
      }
    }
  }
}

Each contributor exports GITLAB_TOKEN in their shell; Claude Code expands it on launch.

Cold start

If launching via npx adds noticeable latency, install once:

npm install -g @ttpears/gitlab-mcp-server

…and replace npx -y @ttpears/gitlab-mcp-server with gitlab-mcp-server in your config.

Claude Desktop

Add to claude_desktop_config.json:

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

LibreChat — service-account reads

A read-only service token covers reads (so anyone in the workspace can ask questions). Each user supplies their own PAT for writes through LibreChat's customUserVars.

LibreChat's documented extension point is docker-compose.override.yml — the fragments below assume you're adding gitlab-mcp there alongside LibreChat's own api, mongodb, etc.

.env

GITLAB_URL=https://gitlab.example.com
GITLAB_READ_TOKEN=glpat-readonly-service-token   # read_api scope only

Use https://gitlab.com for SaaS GitLab; use your own host for self-hosted.

docker-compose.override.yml

services:
  gitlab-mcp:
    image: ghcr.io/ttpears/gitlab-mcp:1.14.0
    env_file:
      - .env
    networks:
      - librechat
    restart: unless-stopped

env_file reads GITLAB_URL and GITLAB_READ_TOKEN from .env. No port mapping needed — LibreChat's api container reaches gitlab-mcp over the shared librechat network. Add ports: ["8008:8008"] only if you need to hit it from the host (e.g. for curl http://localhost:8008/health).

Then:

docker compose -f docker-compose.yml -f docker-compose.override.yml up -d gitlab-mcp api

api is restarted alongside so it re-reads librechat.yaml.

librechat.yaml

mcpServers:
  gitlab:
    type: streamable-http
    url: http://gitlab-mcp:8008/
    startup: false                # don't connect until the user supplies their PAT
    initTimeout: 30000
    timeout: 120000
    headers:
      Authorization: "Bearer {{GITLAB_PAT}}"
      X-GitLab-Url: "{{GITLAB_URL_OVERRIDE}}"   # optional; lets a user point at a different GitLab
    customUserVars:
      GITLAB_PAT:
        title: "GitLab Personal Access Token"
        description: "Your GitLab PAT with api scope. Used for issues, MRs, and comments you create or edit."
      GITLAB_URL_OVERRIDE:
        title: "GitLab URL (optional)"
        description: "Leave blank to use the workspace default. Override only if your account is on a different GitLab instance."
