概要

What is GitLab MCP Server?

The GitLab MCP Server is a typed, paginated, schema-validated bridge from the Model Context Protocol (MCP) to the GitLab REST API, exposing 86 tools for AI agents. It works with gitlab.com or any self-hosted GitLab instance and authenticates via personal access token, OAuth Bearer token, or read‑only mode.

How to use GitLab MCP Server?

Install and run with npx -y @yoda.digital/gitlab-mcp-server or the Docker image ghcr.io/yoda-digital/mcp-gitlab-server. Configure environment variables GITLAB_PERSONAL_ACCESS_TOKEN and GITLAB_API_URL (default https://gitlab.com/api/v4). Add the server to your MCP client config (e.g., claude_desktop_config.json) as a subprocess. For remote deployments, run the HTTP service with AUTH_MODE=oauth and front it with a gateway.

Key features of GitLab MCP Server

Works with GitLab SaaS and self‑hosted instances.
Authentication modes: PAT, OAuth per connection, read‑only.
Supports stdio, legacy SSE, and Streamable HTTP transports.
Read‑only mode hides all mutating tools at registration.
Docker image and Helm chart with security hardening.

Use cases of GitLab MCP Server

AI coding assistant managing merge requests, pipelines, and code reviews.
Automated CI/CD monitoring and incident response via agent workflows.
Developer querying project wikis, issues, and commit history in natural language.
Shared OAuth‑gated MCP gateway for an entire DevOps team.
Safe demo or exploration with read‑only access enforced at tool registration.

よくある質問

How does this compare to other GitLab MCP servers?

GitLab’s built‑in MCP server offers 15 tools and requires GitLab Premium/Ultimate. `zereight/gitlab-mcp` has broader auth surface and more tools. `mcpland/gitlab-mcp` focuses on a policy‑engine. This server provides 86 tools with PAT, OAuth, and read‑only modes, and runs on any GitLab instance.

What runtime does the server require?

The server runs on Node.js (published as an npm package) or as a Docker container based on `node:24-alpine`. The Docker image runs as non‑root (uid 1000) with all capabilities dropped.

Can the server be used in read‑only mode?

Yes. Set `GITLAB_READ_ONLY_MODE=true` to filter every mutating tool out at registration time. A misbehaving agent cannot see or call write tools.

What transport protocols are supported?

Three transports: stdio (default for local clients), legacy SSE (`USE_SSE=true`), and Streamable HTTP (`USE_STREAMABLE_HTTP=true`). Streamable HTTP provides `POST /mcp`, `GET /mcp`, `DELETE /mcp`, and a `/healthz` endpoint.

How does authentication work for remote deployments?

Remote HTTP deployments must use `AUTH_MODE=oauth` (the server refuses to start with PAT mode on a non‑loopback bind). Each MCP connection brings its own `Authorization: Bearer <token>`, which the server forwards as the effective PAT for that connection.
