Gitlab MCP Server

Open source GitLab MCP server for AI assistants: 2-tool dynamic find/execute over 860+ GitLab actions (1,000+ Enterprise), stdio/HTTP/OAuth, safe/read-only modes.

What the server does

You talk to your AI assistant; it does the GitLab work. No project IDs, API endpoints, or JSON to remember.

• 🗣️ Plain-language GitLab. The AI translates "is MR !15 safe to merge?" into the right API calls. You don't touch endpoints, IDs, or JSON
• 🪶 Low-token by default. The default dynamic surface exposes just 2 tools (find + execute) while reaching the full catalog — so it fits any client's context window. (Token footprint →)
• ✅ Proven with real models. An automated evaluator runs Anthropic, Google, OpenAI, and Qwen against live GitLab instances: 99.5% aggregate success across thousands of operations. (Results →)
• 🔒 Safe by design. Read-only mode, safe mode (dry-run preview of every mutation), TLS options for self-hosted GitLab, and continuous SonarCloud quality/security gates
• 🖥️ Runs anywhere. One static binary or container; Windows, Linux & macOS; amd64 & arm64; stdio (desktop) and HTTP (remote)
• 45 MCP resources — (read-only data: projects, issues, pipelines, MRs, branches, members, the surface-aware gitlab://tools manifest, and workflow best-practice guides)
