GitLab MCP Server

All of GitLab for your AI assistant. Up to 1,106 actions over GitLab's REST and GraphQL APIs, from Free to Ultimate and on GitLab.com, in one self-contained binary that works with Claude, Cursor, VS Code, Codex and any other MCP client. You ask in plain language; it does the GitLab work.

11,396 tokens of startup context by default, the same on every GitLab tier (1,994 with GITLAB_MCP_CAPABILITY_SURFACE=minimal). Two tools reach the whole catalog, where listing every tool as its own costs from 565,889 to 723,949 tokens. Measured with the cl100k_base tokenizer and checked in CI. How it is measured

"Review merge request !15: is it safe to merge?" · "Why did the last pipeline fail?" · "List open issues assigned to me" · "Generate release notes from v1.0 to v2.0"

Why this server

• Every tier and every instance. Free/CE, Premium and Ultimate, self-managed or GitLab.com with its Orbit knowledge graph. The tier is detected and the catalog follows it.

• The token you already have. A personal, project or group access token with api, or read_api for the actions GitLab accepts from it; a fine-grained token, judged action by action from its grant; OAuth in HTTP mode. Each action's tool reference entry says which scope and which fine-grained permissions it needs.

• Guard rails. Read-only mode, safe mode (a preview of each write instead of the write), tools excluded by name, and a confirmation before anything destructive.

• Three surfaces, two transports. Two discovery tools by default, one tool per domain or one per action; stdio for a desktop client, or HTTP for a shared deployment that keeps each credential apart. 45 resources and 37 prompts besides.

• Releases you can verify. Signed checksums, an SBOM per binary and build provenance for every artifact.

Install

The buttons register the Docker image, so they need Docker; the Claude Desktop row downloads a native extension instead. Create a personal access token with the api scope (or read_api for the actions GitLab accepts from it; add GITLAB_MCP_READ_ONLY=true when nothing may be written).

Claude Code. The registration command never carries the token: -e GITLAB_TOKEN forwards it from the environment Claude Code hands docker.

export GITLAB_TOKEN=glpat-xxxx
claude mcp add gitlab --transport stdio \
  -- docker run -i --rm -e GITLAB_TOKEN ghcr.io/jmrplens/gitlab-mcp-server:latest

Any other client runs one of these as the server's command, with GITLAB_TOKEN in the environment it passes:

npx -y @jmrp.io/gitlab-mcp-server                   # npm, nothing installed first
uvx jmrplens-gitlab-mcp-server                      # PyPI, nothing installed first
dnx gitlab-mcp-server                               # NuGet (.NET 10 SDK), nothing installed first
brew install jmrplens/tap/gitlab-mcp-server         # Homebrew, macOS and Linux
winget install --id jmrplens.gitlab-mcp-server -e   # winget, Windows
docker run -i --rm -e GITLAB_TOKEN ghcr.io/jmrplens/gitlab-mcp-server:latest

For a self-managed instance, set GITLAB_URL=https://gitlab.example.com beside the token; with the Docker image, also forward it by adding -e GITLAB_URL to the docker arguments, since the container receives only the variables named there (Docker install). Every channel, per-client configuration and verification step is in the installation guide, and an assistant installing it for you will find the same in llms.txt.

To try it first, a public instance runs at https://mcp.jmrp.io/gitlab, and the browser inspector calls it read-only after an OAuth sign-in. Your token and every request pass through that machine, so run it yourself to keep using it; the hosted endpoint page says what it is and is not.
