Gitlab MCP Server

What is GitLab MCP Server?

A Model Context Protocol (MCP) server that allows AI assistants (like Claude) to interact with GitLab repositories. It provides comprehensive capabilities for managing projects, issues, merge requests, comments, labels, milestones, time tracking, and more. This enhanced implementation includes additional endpoints and improved error handling compared to the original MCP GitLab server.

How to use GitLab MCP Server?

Install globally (npm install -g @piatra-open-source/gitlab-mcp-server) or as a project dependency. Set the required environment variable GITLAB_PERSONAL_ACCESS_TOKEN (and optionally GITLAB_API_URL for self-managed instances). Run the server with gitlab-mcp-server or embed it in your application using the Node.js child process API.
