About This MCP

ARCHIVED: Former Anthropic reference MCP server for GitLab (merge requests, CI/CD pipelines, issues), archived 2025-05-29 to servers-archived and no longer maintained; no security guarantees for archived servers. GitLab now ships an OFFICIAL built-in MCP server (experiment in GitLab 18.3, beta since 18.6) at https://<gitlab-instance>/api/v4/mcp with OAuth 2.0 Dynamic Client Registration; it requires GitLab Duo and a Premium/Ultimate tier and should be preferred.
