The GitLab MCP server acts as a crucial bridge for integrating Large Language Models (LLMs) with GitLab instances, offering powerful capabilities for exploration, analysis, and automation. It provides a GraphQL-first interface with automatic schema discovery, supporting both cloud and self-hosted GitLab deployments. Recently updated for enhanced compatibility and stability with platforms like LibreChat, this server ensures secure, per-session credential isolation and a streamable HTTP transport, making it an ideal tool for LLMs to interact with GitLab's vast data, from codebases to issues and merge requests.
