The GitLab MCP Server is a TypeScript-based Model Context Protocol server that provides comprehensive GitLab integration for AI assistants, enabling management of projects, issues, merge requests, pipelines, and repositories through natural language commands.

Projects: List and search projects with filtering by ownership, visibility, and search terms; get detailed project information with optional simplified views for token efficiency

Issues: List, view, and create issues with filtering by state, scope, labels, author, and assignee; search by title and description; manage descriptions and milestones

Merge Requests: Complete lifecycle management including listing, creating, and updating MRs; filter by state, author, assignee, scope, and branches; manage title, description, labels, assignees, reviewers, and state (close/reopen); set merge options (auto-merge when pipeline succeeds, squash commits, remove source branch); mark as draft or ready for review

Code Review: Create comments, threaded discussions, and inline code comments; resolve/unresolve discussions

CI/CD Pipelines: List, create, retry, cancel, and delete pipelines with filtering by status, branch, SHA, username, and dates; manage pipeline variables

Jobs & Logs: List jobs within pipelines with status filtering; retrieve full job logs and traces with advanced options (partial logs, tail mode, line limits, raw format)

Repository: List branches with search capability; get commit history with filtering by date range, author, and branch/tag

User Management: Retrieve current authenticated user information

Additional Features: Supports both GitLab.com and self-hosted instances; fully typed TypeScript implementation; pagination support; token-optimized responses

Provides comprehensive integration with GitLab's REST API, enabling interaction with projects, issues, merge requests, pipelines, jobs, branches, commits, and user information. Allows listing, creating, and managing GitLab resources with complete type safety.
