What is the GitLab MCP server?

The GitLab MCP (.NET) is a Model Context Protocol (MCP) server specifically designed to connect AI clients with GitLab resources, such as projects, merge requests, and issues, using streamable HTTP transport. It enables AI-powered interactions with your GitLab environment.

How does this tool facilitate AI integration with GitLab?

It exposes a streamable HTTP MCP endpoint at `/api/mcp`, allowing AI clients to make requests and receive responses for managing GitLab entities. This standardized protocol enables AI to retrieve information and perform actions like commenting on merge requests or fetching project details.

Is the GitLab MCP server compatible with popular AI development tools?

Yes, it is designed for compatibility with various MCP clients. Configuration examples are provided for tools like VS Code (MCP Extension), Codex CLI, GitHub Copilot, and Google Antigravity, making it easy to integrate into your existing AI development workflow.

How does the GitLab MCP server handle authentication?

Authentication for the MCP server itself is handled via an `MCP_SERVER_API_KEY` (Bearer or `X-API-Key`). For accessing GitLab, it prioritizes `X-GitLab-Token` (or similar headers) from the client request, falling back to the `GITLAB_TOKEN` environment variable if no client-provided token is present.

What GitLab resources can be managed using this MCP server?

The server provides tools for interacting with GitLab projects (e.g., `get_projects`), merge requests (e.g., `list_open_merge_requests`, `add_merge_request_comment`, `approve_merge_request`), and issues (e.g., `get_issue_details`).

Provides a Model Context Protocol (MCP) server for GitLab, enabling AI clients to interact with GitLab resources via streamable HTTP.

This project implements a Model Context Protocol (MCP) server specifically designed for GitLab, built on .NET 9.0. It facilitates seamless communication between AI clients and GitLab's ecosystem through a streamable HTTP transport, allowing AI models to programmatically access and manipulate projects, merge requests, and issues. The server prioritizes secure interactions with configurable API keys and flexible GitLab authentication mechanisms, making it a robust bridge for integrating AI-powered workflows into GitLab-centric development environments.
