## Description

The GitLab MCP for Code Review server enables AI assistants like Claude to interact directly with GitLab's merge requests through the GitLab API. Built on FastMCP and adapted from a Gerrit code review implementation, this Python-based server provides tools for analyzing merge requests, viewing file diffs, comparing versions, managing reviews, and retrieving project information. It handles authentication via GitLab personal access tokens and includes robust error handling for API requests. The implementation is particularly valuable for developers seeking AI assistance with code reviews without leaving their workflow, allowing assistants to fetch complete merge request details, add comments, approve changes, and analyze code differences across branches or commits.
