# 🚀 GitLab MR MCP

A Model Context Protocol (MCP) server for interacting with GitLab merge requests and issues.

## 📌 Overview

This project implements a server using the Model Context Protocol (MCP) that allows AI agents to interact with GitLab repositories. It provides tools for:

- Listing available GitLab projects
- Fetching merge request details and comments
- Getting merge request diffs
- Adding comments to merge requests
- Adding line-specific comments to code in merge request diffs
- Fetching issue details
