Custom GitLab MCP Server

Custom GitLab MCP Server

A custom implementation of the GitLab MCP (Model Context Protocol) server for integration with Claude and other MCP-compliant AI assistants.

Overview

This MCP server provides seamless integration with GitLab repositories, allowing AI assistants to:

• Search GitLab repositories
• Fetch file contents
• Create or update files
• Push multiple files in a single commit
• Create issues and merge requests
• Fork repositories
• Create branches

Fixed Implementation

This custom implementation fixes issues with schema validation that were present in the standard GitLab MCP server implementation, specifically for the search_repositories tool.
