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.
