GitLab MCP Server

GitLab MCP Server

interact with a GitLab server.

This is a TypeScript-based MCP server that interacts with a self-hosted GitLab instance. The server provides tools to fetch and manage GitLab data, specifically projects, issues, and issue notes (comments). The available tools are: list_projects, get_issues, get_issue_notes, search, get_issue, get_todos, get_wiki_page, and list_wiki_pages.

Features

This GitLab MCP server provides the following tools:

• list_projects: Lists all projects accessible to the user.
• get_issues: Gets issues for a specific project, with basic filtering.
• get_issue_notes: Gets notes (comments) for a specific issue.
• search: Searches for projects and issues based on a search term.
• get_issue: Retrieves a specific issue from a project using its ID and IID.
• get_todos: Retrieves a list of to-do items with optional filters.
• get_wiki_page: Retrieves a specific wiki page by project ID and slug.
• list_wiki_pages: Retrieves all wiki pages for a given project.

Development

Install dependencies:

npm install

Build the server:

npm run build

For development with auto-rebuild:

npm run watch

Installation

To use with Claude Desktop, add the server config:

{
  "mcpServers": {
    "gitlab-server": {
      "command": "/path/to/gitlab-server/build/index.js",
      "env": {
        "GITLAB_API_TOKEN": "<Gitlab API Token >",
        "GITLAB_HOST": "<GitLab Host URL>"
      }
    }
  }
}

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:

npm run inspector

The Inspector will provide a URL to access debugging tools in your browser.
