gitlab-mcp-server

Model Context Protocol (MCP) server for GitLab integration, built on FastMCP.

This server is implemented in Python, with fastmcp.

1. Build the Docker image:

docker build -t gitlab-mcp-server .

In MCP Settings -> Add MCP server, add this config:

{
  "mcpServers": {
    "gitlab": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "-e",
        "GITLAB_TOKEN",
        "-e",
        "GITLAB_URL",
        "gitlab-mcp-server:latest"
      ],
      "env": {
        "GITLAB_TOKEN": "token",
        "GITLAB_URL": "https://gitlab.com/"
      }
    }
  }
}

Note: Don't forget to replace GITLAB_TOKEN and GITLAB_URL values with your actual GitLab credentials and instance URL.

1. Log in to your GitLab account
2. Go to Settings -> Access Tokens
3. Create a new token:
   • Scopes: select the necessary permissions:
     • api - for API access
     • read_repository - for reading repositories
     • write_repository - for writing to repositories
4. Click "Create personal access token"
5. Copy the generated token (it will be shown only once!)

Here are some suggestions to improve and clarify your review.mdc rules for code review:

review.mdc (Improved Version)

Purpose:
Guidelines for conducting code reviews in the current branch, focusing on diffs with the origin/master branch, and integrating with the MCP GitLab server.

• Review only the changes in the current branch compared to the origin/master branch.
• Locate the corresponding Merge Request (MR) for this branch in GitLab using MCP tools.

• Summary of Changes:

  • Provide a concise summary divided into two sections:
    • Business Changes: Describe the impact on business logic, user experience, or requirements.
    • Code Changes: Summarize technical modifications, refactoring, or architectural shifts.

• Logical Breakdown:

  • Divide the changes into logical blocks (e.g., features, bug fixes, refactoring).
  • List these blocks clearly.

• Detailed Review:

  • For each block, provide:
    • A brief description.
    • Suggestions for improvement (code quality, readability, maintainability, performance, etc.).
    • Identification of potential bugs or issues.
    • Illustrate type of suggestion with emoji.
    • Link to line in code.
  • If the terms of reference (requirements/spec) are not provided, request them to ensure accurate review.

• Propose to post line comments with suggestions directly in the Merge Request using the MCP GitLab server.
• All line comments in Merge Request must:
  • Begin with "[AI]".
  • Be specific, actionable, and reference the relevant code line(s).
  • Do not write a lot of text. Smaller is better.

• Prioritize clarity, conciseness, and constructiveness in all feedback.
• Focus on both business logic and code quality.
• Ensure all suggestions are justified and, where possible, reference best practices or project standards.
• If you identify a bug, explain the reasoning and potential impact.

Feel free to:

• Add new GitLab integration tools and features
• Improve existing functionality
• Fix bugs
• Enhance documentation
• Suggest improvements
