git clone https://github.com/yoda-digital/mcp-gitlab-server.git
cd mcp-gitlab-server

# Install dependencies
npm install

# Build the project
npm run build

Configuration

Environment Variables

The server requires the following environment variables:

Read-Only Mode

When GITLAB_READ_ONLY_MODE is set to true, the server will only expose read operations. This is useful for client applications that shouldn't have write access to your GitLab resources. In read-only mode, the following tools will be available:

• search_repositories
• get_file_contents
• list_group_projects
• get_project_events
• list_commits
• list_issues
• list_merge_requests
• list_project_wiki_pages
• get_project_wiki_page
• list_group_wiki_pages
• get_group_wiki_page
• list_project_members
• list_group_members

Any attempt to use write operations (create, update, delete) will result in an error when in read-only mode.

MCP Settings Configuration

Add the GitLab MCP server to your MCP settings file:

{
  "mcpServers": {
    "gitlab": {
      "command": "npx",
      "args": ["-y", "@yoda.digital/gitlab-mcp-server"],
      "env": {
        "GITLAB_PERSONAL_ACCESS_TOKEN": "your_token_here",
        "GITLAB_API_URL": "https://gitlab.com/api/v4"
      },
      "alwaysAllow": [],
      "disabled": false
    }
  }
}

For read-only mode, add the GITLAB_READ_ONLY_MODE environment variable:

{
  "mcpServers": {
    "gitlab-readonly": {
      "command": "npx",
      "args": ["-y", "@yoda.digital/gitlab-mcp-server"],
      "env": {
        "GITLAB_PERSONAL_ACCESS_TOKEN": "your_token_here",
        "GITLAB_API_URL": "https://gitlab.com/api/v4",
        "GITLAB_READ_ONLY_MODE": "true"
      },
      "alwaysAllow": [],
      "disabled": false
    }
  }
}

Usage

With stdio transport (default)

# Set your GitLab personal access token
export GITLAB_PERSONAL_ACCESS_TOKEN=your_token_here

# Run the server
npm start

With SSE transport

# Set your GitLab personal access token and enable SSE
export GITLAB_PERSONAL_ACCESS_TOKEN=your_token_here
export GITLAB_READ_ONLY_MODE=false
export USE_SSE=true
export PORT=3000  # Optional, defaults to 3000

# Run the server
npm start

With npx

# Run directly with npx
GITLAB_PERSONAL_ACCESS_TOKEN=your_token_here npx @yoda.digital/gitlab-mcp-server
