Install GitLab Documentation MCP Server for Claude Desktop

Claude Desktop reads mcpServers from claude_desktop_config.json. Restart the app after saving.

Open ~/Library/Application Support/Claude/claude_desktop_config.json on macOS, %APPDATA%\Claude\claude_desktop_config.json on Windows, or ~/.config/Claude/claude_desktop_config.json on Linux.
Paste the JSON config below.
Replace placeholder secrets, then restart the client if it does not reload on its own.

~/Library/Application Support/Claude/claude_desktop_config.json
