Claude Code

claude mcp add keesan12-martin-loop -- npx -y @martinloop/mcp

{
  "mcpServers": {
    "keesan12-martin-loop": {
      "command": "npx",
      "args": [
        "-y",
        "@martinloop/mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
