Calibre MCP

Ask your AI assistant “which of my books explain consumer-group rebalancing?” and get the exact chapter - across 800+ books or inside one. Curate metadata, dedupe, and safely edit your library, all through natural language. It runs locally over stdio via the published package.

People connecting AI & ML tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

      "command": "npx",
      "args": [
        "-y",
        "calibre-mcp"
      ]
    }
  }
