Model Context Protocol server for retrieving and managing Chrome browser tabs information. This allows Claude Desktop (or any MCP client) to fetch information about and control currently open Chrome tabs.

    }
  }
}

1. Enable Accessibility for Chrome:
   • Open System Settings
   • Go to Privacy & Security > Accessibility
