get_mac_bundle_id
Extract the bundle identifier from a macOS .app bundle by providing the full path to the application. Use this tool to retrieve the unique identifier required for macOS app management and automation tasks.
Instructions
Extracts the bundle identifier from a macOS app bundle (.app). IMPORTANT: You MUST provide the appPath parameter. Example: get_mac_bundle_id({ appPath: '/path/to/your/app.app' }) Note: In some environments, this tool may be prefixed as mcp0_get_macos_bundle_id.
