Score: 7.0/10 (Innovation: 7, Technical: 8, Documentation: 6, Utility: 6)

Cupertino provides MCP servers that expose Apple apps on macOS (Mail, Notes, Calendar, Contacts, etc.) to AI agents through a single Full Disk Access grant held by a signed menu-bar app. It implements a novel hybrid query strategy—using Envelope Index for Mail and Apple Events for Notes—to avoid expensive full scans, with a write toggle and live tool log for safety and observability.

Target audience: macOS developers and AI agent users
