iMCP is a macOS app that provides an MCP server to enable AI assistants like Claude Desktop to securely access system services including Calendar, Contacts, Location, Maps, Messages, Reminders, and Weather.
Users activate each service individually, granting permission for access according to Apple's security model, and iMCP does not collect or store user data. The app includes tools for debugging and is implemented as both a GUI and a CLI, with data exchanged using JSON-LD and custom Swift packages for database decoding.
