Macuse

Macuse is an on-device Model Context Protocol (MCP) server for macOS that empowers AI models to directly read from and control native Mac apps such as Calendar, Mail, Notes, Reminders, Messages, and others. It works seamlessly with a variety of MCP-compatible AI clients, including Claude Desktop, Cursor, Codex, Raycast, and more. Macuse enables both deep native integrations and general computer control, letting AI automate tasks, manage app data, and interact naturally with your Mac ecosystem, all with strong privacy controls and per-app permissions.
