Macuse

Gives Claude or any MCP client native control over Calendar, Mail, Notes, Reminders, Messages, Contacts, and other macOS apps through natural language. You can schedule meetings, draft replies, search notes, create tasks, send iMessages, and run Shortcuts without leaving your chat. Also includes Computer Use for macOS, so you can click elements and drive any app that lacks a direct integration. Everything runs locally through the Macuse macOS app. Each client gets its own OAuth authorization, and sensitive apps require reconfirmation. Useful when you want your AI to actually manipulate Mac apps instead of just suggesting commands to run yourself.
