Macuse

Meet Macuse

Macuse connects MCP-compatible AI clients to applications on a Mac. It provides native tools for Calendar, Mail, Notes, Reminders, Contacts, and Messages, so an authorized assistant can work with everyday information through conversation. Its Computer Use tools extend this to apps without dedicated integrations and can operate in the background.

The app detects supported clients such as Claude Desktop, Cursor, and Raycast and helps configure their connections. Users choose which macOS permissions to grant and can revoke client access. Tools execute locally, while requested content is returned to the authorized AI client and may be processed by that client's model provider. Free and paid plans differ in usage limits.
