Native Mac tools for AI assistants. A Swift MCP server for Apple apps, starting with Reminders and Calendar.
Grove is a small macOS menu bar app that lets AI assistants work with Apple Calendar and Reminders.
It is local-first. Your data stays on your Mac. Grove does not need an account, a cloud service, or a database.
- Find calendars and events. - Create, update, and delete events. - Handle all-day events, time zones, repeats, and alarms.
- Find reminder lists and reminders. - Create, update, complete, reopen, and delete reminders. - Handle due dates, priority, repeats, and alarms.
Enable Calendar or Reminders from the Grove menu bar panel. More Apple app integrations will appear as they become available.
When a release is available, download Grove from the Grove download page. It selects the Apple silicon or Intel archive for your Mac. Open the app, then allow Calendar or Reminders access when macOS asks.
Open Grove before you use it. The app keeps its local MCP server ready while it runs. Connect Grove to your AI assistant through its MCP setup. Developer and client setup instructions are in AGENTS.md.
Grove reads and changes Apple data only when an enabled MCP tool is called. It does not copy your Calendar or Reminders data to another store.
