Apple Calendar (iCloud)

Connect your iCloud calendar over CalDAV. Your AI agent lists your calendars, reads events in a date range, finds free slots, and creates new events, all from plain language. It uses an Apple ID and an app-specific password, not your main password, and is revocable any time.

Credentials

All data is protected on the server with AES-256-GCM encryption.

The app password is not your main Apple password. Generate it here: appleid.apple.com → Sign-In and Security → App-Specific Passwords → Generate (two-factor authentication required). You can revoke the password there at any time.

Decide whether your assistant can only read, or also make changes through this connector.

What is it for?

The Apple Calendar connector talks to the iCloud CalDAV server (caldav.icloud.com) using your Apple ID and an app-specific password. We do not store your main Apple password, only a separate password generated just for this purpose, which you can revoke any time at appleid.apple.com. The connector discovers your calendars (principal and calendar-home discovery), reads events for a given range, computes free slots within your working hours, and creates new events. Writing events is gated by default and only activates when you enable advanced access on the connector.
