[Connectors](https://lumman.co/mcp) / [Multi Calendar](https://lumman.co/mcp/multi-calendar)

iCloud calendars connect to Multi Calendar with an app-specific password, never your Apple Account password.

For the calendars of your Apple Account, added with its email.

## Before you add it

Apple makes an app-specific password only once two-factor authentication is on.

1. Sign in at [account.apple.com](https://account.apple.com).
2. In Sign-In and Security, select App-Specific Passwords.
3. Select Generate an app-specific password and follow the steps. Apple shows it once - leave that page open until Lumman asks for it.

## Add it to Claude

4. [Add to Claude](https://claude.ai/directory/connectors/lumman-multi-calendar) - Opens claude.ai - press Connect there.
5. Sign in, add your iCloud calendar and approve Claude in the window Claude opens - paste the app-specific password when it asks.
6. Ask Claude about your week

## Limits

- Apple sends a meeting's invitations, updates and cancellations itself, from Apple's own address under your name.
- Answer an invitation in an iCloud calendar from its letter or in Apple's Calendar app - Multi Calendar answers none there.
- An event keeps no privacy, out of office, focus time or video link, and shows only as busy or free.
- Changing your Apple Account password ends every app-specific password. Make a new one and reconnect.
