Do I need my main Apple ID password to use this server?

No. You must generate an app-specific password from your Apple ID account settings and provide that instead of your main password. This keeps your primary credentials secure.

What calendar operations can I perform with this MCP server?

The server connects to iCloud Calendar via CalDAV protocol, allowing you to read and manage calendar events. Specific operations depend on CalDAV standard capabilities—consult the server documentation for the full list of supported tools.

How do I set up the required environment variables?

Set ICLOUD_USERNAME to your Apple ID email and ICLOUD_PASSWORD to your app-specific password before running the server. Both are required for authentication.

Can I access multiple iCloud calendars or just the primary one?

The server connects via CalDAV, which typically supports multiple calendars. Check the server documentation or README for details on calendar selection and multi-calendar support.

Is this server maintained and what version should I use?

Install via `npx @icloud-calendar-mcp/server@3.0.0`. Verify the package registry for the latest version and any breaking changes between releases.
