Frequently asked questions

How does this server differ from Google Calendar or iCloud integrations?

It operates entirely locally using macOS Apple Events, with no OAuth tokens, no cloud relays, and no requirement to expose private iCloud data.

What permissions does the server need?

The first run requires manually granting UI permission via macOS Transparency, Consent, and Control (TCC). Nothing can access your calendar silently.

Can my calendar data be sent to an external server?

No, all data is read and written locally on your Mac. Your calendar data never leaves your machine.

Are there any runtime dependencies?

None beyond macOS and an MCP client. The server is a zero-dependency solution.

Does it work with MCP clients other than Claude?

Yes, it is designed as a bridge for any MCP client, though the quick setup example shows Claude Desktop configuration.
