What is the Apple Calendar MCP Server?

Apple Calendar is an MCP integration. Search, read and act on Apple Calendar — ranges, free-time lookup, writes off by default.

Packages and local setup

The published npm package is @mgcrea/mcp-apple-calendar, version 1.27.0. Its declared MCP transport is stdio.

The package declares APPLE_CALENDAR_ALLOW_WRITES: Register the mutating tools. Off by default, and the gate decides whether the write tools exist at all rather than merely refusing — an agent with writes off cannot see them.; APPLE_CALENDAR_CALENDARS: Restrict every read and write to these calendars, by name.; APPLE_CALENDAR_ACCOUNTS: Restrict every read and write to these Calendar accounts, by name or id. Bounds reading, not just writing..

Before connecting

Check the maintainer’s instructions for account access, authentication and the supported client configuration. Once connected, inspect the tools your client receives and try a small task that matches the server’s stated purpose. The registry description does not include a verified, complete tool list.
