iCloud Calendar MCP
@kembec/ical-mcp · Model Context Protocol Server
Install
npm install -g @kembec/ical-mcp Generate an app-specific password at appleid.apple.com → Sign-In & Security. Your regular Apple ID password will not work.
A lightweight Model Context Protocol server for iCloud Calendar written in Rust. Communicates directly with Apple's CalDAV servers — no intermediary APIs, no cloud relay. Authenticate once with an app-specific password from appleid.apple.com, then give Claude, Cursor, or any MCP client full read/write access to your iCloud calendars through five focused tools. Ships as a single static binary: no JVM, no Python runtime, no native build step.
What you can do
Read and search events across iCloud calendars from Claude
Create timed or all-day events with description and location
Update or delete events by UID without opening Calendar.app
Lightweight alternative for Apple ecosystem users
Requirements
- An active iCloud account
- App-specific password generated at appleid.apple.com → Sign-In & Security
