Apple Calendar for Claude, Cursor, ChatGPT & agents

Read and write events in the macOS Calendar app — list calendars, today's events, upcoming events, search by free-text, create / update / delete events with attendees, location, all-day flag

curl -fsSL https://syncorelabs.ai/install.sh | sh

What it does

Read and write events in the macOS Calendar app — list calendars, today's events, upcoming events, search by free-text, create / update / delete events with attendees, location, all-day flag. macOS only; uses local AppleScript (JXA), no API key. macOS will prompt for Calendar permission on the first run. Use when the user mentions Apple Calendar, macOS Calendar, iCloud calendar (local), Calendar.app, or wants to manage their local Mac calendar. NOTE on Google Calendar: if the user added their Google account in System Settings → Internet Accounts, Apple Calendar already mirrors Google events locally and this skill returns them — fine for read-only 'what's on my calendar now' lookups. For Google-native operations (create/update/delete on the Google side, attendee invites, RRULE rules) prefer the `google-calendar` skill instead.

The Apple Calendar skill is one of 75+ pre-wired Syncore integrations that any MCP-compatible client — Claude Desktop, Claude Code, Cursor, Windsurf, Codex CLI, and ChatGPT desktop — can call out of the box. You don't configure MCP servers or copy API keys into a JSON file; the Syncore daemon discovers the skill at startup and exposes its tools to whichever AI client is running.

Sample prompts

Once Syncore is installed and Apple Calendar is connected, ask your agent something like:

• “List calendars from Apple Calendar.”
• “List events from Apple Calendar.”
• “List today from Apple Calendar.”

Tools available (11)

• apple-calendar__list_calendars

  List the calendars configured in the macOS Calendar app (Personal, Work, iCloud subscriptions, etc.) with name + writable flag.

• apple-calendar__list_events

  List events between two dates, optionally filtered to one calendar. NOTE: for the specific 'is there a meeting RIGHT NOW' kickoff lookup before note-taker__start_session, prefer `list_current_meeting` — it's a one-call helper that does the now ± 10 min window + 0/1/N candidate disambiguation for you.

• apple-calendar__list_today

  List today's events (local time, midnight to next midnight) across all calendars.

• apple-calendar__list_upcoming

  List events from now through the next N days. Useful for 'what's on my calendar this week'.

• apple-calendar__list_current_meeting

  Find the meeting(s) the user is CURRENTLY IN — events overlapping (now − window_minutes, now + window_minutes) on the LOCAL machine clock. THE preferred kickoff lookup before note-taker__start_session: takes one round-trip, returns 0/1/N candidates plus an `agent_directive` string telling the LLM exactly what to do (as

• apple-calendar__get_event

  Fetch one event by its uid.

• apple-calendar__create_event

  Create a new event in a specific calendar.

• apple-calendar__update_event

  Patch fields on an existing event by uid.

• apple-calendar__delete_event

  Delete an event by uid. Idempotent — succeeds even if the event was already removed.

• apple-calendar__search_events

  Search events by free-text query across summary + location + notes within a date window.

• apple-calendar__list_attendees

  Return the attendees on an event (name + email + response status).

How to connect

Apple Calendar is a no-auth skill — there's nothing to connect. Once Syncore is installed, your agent can call its tools immediately.

1. Run curl -fsSL https://syncorelabs.ai/install.sh | sh on macOS / Linux (or the PowerShell command on Windows).
2. Run syncore login to create your account and a device-bound encryption key.
3. Run syncore update to sync the skill + credentials to every installed AI client.

Pricing

Free at every Syncore tier. Connect your account once at /connect; the OAuth or API-key credential stays encrypted on your machine and syncs to your other devices via the Syncore vault.
