Resumen de MCP Servers
Apple Calendar MCP
Let Claude read, search and plan your Apple Calendar: fast, local, and nothing deleted or sent to other people without your OK.
Apple Calendar MCP is an MCP server for the Calendar app on your Mac, plus a small menu bar app. Claude (Claude Code, the Claude app, or any MCP client) can see your day, search years of events, find free time across all your calendars, plan focus blocks, prepare meetings, and add or move events, and it can only delete an event, or change one other people are invited to, after you click OK.
The companion of Apple Mail MCP, built the same way.
Any calendar account, ready for AI
Apple Calendar MCP works with every calendar you can add to Calendar: iCloud, Google, Microsoft 365 and Exchange, Yahoo, Fastmail, any CalDAV server, subscribed calendars (holidays, sports, team schedules), birthdays, and calendars on your Mac only.
Your provider needs no API, no developer account and no MCP support of its own. Add the account in Calendar › Settings › Accounts as you normally would; as soon as Calendar syncs it, every tool works with it, side by side with the others. Your passwords stay with macOS: this app never sees them and never connects to your provider.
Why another Calendar server?
Most Calendar servers drive Calendar with AppleScript. Calendar then walks its events one by one, so a search over a busy year takes seconds or times out, repeating events come back wrong, and Calendar is busy meanwhile.
Apple Calendar MCP uses EventKit, the framework Calendar itself is built on. Reads are database queries that return in milliseconds, repeating events expand exactly as Calendar shows them, and Calendar never has to run.
Fast: a day, a week or a year of events in milliseconds, from every account at once.
Free time that knows your week: working hours, buffers between meetings, all-day and declined events handled the way Calendar shows them.
Safe by default: deleting asks first, changes to events other people are invited to ask first, every change can be undone, and each calendar is yours to set: Claude may change it, only read it, or never see it.
Many changes, one OK: a week of focus blocks or a rescheduled afternoon is one call, one approval and one undo.
Reminders too: with Reminders access, Claude lists, adds and ticks off reminders, and the agenda shows what is due.
One permission (two with Reminders): given once to the menu bar app. No Full Disk Access, no Automation.
No passwords, no cloud: everything stays on your Mac.
Install
Homebrew:
brew install --cask mp-consulting/tap/apple-calendar-mcpOr download the app or the Claude extension from the latest release:
| File | For |
|---|---|
AppleCalendarMCP-x.y.z.dmg | The menu bar app with the server inside: Calendar access, approvals, activity, skills, one-click setup. Required. |
AppleCalendarMCP-x.y.z.mcpb | The Claude app only: double-click to install the server as a Claude extension. It still needs the app above for Calendar access. |
Both are notarized, signed with Developer ID, and run on Apple silicon and Intel Macs (macOS 14+). The server is also
listed in the MCP registry as io.github.mp-consulting/apple-calendar-mcp.
Then:
Open Apple Calendar MCP: a calendar appears in the menu bar.
Click Allow Calendar Access and choose Allow Full Access in the macOS prompt.
Open the Claude tab and click Connect next to Claude Code and/or the Claude app.
Permissions
macOS gives calendar access to the app that starts a process. Claude, a terminal or an editor starts the server, and none of them can be given Calendar access on its behalf. So the menu bar app holds the Calendars permission, and servers reach your calendars through it, over a socket in your owner-only support folder. Each side checks the other's code signature: the app answers only this project's server, and the server talks only to this project's app. If the app is not running, the server opens it in the background.
| Permission | Why | Where |
|---|---|---|
| Calendars › Full Access for Apple Calendar MCP | Read and change events | Asked once by the app; System Settings › Privacy & Security › Calendars |
| Reminders › Full Access (optional) | Read, add and complete reminders | Asked when you turn Reminders on in the app's Settings tab; System Settings › Privacy & Security › Reminders |
What Claude can do
| Tool | What it does |
|---|---|
agenda | Today (or the next days) in one call: what's now and next, conflicts, free time left, open invitations, reminders due |
list_events | Events in a period, from all calendars or some, repeating ones expanded |
search_events | Text, person, place, calendar, dates, video calls, status; or counts per calendar, month, weekday or person with group_by |
get_event | One event in full: notes, attendees and their answers, alarms, repeat rule, video link |
find_free_time | Slots of a given length within your working hours, with buffers, across every calendar that counts; within someone else's working hours in their time zone too; as text to paste in a message |
find_conflicts | Overlapping events that both take the time |
find_duplicates | Events entered twice, which copy to keep, and which copies can safely go |
pending_invitations | Invitations you haven't answered |
respond_to_invitation | Accept, decline or answer "maybe" to an invitation; Calendar sends the answer to the organizer |
calendar_statistics | Where time went: per calendar, weekday, hour and person, meeting load, back-to-back meetings |
list_calendars | Calendars with their account, colour and whether they can be changed |
create_event, update_event, delete_event | Add, change, move or delete events, one occurrence or the whole series, with alarms and repeat rules |
create_events, update_events | Many events in one call, checked before any change, one approval and one undo for all of them |
list_reminders, create_reminder, update_reminder, delete_reminders | Reminders: what's open or overdue, add one with a due day or time, tick it off, move it to another list |
undo_change | Lists recent changes and puts one back |
import_ics, export_events | Add events from an .ics file (an invitation saved from Mail), or write events to .ics, CSV or JSON: free/busy only, or as an invitation to attach to an email |
open_in_calendar | Show an event or a day in Calendar |
Event ids are EventKit's own; one occurrence of a repeating event is #.
EventKit cannot invite people from Calendar. Invite them in Calendar, or by email: export_events with invite
writes a standard invitation they can accept or decline, and the calendar-invite-by-mail skill attaches it to a
draft in Mail (with Apple Mail MCP). Invitations to you can be answered with
respond_to_invitation, which uses the same (undocumented) EventKit call as Calendar; the account sends the answer
to the organizer, and the app asks you first.
You stay in control
When Claude wants to delete events, or change an event other people are invited to, a small window pops up with what would change; nothing happens without a click on OK.
Delete policy (Settings): Ask me first (the default), Delete right away, or Never delete.
Shared events: changes to events with other attendees ask first by default, because their calendar server may tell them.
