Best MCP server for Apple Notes and Calendar

It comes down to two questions: do you need both apps, and do you want your assistant able to send mail or a message too? iMCP is free but has no Notes service at all, so it drops out the moment Notes is part of the question. Cover Notes and Calendar together and the choice is LMCP (free), Pomeroy ($19) or Macuse ($49), and which of those three depends on whether you want it to send.

I should say plainly that I built Pomeroy, so this is an interested party's map of the landscape. Every fact about another tool was checked against its own site or repository on 3 September 2026, each one has a comparison page here with its sources listed, and where another tool is the better answer this post says so.

How this list was put together

This list covers the five tools this site has a comparison page for: iMCP, Macuse, LMCP, Pomeroy and apple-mcp. It is ordered by whether each one covers both Notes and Calendar, then by price among the ones that do: LMCP is free, Pomeroy is $19, and Macuse is $49. iMCP comes after those three because it does not cover Notes at all, and apple-mcp comes last because, although it once covered both apps, its repository is archived and no longer receives fixes. Every fact about the other four tools was checked against their own sites or repositories on 3 September 2026.

Which MCP servers cover Apple Notes and Calendar?

Four of the five do. Macuse, LMCP, Pomeroy and apple-mcp all connect an assistant to both apps; iMCP covers Calendar but has no Notes service. Here is each in a paragraph, with the fact that earns it its place on this list.

• LMCP is free, with a permanent licence key and no paid tier announced. It covers 188+ tools: the Apple apps Pomeroy covers except Maps and Shortcuts, so Notes and Calendar sit alongside Mail, Reminders and Messages, plus Outlook, Teams, Slack and more. It sends and replies in Mail, Outlook, Messages, Teams, Slack and WhatsApp, and runs on macOS 13 or later. Pick this if you want Notes and Calendar for nothing, plus your work apps, on an older Mac. Not for you if you want to know exactly what leaves your Mac: its app sends a heartbeat about every five minutes carrying your macOS version, CPU type and a hashed machine identifier, and records install events with your approximate location.
• Pomeroy, this one, is $19 once and read-mostly across 9 Apple apps, Notes and Calendar among them. In Calendar it reads your schedule, creates an event, and changes one you name; in Notes it finds a note, reads it in full, and starts a new one, and never edits or deletes an existing one. It needs macOS 15 or later and sets itself up in one click with no Terminal. Pick this if you want your assistant in both apps with a guarantee it can never send anything from your Mac. Not for you if you are on an older Mac, or you want to edit an existing note rather than only read and create one.
• Macuse is $49 once, with a free plan of 100 tool calls a day on one connected client. It reads and writes across 9 Apple apps including Calendar and Notes, sends mail and messages, and can drive apps that have no scripting interface through Computer Use. It runs on macOS 13 or later. Pick this if you want your assistant to edit an existing note or event, not just create one, and you are happy paying more for it. Not for you if you want the cheapest option or would rather your assistant could not send anything.
• iMCP is free and open source under the MIT licence, with about 1,500 GitHub stars. It covers Calendar, Contacts, Location, Maps, Messages, Reminders, Shortcuts and Weather, and creates calendar events and reminders, but it has no Mail or Notes service. It needs macOS 15.3 or later. Pick this if Calendar is all you need and you want free, open-source software you can read yourself. Not for you if Notes is part of the question: iMCP simply does not cover it.
• apple-mcp covered both apps, plus Messages, Contacts, Mail, Reminders and Maps, free under the MIT licence, and for a year it was the default answer. Its repository was archived on 1 January 2026 and is read-only: no fixes for a new macOS release, no security patches, no answers to issues. Pick this if you already have it installed and it is still working for you today. Not for you if you are starting fresh: nothing here will be fixed when it next breaks.

What should you check before picking one?

• Does it cover both Notes and Calendar? LMCP, Pomeroy, Macuse and apple-mcp do. iMCP covers Calendar only.
• Can it send mail or a message, not just read and add? Macuse and LMCP can. Pomeroy and iMCP have no send tool at all, in either app.
• Which macOS are you on? Macuse and LMCP run on macOS 13 or later. Pomeroy needs macOS 15 and iMCP needs macOS 15.3, so an older Mac narrows the field.
• Is it still maintained? apple-mcp is not: its repository was archived on 1 January 2026. The other four are actively developed, though iMCP's own commits were quiet for about a year before resuming in September 2026, so it is worth a look at its repository before you rely on it.

Does iMCP work with Apple Notes?

No. iMCP covers Calendar, Contacts, Location, Maps, Messages, Reminders, Shortcuts and Weather, and it has no Mail or Notes service. If Notes is part of what you are asking for, look at LMCP, Pomeroy, Macuse or apple-mcp instead, each of which covers it.

Which one runs on macOS 13 or 14?

Macuse or LMCP. Both run on macOS 13 or later. Pomeroy needs macOS 15 and iMCP needs macOS 15.3, so an older Mac narrows the field to those two, with no way around it in either of the others.

What happened to apple-mcp, and can I still use it?

Its GitHub repository was archived by its owner on 1 January 2026 and is read-only. For a while you can keep using an install you already have: nothing switches it off by itself. But Mail, Messages and Notes scripting shifts with macOS, and nobody will fix the next thing that breaks, so plan the move before a macOS update forces it.

What can't Pomeroy do?

Pomeroy cannot send mail or a message, and it never deletes an event, a note, a contact or a reminder. In Notes, starting a new note is the only write action: an existing note is never edited or deleted. In Calendar, your assistant can create an event and change one you name, but it never deletes one and never sends or answers an invitation. It also cannot read your screen or click around an app for you: there is no Computer Use and it never asks for Accessibility. And it is Mac only, on macOS 15 or later, for assistants running on that same Mac. If any of those is the thing you needed, one of the others above is your answer, and I would rather you knew now.

How do I set it up?

Setting Pomeroy up is four steps: download it, open it, switch on Notes and Calendar, or any other app you want, and press Set up beside your AI assistant. macOS asks you to approve Notes and Calendar access along the way, and nothing is requested until you flip each toggle. Download Pomeroy.

Which should you pick?

If you want it free and are willing to accept what LMCP sends off your Mac in exchange, LMCP covers Notes, Calendar and more at no cost, including on an older Mac.

If you want your assistant to edit an existing note or event outright, not just create one, and you do not mind paying more for it, Macuse does that and can send mail and messages besides.

If Calendar is genuinely all you need and Notes was never really the point, iMCP is free, open source, and there is no reason to pay for an app that only needs one of these two.

If what you want is an assistant that can read your Notes and Calendar, add to them, and never send or delete anything, that is what I built Pomeroy for. Download it or read the comparisons first; both are more useful than a list of features.
