Connect Claude to Apple Mail and Notes for free

If you want all three apps at no cost and no limit, that is LMCP: free with a permanent licence key, and it covers Mail, Calendar and Notes. If you would rather have open source you can read yourself, iMCP is free under the MIT licence, but it has no Mail and no Notes at all. If a capped allowance is enough, Macuse's free plan is 100 tool calls a day and Pomeroy is free for 50 actions a week, and what separates those two is whether you want your assistant able to send as you.

I built Pomeroy, so this is an interested party's map of what is free. Every fact about another tool was checked on 3 September 2026, each one has a comparison page here listing its sources, and where another tool is the better answer this post says so.

How this list was put together

This list is the five tools this site holds comparison facts about: LMCP, iMCP, Macuse, Pomeroy and apple-mcp. Each has a way to connect an AI assistant to Apple apps without paying, and this post weighs only that free route.

They are ordered by what free costs you. The two with no usage limit come first, LMCP ahead of iMCP because iMCP has no Mail or Notes; then the two whose free tier runs out, larger allowance first; then apple-mcp, whose free route costs you maintenance. Every fact about the other four was checked on 3 September 2026.

Which free ways are there to connect Claude to Mail, Calendar and Notes?

Five, and only two of them are free with no limit on how much you use them. Here is each in turn, ordered as above.

• LMCP is free, with a permanent licence key and no paid tier announced. It covers 188 or more tools, with Mail, Calendar and Notes alongside Outlook, Teams, Slack and WhatsApp, and it sends and replies in six of them. Free here is not silent: the app sends a heartbeat about every five minutes carrying its version, your macOS version, CPU type and a hashed machine identifier. Pick this if you want all three apps for nothing on macOS 13 or later. Not for you if you would rather it could not send mail as you.
• iMCP is free and open source under the MIT licence, with about 1,500 GitHub stars, so free costs you nothing at all: you can read every line and build it yourself. What it costs instead is two of the three apps, because iMCP covers Calendar, Contacts, Location, Maps, Messages, Reminders, Shortcuts and Weather, and has no Mail and no Notes. Pick this if Calendar was the app you wanted and you like open source. Not for you if Mail or Notes is part of the question, or your Mac is older than macOS 15.3.
• Macuse is $49 once, with a free plan of 100 tool calls a day on one connected client, more generous than Pomeroy's weekly allowance. It reaches nine Apple apps, Mail, Calendar and Notes among them, sends mail and messages, drives apps that have no scripting interface through Computer Use, and runs on macOS 13 or later. Pick this if you want a larger free allowance and want your assistant able to act on your Mac rather than only read it. Not for you if one connected client is too few.
• Pomeroy, this one, is free for 50 actions a week with no account and no card, and $19 once removes the weekly limit. The allowance is one count per Mac, shared by every assistant you connect. It covers 9 Apple apps, Mail, Calendar and Notes among them, and it is read-mostly: your assistant can create events, reminders and notes, and cannot send mail or a message. Pick this if you want all three apps from something that cannot send as you, on macOS 15 or later. Not for you if you are on macOS 13 or 14, or if free at any volume is the requirement.
• apple-mcp was free and MIT-licensed, covered seven Apple apps including Mail, Notes and Calendar, and for a year was the answer most people were given, with about 3,100 GitHub stars. It is archived now: frozen on 1 January 2026 and read-only, so there are no fixes for new macOS releases and no answers to issues. Free here costs you maintenance, because when macOS shifts the next fix is yours. Pick this if you already have a working install and want a little longer before you move. Not for you if you are choosing today.

What should you check before picking a free one?

Four things: whether the free tier has a limit, whether it covers the apps you wanted, whether it can send as you, and what it sends off your Mac. Those four separate these five tools completely.

The limit decides whether free is permanent: LMCP and iMCP have none, Macuse gives 100 tool calls a day on one connected client, and Pomeroy 50 actions a week. On apps, four of the five cover all three, and iMCP is the exception. On sending, LMCP, Macuse and apple-mcp can send and reply as you, and Pomeroy has no send action in it.

On what leaves your Mac, iMCP is open source, so its behaviour is there to read, and LMCP's heartbeat is above. Macuse says no cloud and no telemetry of your content, and is closed source, so that is a claim rather than something you can check. Pomeroy sends a licence check, an update check and four pseudonymous usage counts, all listed on its privacy page.

Which free one works with Apple Mail?

LMCP, Macuse's free plan, or Pomeroy's free allowance. iMCP has no Mail service at all, which surprises people, because it is otherwise the obvious free choice. Of the three that do cover Mail, LMCP and Macuse can send and reply; Pomeroy searches and reads and cannot send anything, and the Apple Mail page lists what it can and cannot do there.

Which one runs on macOS 13 or 14?

LMCP or Macuse, both of which run on macOS 13 or later. Pomeroy needs macOS 15 and iMCP needs macOS 15.3, so an older Mac narrows the free field to those two.

Is iMCP still maintained?

Yes, at the time of writing, though it went quiet for about a year. Its last tagged release is 1.4.1 from 7 May 2025, 34 issues are open, one of them asking about the project's future, and it has no in-app updater. Check before you rely on it; the comparison page carries the date its facts were checked.

Which free one works with ChatGPT or claude.ai on the web?

Macuse and LMCP. Macuse reaches both through Remote Access, which needs a Tailscale account, and LMCP through an optional cloud relay that routes requests through its own machines.

Pomeroy offers no equivalent and plans none: it serves the assistants running on that same Mac. If the web version of your assistant is the one you use, Macuse or LMCP is your answer, and I would rather you knew now.

What can Pomeroy not do?

It cannot send. There is no action anywhere in Pomeroy that sends mail, a message, a reply or an invitation, and none that deletes anything in any app. It never creates, edits or deletes a contact, it never edits or deletes an existing note, and the only change it can make to a reminder you already have is ticking it off.

It also cannot read your screen or click around an app for you, and it never asks for Accessibility; an app it has no tools for is reached by a Shortcut you built yourself. And its free allowance is the smallest of the five: 50 actions a week, after which it asks you for $19.

How do you set it up?

Four steps, and none of them is a terminal. Download Pomeroy from the download page and open it, switch on Mail, Calendar and Notes, approve each macOS prompt, then press Set up beside your AI assistant and ask it something:

• "Find the flight confirmation from March and tell me the times."
• "What’s on my calendar today?"
• "Find my note about the boiler pressure."

Every app starts switched off, and you can switch one off again whenever you like.

So which should you pick?

If you want all three apps free with no limit, and you are happy for your assistant to send and reply as you, pick LMCP. It is the only one here free at any volume across Mail, Calendar and Notes, and if your work also lives in Teams, Slack or Outlook it settles the question twice over.

If you want free and open source, and Calendar and Reminders were really what you were after, pick iMCP. If you are on macOS 13 or 14, it is LMCP or Macuse, and Macuse if you want your assistant to act on your Mac rather than read it.

If what you want is an assistant that reads the Apple apps on your Mac, answers from what it finds, and can never send as you, that is what I built Pomeroy for, and 50 actions a week is enough to find out whether it earns the $19. Download it, or read the comparisons first.
