Which Apple apps can Claude connect to on a Mac?
Mail, Calendar, Reminders, Notes, Contacts, Messages, Maps, Shortcuts and Weather, each a separate switch that starts off. What Claude can do in each one, and what none of them allow.
Claude can reach Mail, Calendar, Reminders, Notes, Contacts, Messages, Maps, Shortcuts and Weather on your Mac, through Pomeroy. Pomeroy is a $19 macOS menu-bar app that connects your AI assistant to those apps over MCP. Every app starts switched off, you pick the ones Claude may use, and none of them let Claude send mail or a message.
Which Apple apps can Claude connect to?
Mail, Calendar, Reminders, Notes, Contacts, Messages, Maps, Shortcuts and Weather. Each one is its own switch in Pomeroy, so switching on Calendar does not switch on Mail, and you can switch any of them off again at any time.
Mail. Claude can list your mailboxes with message and unread counts, read messages, and search your mail by sender, subject, or body text. Body search runs through an index built and kept on your Mac. Claude cannot send, reply, delete, move, or archive anything.
Calendar. Claude can read today, one day, or a range of days, across every calendar your Mac shows. It can create an event and change one you name, altering only the fields you mention. It cannot delete an event or answer invitations.
Reminders. Claude can read every list or just one, soonest due first, create a reminder with a due date, and mark one done. It cannot delete a reminder or a list, and it cannot un-tick anything.
Notes. Claude can list your notes by name, read one in full as plain text, and start a new note in a folder you name. An existing note is never edited, moved, or deleted.
Contacts. Claude can search by name, organisation, email address, or part of a phone number, and read back what it finds. Pomeroy never creates, edits, or deletes a contact. Your address book is read, never written.
Messages. Claude can list your recent conversations, search the text of every message, and read one thread. It cannot send a message or a reply, and Pomeroy never asks for Full Disk Access: you hand it the one file Messages keeps your conversations in, and it keeps a read-only bookmark to that file.
Maps. Claude can find places near a named place, with addresses and, where Maps has them, phone numbers and websites. It can route between two named places, driving or walking, with the distance and the expected time. Apple does not route public transport on a Mac, so Pomeroy does not offer it.
Shortcuts. Claude can list the shortcuts you have already made, run one by its exact name, and pass a line of text into it as input. It cannot create, edit, or delete a shortcut, and a near miss on a name runs nothing.
Weather. Claude can read current conditions and a daily forecast for any place you name, from Apple's own WeatherKit, the same source the Weather app uses.
What can you ask Claude once the apps are on?
You ask in plain English, the way you would ask a person. Claude works out which app to look in and reads only what it needs to answer.
Some asks that work today:
- "What's on my calendar today?"
- "Find the flight confirmation from March and tell me the times."
- "Find the message with the door code."
- "Remind me to renew my passport next Friday."
- "Run my Wind Down shortcut."
Questions that cross two apps work too, because Claude can use both in one answer. "Who do I know at Acme, and what did we last email about?" reaches Contacts and Mail. "What's on tomorrow, and will it rain?" reaches Calendar and Weather.
What can Claude not do in any of these apps?
Claude cannot send mail, and it cannot send a message or a reply. It cannot delete anything, in any of the apps, and it never creates, edits, or deletes a contact.
There is no action in Pomeroy for any of those, so no prompt can talk Claude into one. The capability does not exist to be found.
The writing Claude can do is small and named: create an event, change one you asked it to change, create a reminder, mark a reminder done, create a note, and run a Shortcut you built. Nothing else.
Two more limits worth knowing. The maps and weather actions take place names, never your location. And Pomeroy never reads your screen and never asks for Accessibility or Screen Recording, so an app it has no actions for is reached by a Shortcut you made yourself, with you deciding the steps.
How do I connect Claude to these apps?
Setup is four steps and takes a couple of minutes. Download Pomeroy, switch on the apps you want and approve the macOS prompt for each, press Set up beside Claude in the list of assistants Pomeroy finds, then ask Claude something.
There is no Terminal command and no configuration file to edit. Pomeroy needs macOS 15 or later and an AI assistant on the same Mac.
Do I have to switch on every app?
No. Every app starts off, and you switch on only the ones you want. If you want Claude to see your calendar and nothing else, switch on Calendar and leave the rest alone.
You can change your mind at any time. Switch an app off and Claude stops reading it from that moment.
Where does my data go?
Your app data stays on your Mac. Pomeroy reads the app you asked about and hands the result to Claude, which sends it on as part of your conversation, the same as text you paste in yourself. Nothing from your apps is sent to Pomeroy, because there is nowhere of Pomeroy's for it to go.
What Pomeroy sends on its own is a licence check when you enter a key, a signed update check you can switch off, and four pseudonymous usage counts that carry no content from your apps. The full list is on the privacy page.
What does it cost?
Pomeroy is free for 50 actions a week, with no account and no card. $19 once removes the weekly limit, there is no subscription, and there is a 14-day refund for any reason. See pricing for the detail.
The allowance is per Mac and shared across every assistant you connect, so connecting a second one costs you nothing.
Is Pomeroy made by Anthropic?
No. Pomeroy is an independent app made by Joe Saunderson, and Anthropic does not make, sell, or support it. Claude is one of the assistants Pomeroy can set itself up in.
