Guide for Claude

iCloud Mail, Calendar and Contacts in Claude

About five minutes. You store an app-specific password here once, then add a custom connector in Claude. Claude signs in, you choose what it may use, and it works on the web, in the desktop app and on your phone.

Free for up to 3 connectors. No card needed.

Once it is connected

What you can ask Claude

“Go through this week’s unread mail and tell me which messages need an answer.”
“What does the contract attached to Dana’s last email say about notice periods?”
“Find a free hour on Thursday afternoon.”
“Which of my contacts work at Northwind?”
“Draft a reply to Dana saying Thursday works.” This one writes, so it waits until you turn writing on for iCloud Mail.

Reading is on from the start. Sending mail, changing events and editing contacts wait until you turn writing on, connector by connector.

Set it up

Three steps, about five minutes

Make an app-specific password
Sign in at account.apple.com (opens in a new tab) and choose Sign-In and Security, then App-Specific Passwords. Name it muse.space and copy the 16 letters Apple shows you.
Open account.apple.com
Add it to muse.space
Create an account and paste the password. Your browser encrypts it before it is sent, and we check it with Apple. The one password opens Mail, Calendar and Contacts.

Add the connector in Claude
Setup ends by walking you through this. At any time after, it is the same few clicks:
1. In Claude, open Connectors, under Customize or Settings.
  Open Claude
2. Choose Add custom connector, and paste this address:
  MCP address
```
https://muse.space/mcp
```
3. Choose Connect. It opens a muse.space page where you choose what it may use, and allow it.
Claude’s free plan takes one custom connector; the paid plans take more.

Control

What stays in your hands

Read tools are on from the start. Every write tool waits for your switch, connector by connector.
Every call Claude makes is in your audit log: which tool, when, and how it went.
Revoke the token Claude holds, and its calls stop within 5 seconds. One switch pauses every agent at once.
Claude never holds the password. Cancel it at Apple and our copy stops working at once.

Questions

Fair things to ask first

Do I need an agent token for Claude?: No. Claude signs in the way you sign in to an app, and asks you what it may use. It is listed with your tokens, where you can change what it may use or revoke it.
Which Claude plans can add it?: Claude’s free plan takes one custom connector; the paid plans take more.
Does it work in Claude on my phone?: Yes. A connector you add on the web works in Claude’s desktop and phone apps too, with nothing to set up again.
Is it safe to give muse.space the password?: It is an app-specific password, not your Apple Account password: it opens mail, calendar and contacts and nothing else, and you can cancel it at Apple whenever you like. Your browser encrypts it for our vault before it is sent, and nothing can read it back, not Claude and not you. The security page says exactly how.
Is this allowed by Apple?: Yes. App-specific passwords are Apple’s supported way for other mail apps to sign in. Ours shows up in your Apple Account like any other, and you can cancel it there at any time without asking us.
What if I stop halfway?: Nothing is lost. Sign in again and setup carries on from the step you were on, and a password you stored stays stored. If you lost the agent token before your agent had it, make a new one: the old one stops working at once.
What does it cost?: Nothing for up to 3 connectors, and a password counts once, so iCloud Mail, Calendar and Contacts are one. Personal, for everything more, is $5 a month or $48 a year. It is not on sale yet, and until it is we give it with codes.
