A short video about what MCP for iCloud can do and how to set it up.
What you can do
Ask in your own words, and your AI app does the work in your iCloud.
Find, read and summarize messages and attachments. Write drafts, reply, forward and send from your iCloud or custom-domain addresses, and keep your mailboxes tidy.
Calendar
See what is coming up across your calendars. Create, change and move events, and invite people.
Your own email domains
Use the custom domains you set up with iCloud+. Your AI app can send from any of your addresses, and replies go out from the address the message was sent to.
Works with any AI app
Built on the Model Context Protocol (MCP), the open standard that AI apps use to connect to tools and data. Any app that supports it can connect, and one account works with all of them.
You stay in control
See every connected app and revoke its access with one click. Follow each request in the live activity log, or turn on read-only mode.
Try asking
A few ideas to get you started. Your AI app picks the right tools by itself.
What is on my calendar tomorrow?
Find the latest invoice from Acme and summarize it.
Reply to Anna that I can make it on Friday.
Move the dentist appointment to next Tuesday at 9.
Summarize the unread emails from this week.
Find a free hour next week and invite Tom to a call.
How it works
Setup takes a few minutes, and you only do it once.
Request access
Send a short request. Once the administrator approves it, you can sign in.
Add your iCloud details
Enter your iCloud email address and an app-specific password. You create one at account.apple.com, under Sign-In and Security.
Connect your AI app
Add this server to your AI app, then sign in and approve access when the app asks. Your account page has one-click links and step-by-step help for the common apps.
The address of this server for your AI app:
https://icloud.mcp.visin.ch/mcpPrivacy and security
Built so that your Apple Account stays yours and you can see what happens.
Only an app-specific password
You never give this server your Apple Account password. You can revoke the app-specific password at account.apple.com at any time.
Stored encrypted
Your app-specific password is encrypted with AES‑256‑GCM and is only used to talk to iCloud for you.
Your mail is not kept here
Your mail and events pass between iCloud and your AI app and are not stored on this server. The activity log keeps only which app used which tool, when, how long it took and whether it worked.
Read-only mode
Turn it on and AI apps can read, but never send, change or delete anything.
You approve every app
Each AI app must be approved by you before it can connect, and you can revoke its access at any time.
The details are in the privacy policy and the terms of use.
Questions and answers
Which AI apps work?
Any app that can connect to a remote MCP server with sign-in (OAuth), for example Claude, ChatGPT, Gemini, Codex, Cursor, VS Code, Le Chat and Perplexity. Some apps offer custom connectors only on certain plans, in certain countries or behind a developer setting. Your account page has step-by-step help for each app.
Do I need to give my Apple Account password?
No. You create an app-specific password for this service at account.apple.com. It cannot be used to sign in to your Apple Account, and you can revoke it at any time.
Does it work with my own domain?
Yes. If you use a custom email domain with iCloud+, your AI app can read the mail sent to those addresses and send from them. Add the addresses on your account page.
Can it read my iCloud Drive or Photos?
No. Apple offers no access to iCloud Drive or Photos with an app-specific password, so this service cannot reach them. It works with Mail and Calendar.
Can it reach Notes or Reminders?
No. Apple keeps Notes and Reminders in a store that third-party apps can reach only through the Notes and Reminders apps on an iPhone, iPad or Mac, not with an app-specific password. So this service covers Mail and Calendar.
Who runs this server?
MCP for iCloud is an independent open-source project, not made by, affiliated with, or endorsed by Apple. This server is run by its administrator, who decides who can get an account. Your data passes through the server, so use one run by someone you trust, or run your own.
