# iCloud Mail, Calendar and Contacts in Claude Code > One command adds muse.space to Claude Code. Sign in once, and it can search your iCloud Mail, check your calendar and find contacts, without the password. muse.space wrote this guide, and "we" in it means muse.space. muse.space is an independent project. It is not affiliated with Apple, Meta or any other company whose products it works with. One command in a terminal and a sign-in in your browser. Claude Code gets your iCloud Mail, Calendar and Contacts as tools, and never the password. Start here: [Connect iCloud](https://muse.space/signup). This guide as a web page: https://muse.space/guides/claude-code ## What you can ask Claude Code - “Find Alex’s last email about the API change and write what changed into NOTES.md.” - “Read the spec attached to the design review invite and list its open questions.” - “What meetings do I have before the release on Friday?” - “Put a 30 minute review on my calendar on Thursday at 2.” This one writes, so it waits until you turn writing on for iCloud Calendar. Reading is on from the start. Sending mail, changing events and editing contacts wait until you turn writing on, connector by connector. ## Three steps, about five minutes ### 1. Make an app-specific password Sign in at [account.apple.com](https://account.apple.com/) 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](https://account.apple.com) ### 2. Add it to muse.space [Create an account](https://muse.space/signup) 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. ### 3. Add the server to Claude Code One command, then a sign-in: 3.1. Run this in a terminal: Terminal: ```text claude mcp add --transport http muse-space https://muse.space/mcp ``` 3.2. In Claude Code, type /mcp, choose muse-space and sign in. Your browser opens a muse.space page where you choose what it may use, and allow it. ## 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 Code makes is in your audit log: which tool, when, and how it went. - Revoke the token Claude Code holds, and its calls stop within 5 seconds. One switch pauses every agent at once. - Claude Code never holds the password. Cancel it at Apple and our copy stops working at once. ## Fair things to ask first ### What about other agents in a terminal? Any agent that speaks MCP can use the same address. One that cannot sign in takes an agent token instead, in an `Authorization: Bearer` header: make one under **Tokens** in your dashboard. ### Does every project see it? Only the one you ran the command in, which is Claude Code’s default. Add `--scope user` to the command to use it in every project. Either way, what it may use is decided here. ### 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 Code and not you. The [security page](https://muse.space/security) 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. ## Other guides - [iCloud Mail](https://muse.space/guides/icloud-mail.md): Let Muse, Claude or ChatGPT search, read and answer your iCloud Mail, attachments included, without ever holding the password. Free for up to 3 connectors. - [iCloud Calendar](https://muse.space/guides/icloud-calendar.md): Let Muse, Claude or ChatGPT read your iCloud Calendar and, when you allow it, add and move events. One app-specific password, about five minutes to set up. - [MCP servers](https://muse.space/guides/mcp-servers.md): Muse’s own integrations carry a key. Sign in to Notion, Linear or any remote MCP server through muse.space instead, and Muse gets one agent token for all. - [Claude](https://muse.space/guides/claude.md): Add iCloud Mail, Calendar and Contacts to Claude as a custom connector. Claude signs in, you choose what it may use, and it never sees the password.
