Can it reach my Notes, Reminders or iCloud Drive?

No. Apple has no supported way for other apps to reach Notes, Reminders or iCloud Drive, so they are not offered. Only Mail, Calendar and Contacts are.

What does it never do without me?

Sending, replying to and forwarding mail ask first, and so does deleting an event or a contact, because that cannot be taken back. It does not change an event or contact in place and does not invite guests, which would send mail from your account.

Why did it stop working?

Changing your Apple Account password revokes every app-specific password. Make a new one and sign in again in the console.

Does Codex see the password or key for iCloud?

No. You sign in to iCloud through Flowplane, which keeps that sign-in sealed. Codex only gets a Flowplane sign-in for you, which you can revoke in the console.

Can Codex change things in iCloud without asking?

Not by default: every change in iCloud waits for your approval in the browser. Your workspace’s rules decide, per tool.

Connect Codex to iCloud

Codex reaches iCloud through one Flowplane address. You add iCloud once in Flowplane, add that address to Codex, and sign in. Read, sort and send your iCloud Mail, check and plan your calendar and find contacts with your AI assistant. Sending and deleting ask first.

Add iCloud in Flowplane
At account.apple.com, open Sign-In and Security, App-Specific Passwords and generate one. In the Flowplane console, add iCloud and paste your iCloud address with that password, not your Apple Account password.
Apple lets only apps it has approved sign in with the Apple Account itself to Mail, Calendar and Contacts, so it works the way every mail and calendar app does: your iCloud address and an app-specific password you make at account.apple.com (two-factor authentication must be on). It is your own account, so each person connects their own. Flowplane keeps the password sealed; the assistant never sees it.

Add Flowplane to Codex
Your address is shown in the Flowplane console; it looks like
https://mcp.flowplane.eu/<your-label>
1. Add the server with the first command below.
2. Sign in with the second: your browser opens Flowplane; sign in and allow Codex.
3. In the IDE extension: MCP servers › Add server, choose Streamable HTTP, paste https://mcp.flowplane.eu/<your-label>, then Authenticate.
```
codex mcp add flowplane --url https://mcp.flowplane.eu/<your-label>
codex mcp login flowplane
```

Ask Codex
- “Show the unread mails in my iCloud inbox from this week.”
- “What is on my calendar between Monday and Friday?”
- “Find Marie’s phone number in my contacts.”
- “Put the dentist in my calendar on 3 December at 14:00.”
- “Move every newsletter from yesterday to my Reading folder.”

What it can do

What Codex can do in iCloud

iCloud is one connector for the Mail, Calendar and Contacts of your Apple Account, and you choose which of the three it reaches. Through Flowplane an AI assistant can search and read your mail and download an attachment, list your events and search your contacts. It can also send, reply, forward, sort and delete mail, add or remove an event and add or remove a contact, and those changes wait for your approval.
