How to connect codex to apple mail

Pomeroy lists the assistants it finds on this Mac, so install Codex first if it is not there yet.

  1. 1

    Download Pomeroy and switch on Apple Mail.

    Open the download, drag Pomeroy into Applications, and open it. Pomeroy opens a setup window listing every app it can connect. macOS asks whether Pomeroy may control Mail, which is how one Mac app reads another's mail. The prompt names Pomeroy, and nothing is requested until you flip the toggle.

  2. 2

    Press Set up beside Codex.

    Pomeroy runs Codex's own codex mcp add command, which writes to Codex's configuration file. The CLI, the IDE extension and the ChatGPT desktop app all read that one file, so you set up once. If the codex command is not where Pomeroy can find it, Pomeroy adds the entry to the file itself.

  3. 3

    Check Codex.

    Run codex mcp list in the Terminal and pomeroy is listed. In the ChatGPT app, Settings › MCP servers shows it. Quit Codex and open it again.

  4. 4

    Ask Codex something.

    Try “Find the flight confirmation from March and tell me the times.” and a real answer comes back.

The configuration, in full

Set up writes it for you. The documentation has the exact text, where it goes, and how to check it worked.

Can Codex read my Apple Mail?

Yes. Once you switch Mail on in Pomeroy, Codex can list your mailboxes, read messages, and search your mail. Searches cover subjects and senders, and message bodies through an index built and kept on your Mac.

Can Codex send email for me?

No. Pomeroy has no way to send, reply, or forward, so Codex cannot be talked into it. If you want a reply written, Codex can draft the words and you send them yourself.

Is it safe to connect Codex to Apple Mail?

Pomeroy reads your mail on your Mac and sends nothing to a Pomeroy server. What Codex reads becomes part of your conversation, the same as text you paste in. Mail starts switched off, and you can switch it off again at any time. Pomeroy is an independent app, not made by Anthropic.

Codex does not show Pomeroy's tools.

Quit Codex completely and open it again; it reads its configuration when it starts. Then press Set up again in Pomeroy, under Settings › Assistants: every way Pomeroy sets an assistant up is safe to run twice. Pomeroy's menu bar shows whether Codex is connected right now.
