Email inboxes
for AI agents.
Give your agent its own address. It signs up, waits for the verification email and reads the code — on its own.
Paste it into Claude Code or Codex. Or set it up yourself

Waits for the email
wait_for_message returns the moment the email lands, with the whole body. No polling loop.
Signs in once
GitHub sign-in in the browser. Claude Code and Codex keep the session; there are no keys to paste.
Free to start
20 new inboxes a day per account. Each one lives for 7 days. Receive-only.
Set it up yourself
The same thing the sentence above asks your agent to do.
Add the server, then run /mcp in Claude Code to sign in with GitHub.
