A mailbox for AI agents on Cloudflare. Receive, search, read and send email over MCP or REST, behind one token.
- 📥 Catch-all inbox: every address on your domain lands here, with attachments. Optionally accept only the addresses you list, and cap mail per day. - 📤 Send, reply and forward from your domain, with names, cc, bcc, reply-to, attachments and threads. - ⏳ Wait for mail: blocks until a matching email or a reply in a thread arrives, and pulls out its verification code and link. - 🔎 Search by sender, recipient, thread, date, unread, category or text, HTML-only mail included. - 🤖 MCP server at /mcp: eight tools, stateless, works with Claude Code and any MCP client. - 🛡️ Optional JEV: labels each email (spam, phishing, marketing…) and hides likely prompt injection. - 🔐 One bearer token guards everything except /health, plus an optional read-only token. - 🧹 Optional retention: an hourly job deletes mail older than the days you set. - 🚀 One command deploy that sets up the database, storage, DNS and routing for you.
Read skills/agents-mail/SKILL.md first: it covers the tools, the curl fallback, the safety rules for untrusted email, and setup. Install it for your client with:
- Setting this up for a user: ask which domain to use, warn that Email Routing takes over its MX records, then run the 3 deploy steps in a terminal the user can answer. The first run asks for the sender and JEV; once apps/worker/.prod.vars exists, yes y bun run deploy runs unattended. It also says yes to taking over MX, so after changing the domain in AGENTSMAILFROM, run it with a person again. Done
