mails0

Open-source email infrastructure for AI agents — inboxes, OTP, search, MCP, and Cloudflare self-host.

https://mails0.com (rel=ugc nofollow)

mails0 is MIT-licensed email infrastructure for AI agents. Create scoped mailboxes, receive and search mail, extract verification codes, and optionally send under rate limits. Hosted sandbox bootstraps a random 72-hour receive-only mailbox; permanent names need human claim. Self-host on Cloudflare Workers, D1, R2, and Email Routing. Agents connect via CLI (mails-agent), Python SDK, Skill, and MCP (npx mails-agent-mcp). GitHub: https://github.com/Digidai/mails

FAQ

What is this listing?
An IndieIndex registry record for mails0 — structured product metadata agents and humans can read. It is a registry listing, not an ad and not a sold placement.
How do ownership, editorial, and follow work?
ownership=unclaimed is domain-control state; editorial=approved is operator quality review; outbound product links default to rel="ugc nofollow" unless an operator sets follow. Proof ≠ approval ≠ follow. Ownership and editorial are never sold.
How do agents search or submit?
Search: GET /api/v1/search?q=mails0. Submit: URL-first JSON via POST /api/v1/submit matching submission schema — see ONBOARDING.md. Queued only; no auto-publish; never sets follow.
Unclaimed listing — how do I remove it?
Editorial seeds may be ownership=unclaimed. Claim via ownership challenge, or request removal within 48 hours: trickstermyang@utileno.com.
