Disposable email inboxes for agents and tests: create an address, wait for the email. No signup.
receivemail.dev's hosted MCP server (receivemail.dev), published by receivemail.dev; no sign-in required; Streamable HTTP; 3 tools.
No AI overview yet: these facts come from the registry entry and the server itself.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/dev.receivemail%2Freceivemail/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}A disposable, real-receiving email address via one API call. No signup, no SMTP setup, no account. Built for testing verification/OTP emails, signup flows, and anywhere a QA suite would otherwise need to burn a real inbox.
Live at receivemail.dev.
The secret returned at creation is the only credential — hold onto it, there's no account/login. Any address at @receivemail.dev accepts mail even if never explicitly reserved (same as any disposable-inbox provider), but only a reserved address has a secret to read it back with.
Free to use, no API key needed to create a mailbox.
Fully serverless, no shared infrastructure with anything else:
receivemail.dev zone receives the actual mail.src/index.ts) — an email() handler parses and stores incoming mail via postal-mime; a fetch() handler serves the REST API and the landing page (src/landing.ts); a scheduled() handler runs a daily cleanup of expired mailboxes/old mail/rate-limit buckets.schema.sql, schema_v2.sql, schema_v3.sql) — emails, mailboxes (with a per-mailbox secret for capability-style read access), rate_limits.Requires a Cloudflare account with the receivemail.dev zone, Email Routing configured, and a D1 database bound as DB in wrangler.toml.
sms-florin — same idea, for SMS/OTP verification codes instead of email (rents a real UK phone number).

Create a disposable mailbox
Create a disposable receivemail.dev email address that receives real mail. Returns address, expiresAt and secret; keep the secret to read the mailbox. Free without a key (up to 60 minutes); with a paid key on the MCP connection, up to 1440 minutes and an extracted otp field on messages.
ttlMinutesWait for the next email
Wait up to 25 seconds for an email to a mailbox made with create_mailbox. Returns {timed_out:false, message:{from_address, subject, body_text, received_at}} or {timed_out:true}; call again on timeout. Pass `since` (ISO 8601) to ignore mail you've already seen.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
