Overview

Description from the maker (original English)

Disposable email inboxes for agents and tests: create an address, wait for the email. No signup.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Transport: Streamable HTTP
  • Category: Chat & email

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

ChatGPT connects only to servers on the internet:

  1. Open ChatGPT on the web → Settings → Connectors (Apps)
  2. Press Create or Add (some plans need Developer mode under Advanced first)
  3. Paste the address below, give it a name and save
  4. If it asks you to sign in, sign in with the maker

Menu names can differ slightly by plan and over time.

Your choice stays on this device in a cookie; no account needed.

Common questions

Is receivemail.dev safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.1) reached the registry 4 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

README from the maker

Open the README

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

receivemail.dev

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.

How it works

# create a mailbox (default: expires in 15 min)

curl -X POST https://receivemail.dev/mailboxes

=> {"address":"a1b2c3d4e5f6@receivemail.dev","expiresAt":"...","secret":"..."}

trigger your own app's email to that address, then poll:

curl https://receivemail.dev/mailboxes/a1b2c3d4e5f6@receivemail.dev/messages \ -H "Authorization: Bearer "

=> {"address":"...","messages":[{"from_address":"...","subject":"...","body_text":"..."}]}

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.

Endpoints

EndpointDescription
POST /mailboxesCreate a new address. Optional {"ttlMinutes": 1-60} body, default 15. Public, no token required.
GET /mailboxes/:addressMetadata (created/expiry). Requires the mailbox's own secret as a Bearer token.
GET /mailboxes/:address/messagesLast 50 messages, newest first. Same secret.
GET /mailboxes/:address/wait?timeout=25&since= Long-poll: returns the newest message newer than since as soon as one arrives, or {"timed_out":true} after timeout seconds (max 25). Same secret.

Limits

  • 20 mailbox creations/minute per IP, 5,000/day globally.
  • 60 minutes max mailbox lifetime — this is for short-lived test flows, not a permanent inbox.
  • Messages are pruned 24h after their mailbox expires.

Free to use, no API key needed to create a mailbox.

Architecture

Fully serverless, no shared infrastructure with anything else:

  • Cloudflare Email Routing on the receivemail.dev zone receives the actual mail.
  • Cloudflare Worker (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.
  • D1 (schema.sql, schema_v2.sql, schema_v3.sql) — emails, mailboxes (with a per-mailbox secret for capability-style read access), rate_limits.

Local development

npm install

npx wrangler dev # local dev server npm run deploy # wrangler deploy

Requires a Cloudflare account with the receivemail.dev zone, Email Routing configured, and a D1 database bound as DB in wrangler.toml.
