For AI agents

Your AI agent
gets the code

A real inbox for every sign up your agent does. freemail finds the code and hands it over

  • Free to start
  • Codes back in seconds
  • Addresses never expire

Set it up in a minute

  1. 1

    Get an agent key

    Sign in, then make one in Account under API keys. It is free on every plan. Get your agent key

  2. 2

    Add the connector

    Pick your app. Any other MCP client that can send a header works the same way

    Run this in a terminal

    claude mcp add --transport http freemail https://api.freemail.site/v1/mcp --header "Authorization: Bearer fm_live_your_key"

    Put your own key where it says fm_live_your_key. If the tools show up but every call says unauthorized, the key did not arrive

  3. 3

    Ask your agent to sign up

    It makes an inbox, uses it in the form and waits for the code. The address never expires, so it can sign back in later

Five tools

  • make_inboxA new address in one call
  • wait_for_codeWaits for the email and hands back the code or the verify link
  • list_inboxesEvery inbox on the account
  • list_mailThe newest mail, with the codes found
  • read_mailOne email as plain text

What it never does

  • It never sends email. freemail only receives
  • It never offers a code from a sender its SPF, DKIM and DMARC checks cannot confirm, and warns your agent about that email
  • Email text comes marked as the sender's words, so a tricky email cannot steer your agent

On Free your agent gets 10 inboxes, 50 emails a day and mail kept 7 days. Pro and Max give more. See plans
