Temp Mail MCP: disposable inboxes for your AI agent

Testing a sign-up flow with an AI agent usually stalls at the confirmation email. Temp Mail's MCP server gives the agent disposable inboxes, so it can read incoming messages and pick out the verification code. ContextGate connects it to Claude, ChatGPT and Cursor, and every inbox read lands in Activity next to the rest of the agent's calls.

Give your AI agent a Temp Mail inbox

  1. 1Click Connect Temp Mail free and sign in with your Temp Mail account.
  2. 2A test usually needs only an inbox and a way to read it. When the tool list appears after connecting, everything is on: keep those and switch off anything else.
  3. 3Add ContextGate to your AI app as a connector or MCP server. The steps for each app are on the Works with page.
  4. 4Ask your AI app for a disposable address, use it on a sign-up form you're testing, then ask for the verification code. Activity shows each call it made.

What an agent can do with a throwaway inbox

  • Get a disposable email address to sign up for a staging account without using a real mailbox.
  • Read the messages that arrive in the inbox, including confirmation emails.
  • Pull a verification code out of an email so the agent can finish a sign-up on its own.

Keep track of codes and inboxes

  • Activity records every Temp Mail call, so you can trace which inbox an agent read and when.
  • Switch off any Temp Mail tool you don't need; it's hidden from AI apps and refused if called.

ContextGate sees the calls that go through it. If your agent fills in the form with a built-in browser tool, that part isn't recorded.
