Tools

• create_inbox ~240 tokens
  Invent a fresh, unused disposable email address you can give out immediately. Nothing is created or reserved server-side — an address exists as soon as mail arrives at it — so this never fails and needs no account. Public domains: grabmail.io, mixozia.com, linqmail.com. With a paid key sent as Autho
• delete_message Deletes data · ~94 tokens
  Remove a message now rather than waiting for it to expire. Idempotent.

• wait_for_message ~286 tokens
  Blocks until a new message arrives at the address, then returns it in full — the tool to use after submitting a sign-up form. Waits at most 25 seconds and then returns with timed_out set to true; call it again to keep waiting. Optionally waits for a message from a particular sender or with particula
