What it can do

Tool names and descriptions exactly as the server reported them on Nov 10, 2026. The maker wrote them, not us; we show them as plain text.

• get_service_info

  Read the Machine Inbox service instructions: pricing, payment rails, endpoints, and limits.

• create_inbox

  Request a new paid inbox. Buying requires an out-of-band payment (Stripe MPP or x402 USDC on Base); this tool returns the live HTTP 402 payment challenge plus exact instructions to complete the purchase. Standard inbox: $2.00.

• get_inbox

  Read an inbox: address, status, expiry, limits, and usage.

• list_messages

  List messages in an inbox, newest first. Pass after= to poll for only new mail.

• get_message

  Fetch one message with parsed text, HTML, and attachment download URLs.

• get_verification_code

  Extract the newest one-time verification code or confirmation link from inbound mail. Ideal for signup and login flows.

• reply_to_message

  Send an included plain-text reply to the authenticated sender of an inbound message.

• set_webhook

  Register or replace the inbox webhook: an HMAC-signed POST fires on every inbound message with metadata, extracted verification codes, and injection risk (never the body). Returns the signing secret.

• get_webhook

  Read the inbox webhook state: URL, delivery counters, and whether it is disabled. The secret is only returned by set_webhook.

• delete_webhook

  Remove the inbox webhook.

• delete_inbox

  Delete an inbox: revokes the token and erases stored mail.
