Tools (11)

As the server listed them on Oct 25, 2026. Descriptions are the server’s own words; hidden characters are shown as [U+…].

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.
delete_inbox
Delete an inbox: revokes the token and erases stored mail.
delete_webhook
Remove the inbox webhook.
get_inbox
Read an inbox: address, status, expiry, limits, and usage.
get_message
Fetch one message with parsed text, HTML, and attachment download URLs.
get_service_info
Read the Machine Inbox service instructions: pricing, payment rails, endpoints, and limits.
get_verification_code
Extract the newest one-time verification code or confirmation link from inbound mail. Ideal for signup and login flows.
get_webhook
Read the inbox webhook state: URL, delivery counters, and whether it is disabled. The secret is only returned by set_webhook.
list_messages
List messages in an inbox, newest first. Pass after=<newest createdAt seen> to poll for only new mail.
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.
