Faxer MCP Server について

Send real faxes to any US, Canadian, or international fax number from any AI assistant. The agent quotes the exact price from the document's real page count, hands the human a Stripe Checkout link (payment stays human-in-the-loop — agents never touch cards), transmits over a real fax network once payment is verified, and polls delivery status. One fax per payment; failed transmissions are refunded automatically. Pay per fax: $1.00 first page + $0.25/page. No account, no API key, no subscription. Tools: get_fax_quote, create_fax_payment, send_fax, get_fax_status.

Get the exact price to send a real fax to any US, Canadian, or international fax number via faxer.me. Call this first whenever a user wants to send, transmit, or fax a document or message. Provide document_url (a publicly downloadable PDF), cover_text (plain text that will be rendered onto fax pages), or pages (an estimated page count). Pricing is pay-per-fax ($1.00 first page + $0.25/page, returned in USD cents); no account or API key needed.

Create a Stripe Checkout payment link for a fax. Returns payment_url — give this link to the human so they can pay in their browser (agents never handle card details) — and payment_id, which you pass to send_fax after the human has paid. The price is computed server-side from the document or text. The Checkout link expires (see expires_at, ~24h); create a fresh one if the human delays.

Transmit a fax. Two ways to pay: (1) human-in-the-loop — pass the payment_id from create_fax_payment after the human has paid the Stripe Checkout link; (2) autonomous machine payment (x402/MPP) — call WITHOUT payment_id and the server replies with a payment challenge (JSON-RPC error -32042) for USDC-on-Tempo or a Stripe Shared Payment Token; pay it and retry with the credential in _meta['org.paymentauth/credential']. Either way the server verifies the payment covers the server-computed price of the actual content before sending via a real fax carrier. One fax per payment; card/Checkout and Stripe machine payments are refunded automatically if the fax fails to send or deliver (on-chain payments are refunded manually).

Check the delivery status of a fax sent with send_fax. Status 'success' means the receiving fax machine confirmed the transmission; 'inprogress'/'queued' mean it is still sending; 'failure' means it could not be delivered. Delivery typically takes 1-5 minutes; poll roughly every 30 seconds.

概要

What is Faxer?

Faxer is a pay-per-fax remote MCP server that lets any AI assistant send real faxes to US, Canadian, and international fax numbers. No account, no API key, no subscription — pay per fax: $1.00 for the first page + $0.25 per additional page.

How it works

  1. get_fax_quote — quotes the exact price from the document's real page count
  2. create_fax_payment — returns a Stripe Checkout link the agent hands to the human. Payment stays human-in-the-loop; agents never touch cards.
  3. send_fax — verifies the payment covers the recomputed price, then transmits over a real fax network. One fax per payment.
  4. get_fax_status — polls delivery status. Failed transmissions are refunded automatically.
