Registry code: 9271f56fe84acb8f

api record

burofax.onmax.me sends a letter the user has written or approved to an address in Spain, as a Correos burofax (acuse de recibo + copia certificada) or as a Notificados certified notification (a trusted third party, not Correos). It is a sending service, not a law firm: never present the text as legal advice and never claim legal validity is guaranteed.

Typical flow: quote_burofax if the user asks about price; check_spanish_address for the recipient (and the sender if in Spain); show the full letter text to the user and get explicit approval; then create_burofax_draft and show the review link.…

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • quote_burofax open 8h ago

    Use this when the user asks how much it costs to send a burofax or a certified letter to an address in Spain, or wants to compare delivery options before writing it. Returns the all-in price in EUR of both options for the given length, and what each includes: (1) Burofax de Correos with acuse de recibo and copia certificada; (2) a certified notification by Notificados, a trusted third party (tercero de confianza) that is NOT a Correos burofax. Always pass that distinction on to the user. Give pages if known, otherwise text_length (characters of the letter body) for an estimate; with neither, quotes one page. Does not send or reserve anything. Do not use it to create the letter; use create_burofax_draft once the text and addresses are approved.

  • create_burofax_draft unknown never probed

    Use this when the user has approved the final text of a letter to send as a burofax to an address in Spain and has given both postal addresses. The user writes or approves the text; this service does not give legal advice, so pass the body exactly as approved, without adding legal claims. Show the full text to the user and get approval before calling. Renders the exact A4 letter (sender, recipient, place and date, subject, body, signature line) as a PDF in Spanish, stores it as a draft and returns the page count, the price of each option and a review_url. Nothing is sent and nothing is charged by this tool: after calling it, show the review_url and tell the user that the letter goes out only after they pay on that page. Never ask for or include DNI/NIE/NIF or other ID numbers. Do not use to check prices (use quote_burofax) or to track a paid letter (use get_burofax_status).

  • check_spanish_address unknown never probed

    Use this when the user gives a recipient (or sender) postal address in Spain, before creating a burofax, to catch mistakes that would stop delivery. Checks offline: required fields (name, street, postcode, city), the 5-digit código postal in range 01000–52999, and that the province matches the postcode's first two digits. Returns normalised fields (with the official province) and a list of problems with messages for the user. It does not confirm that the street or person exists. Do not use for addresses outside Spain.

  • get_burofax_status unknown 8h ago

    Use this when the user asks whether their burofax was paid, sent or delivered, or wants the certificate. Takes the reference the user has: the order reference (BFX-XXXX-XXXX-XXXX-XXXX, from the receipt email) or the draft reference / review link returned by create_burofax_draft. Returns the current status and a dated timeline (draft created, paid, accepted by the operator, delivered, certificate available) and a link to the status page. Read-only. Do not use to create or change a letter.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 9271f56fe84acb8f.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/9271f56fe84acb8f/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
80%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
