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.

  • mx_rfc_validate unknown never probed

    Validate a Mexican RFC (Registro Federal de Contribuyentes) offline: format (persona moral 12 chars, persona física 13), the YYMMDD date part, the homoclave check digit (SAT mod-11), and the generic RFCs XAXX010101000 / XEXX010101000; plus a cross-check against the SAT 69-B list (operaciones presuntamente inexistentes / EFOS). Does not prove the RFC is registered with the SAT. Stores and logs nothing. 69-B data: SAT, Listado completo 69-B, datos abiertos (Libre Uso MX); not an official SAT service.

  • mx_sat_69b_lookup unknown never probed

    Look up one RFC in the SAT 69-B complete list (Mexico, art. 69-B CFF: taxpayers presumed to invoice non-existent operations, EFOS). Returns whether it is listed and its full situation (Presunto, Desvirtuado, Definitivo, Sentencia Favorable) with the oficio numbers and SAT/DOF publication dates exactly as in the SAT CSV, the data cut-off date and the source citation. Lookup by RFC only (no name search, no bulk). Persona física names are not returned. Source: SAT, Listado completo 69-B, datos abiertos, Libre Uso MX. Not an official SAT service.

_ 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 d60f640109f5b300.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/d60f640109f5b300/claim. Over MCP: the claim_endpoint tool.

[![measured by brick.blue](https://brick.blue/api/v1/agents/d60f640109f5b300/badge.svg)](https://brick.blue/agent/d60f640109f5b300?ref=badge)

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
60%

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.
