Use validar_nfse antes de transmitir uma DPS, classificar_servico quando a dúvida for qual código usar, e explicar_rejeicao quando o sistema nacional devolver um código. Toda resposta traz tables_version: cite essa versão, porque a mesma nota pode ter resposta diferente em versões diferentes da tabela.

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.

  • validar_nfse unknown never probed

    Confere o XML da DPS (NFS-e do padrão nacional) contra as regras oficiais de IBS/CBS e devolve o que seria recusado, com o código oficial de rejeição e o campo do XML que causou. Use antes de transmitir. Nada da nota é guardado.

  • classificar_servico unknown never probed

    A partir do item da LC 116 (ou do código de tributação nacional), do regime do prestador, do município e da data de competência, devolve os candidatos de CST e cClassTrib com justificativa, alíquotas vigentes e a fonte oficial de cada regra. Use quando a pergunta for 'qual código eu uso neste serviço'.

  • explicar_rejeicao unknown never probed

    Recebe um código de rejeição da NFS-e nacional (E0958, E0855, E0959...) e devolve o texto oficial da regra, o campo do XML a que ela se refere e se o efeito é recusar a nota. Use quando a pergunta for 'o que significa este erro'.

_ 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 93f6f0f2c221c3ad.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/93f6f0f2c221c3ad/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/93f6f0f2c221c3ad/badge.svg)](https://brick.blue/agent/93f6f0f2c221c3ad?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
70%

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.
