  • find_lei open 1h ago

    Looks up a company's LEI in the GLEIF database: by LEI code (with entity status, registration status, BIC and direct and ultimate parent company) or by company name (possible matches, optionally filtered by country).

  • find_peppol_participant open 1h ago

    Looks up whether a company can receive e-invoices via Peppol. Search by VAT ID (the usual Peppol identifiers are derived automatically), by a known Peppol participant ID, or by company name. Returns two parts: the Peppol Directory (where listing is voluntary) and, for a VAT ID or participant ID, the Peppol network itself (SML and the provider's SMP), which also finds companies that are not listed in the directory. 'registered' with confirmed: true (the provider's SMP lists business documents) means reachable via Peppol, with the documents it receives; 'registered' without confirmed is only an SML entry and does not prove reachability. 'not registered' only covers the identifiers looked up; the company may use another one. A name search asks the directory only.

    One report on a business partner before invoicing or delivering: VAT ID (VIES or Swiss UID register), EORI customs number (the given one, or the VAT ID tried as EORI), Peppol e-invoicing reachability, and LEI with parent company. Each part names its own source and time and has its own status; a part whose source is down says so without affecting the others. No sanctions screening.

    Use when an IBAN comes together with a BIC (SWIFT code). For IBANs without a BIC, use check_iban.

  • check_company_register unknown never probed

    Looks up a company live in the official national company register of Norway (Brønnøysund Enhetsregisteret), Czechia (ARES) or Finland (PRH / YTJ), by company number or by name (at most 10 matches). Returns name, legal form, address, registration date, state as the register says it ("active" only where the register says so, "registered" = entered and not deleted, "deleted"), bankruptcy, liquidation or restructuring as separate fields where the register publishes them, and whether the company is VAT registered (true, false, or null if the register says nothing). Each field appears only if the register provides it. Use it to confirm that a Norwegian, Czech or Finnish partner exists and is active.

  • check_registered_bank_account unknown never probed

    Checks live whether a bank account is reported to the tax authority for a given taxpayer: Poland (Ministry of Finance white list, 'Wykaz podatników VAT'; the answer carries the ministry's identifier of the query, requestId) or Czechia (register of VAT payers, published accounts, with the flag 'nespolehlivý plátce' / unreliable VAT payer). It shows whether the account is reported for this taxpayer; it does not prove who owns the account, and 'not registered' is a hint, not a judgement. Poland: the NIP and the account are sent to the ministry. Czechia: only the DIČ is sent to the register; the account is compared locally with the published list.

  • verify_receipt unknown never probed

    Checks whether a receipt from this service is genuine and unchanged, using MDB Group's published public keys (https://b2b.mdb-group.info/.well-known/mdb-receipt-keys.json). Pass the receipt object (or the whole tool result that contains it, or its JSON text). Optionally pass the result it belongs to, to confirm that the result was not changed either. Answers "valid" (genuine and unchanged) or "invalid" with a reason: UNKNOWN_KEY_ID, BAD_SIGNATURE, MALFORMED, RESULT_MISMATCH or MALFORMED_RESULT (the given result could not be read). "unavailable" (KEYS_NOT_CONFIGURED) means this server has no usable key right now and could not judge the receipt; that is not "invalid". A genuine receipt proves that this service delivered the result at that time, not that the official source said so (except the VIES consultation number).

_ 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 db762ebf9f45bfb3.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/db762ebf9f45bfb3/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/db762ebf9f45bfb3/badge.svg)](https://brick.blue/agent/db762ebf9f45bfb3?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
100%

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.
