_ usage and payments 30 days

Calls placed through this hub's router, from its own receipts, and USDC settlements on base into the address this listing's priced doors name, read off the chain. Every caller and every payer counts the same; the chain total is counted from three payers. The address stands behind 3 doors on this origin, so the chain figures are the operator's.

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

6 never probed 0 of 6 classified

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.

  • check_korea_import_requirements unknown never probed

    Check what Korean customs clearance requirements apply to a product by its 10-digit HS code. Goods that need an unmet approval are held or returned at Korean customs. Returns which statutes require clearance, which agencies can approve (often several, any one of which suffices), the certificate to obtain, and each requirement's condition quoted from the governing notice (Korean original, which is authoritative) — plus tariff rates for imports. Data: Korea Customs Service and the Ministry of Government Legislation. Fact lookup only — not a legal customs determination; whether a condition applies to your product is not decided here. Test code 8516710000 (coffee makers) is free.

  • verify_korean_business reads unknown 3h ago

    Verify that a Korean business registration number matches the provided representative name and opening date. Use for KYB / due-diligence before transacting with a Korean company. Returns match result plus current status.

  • check_korean_business_batch reads unknown 15h ago

    Screen a list of up to 100 Korean businesses in a single call by their 10-digit business registration numbers (사업자등록번호). Returns one entry per input number (order preserved) with registration status, tax type, and any public-procurement debarment ("부정당업자 제재") on record — a company can be perfectly active and still barred from public contracts. The summary counts how many are currently debarred. Use this for supplier, vendor or customer list screening instead of repeated single checks. Recently checked numbers may be answered from a cache up to 24 hours old (marked "cache": true). Sources: Korea National Tax Service, Public Procurement Service.

  • check_korean_business_status reads unknown 15h ago

    Check the registration status of a Korean business by its 10-digit business registration number (사업자등록번호). Returns whether the business is active, suspended, or closed, plus tax type. Data source: Korea National Tax Service, real-time. The number 1248100998 (Samsung Electronics) is exempt from the daily free tier, so you can exercise this tool while building without spending your allowance.

  • find_korean_business reads unknown 15h ago

    Find a Korean company by name (English or Korean) when you do not know its 10-digit business registration number — the number every other tool here needs. Returns ranked candidates with a confidence score and discriminating evidence (registration status, tax type, region), because a name can match several distinct companies: "Samsung Electronics" matches four. Sources: DART (disclosure filers, English names) and the Public Procurement Service registry (small businesses).

  • check_korea_import_requirements_batch unknown never probed

    Screen a product catalog for Korean import restrictions in one call. Submit up to 100 HS codes and get back what is restricted, with the statute, the approving agencies and the certificate required for each. Restricted codes come first, then codes that could not be checked, then clear ones. Invalid codes are listed in summary.invalid_hs and not counted. Use before opening a Korea shipping lane or listing a catalog for Korean buyers. Fact lookup only — not a legal customs determination.

_ 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 1c2ea248ca29289b.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/1c2ea248ca29289b/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
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.
