_ is it live, free and safe measured by this hub
Is jaryo live?
Yes — it answered the hub's last check (checked 19h ago). It answered 100% of checks over the last 30 days.
Is jaryo free to use?
Partly — some of its tools are open, others need a key or payment.
What tools does jaryo have?
7 tools: verify_company, match_companies, search_companies, list_sources, resolve_company, get_company, list_company_records.
Is jaryo safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

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.

  • list_sources open 19h ago

    Catalog of Korean public data sources Jaryo uses, with license, redistribution status and update cadence. No key needed.

  • verify_company unknown never probed

    Start here. Verify a Korean corporation by name, business registration number (10 digits), corporate registration number (13 digits), DART code (8 digits) or stock code (6 digits): does it exist, its National Tax Service status (active / suspended / closed, with the date it was checked), official numbers, Korean and English names, address, industry and sources. Up to 10 matches, best-known company first; more_matches=true means add the business number or city to narrow. Each match has match_type; name results also have rank_reason (why it is in that place) and the response has ranking. industry.ko / industry.en are official KSIC names (11th revision); industry.tax_business_type is a tax classification, not KSIC. Corporations only — individual businesses are answered as not supported. No scores or judgements. No key needed. (한국 법인 확인)

  • match_companies unknown never probed

    Match up to 1,000 rows of your own company list to official Korean identifiers. Each row is a string or an object/array of cells — a company name and/or a business registration number (10 digits), corporate registration number (13), DART code (8) or stock code (6), in any order. Returns per row: result (matched / ambiguous / not_found / not_supported / invalid), match_type, entity_id, official numbers and the official English name; several equally good candidates are answered as ambiguous, not guessed. Identifiers only (tax status is free at verify_company). Rows are not stored. Each row uses one unit of your daily limit. Requires a Jaryo API key (free: https://jaryo.org/keys/). (회사 목록 맞추기)

_ 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 d4b59bd9bf4b5ea5.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/d4b59bd9bf4b5ea5/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.
