Registry code: 6a6d87b3022c03bd
Shirabe exposes Japan-specific APIs (calendar lookup, address normalization, Japanese name splitting, and corporate-number lookup/search) for AI agents; a cross-identifier enrich tool is added as it goes live. Call tools/list to see available tools.

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.
distinct, expensive to fake
successful, last 30 days
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
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.
lookup_calendar reads unknown 12h ago
Look up Japanese calendar information for a given date: Rokuyo (six-day cycle such as Taian/Butsumetsu), Rekichu (almanac notes), Eto (sexagenary cycle), 24 solar terms, and purpose-based auspiciousness scores. Useful when an AI agent needs canonical Japanese calendar facts (e.g. choosing an auspicious date for a wedding or ceremony). Source: Shirabe Calendar API (shirabe.dev).

Look up a Japanese company by its 13-digit corporate number (法人番号) against the National Tax Agency (NTA) corporate-number registry. Returns the registered trade name, head-office address, change history and other public fields as JSON, plus mandatory NTA attribution. Useful when an AI agent already has a corporate number and needs canonical company facts (e.g. validating or enriching a B2B record). To go the other way (company name → number), use corporation_search. Source: Shirabe Corporation API.

Split a Japanese personal name into family and given parts using IPAdic person-name POS tags (with whitespace/length heuristics as fallback). Returns family, given, and a confidence score (0-1; warning when low). Useful for normalizing name fields in HR, CRM, or form data. Source: Shirabe Text API.

Search the Japanese corporate-number registry (National Tax Agency) by company name and return matching companies, each with its 13-digit corporate number (法人番号), registered name and address, plus mandatory NTA attribution. Handles trade-name variants (㈱ / (株) / 株式会社) via normalization. Useful when an AI agent has a company name and needs to resolve its corporate number / canonical record. To go the other way (number → company), use corporation_lookup. Source: Shirabe Corporation API.
{ "type": "object", "required": [ "name" ], "properties": { "name": { "type": "string", "description": "A Japanese company name, e.g. 株式会社テックウェル (variants like ㈱テックウェル are accepted)." } }, "additionalProperties": false }arguments 13 linesnormalize_japanese_address reads unknown never probed
Normalize a free-form Japanese address against the official Address Base Registry (ABR, all 47 prefectures). Returns the canonical form, structured components (prefecture/city/town/block/building), postal code, WGS84 coordinates, match level (0-4) and confidence, plus mandatory CC BY 4.0 attribution. Useful when an AI agent must clean or de-duplicate Japanese B2B/customer records. Source: Shirabe Address API.

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.
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.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - 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. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's id6a6d87b3022c03bd.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/6a6d87b3022c03bd/claim.

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.
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.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
