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_courses open 55m ago

    Use this when the user asks how to study Japanese or prepare for a JLPT level with Japanese Skills · 言の葉, what the site has, or what is free. Lists the free study library (counts and links), the JLPT practice levels (Starter and N5 free; N4–N2 with a subscription or pass), and the 15 courses with their level, number of lessons, how many are free and their links. With course, lists that course’s lessons (title, free or not, link). States the published prices only as the pricing page does, with its link.

  • lookup_word unknown never probed

    Use this when the user asks about a Japanese word: what it means, how to read or pronounce it, its pitch accent, whether it is a godan or ichidan verb, how to conjugate it (te-form, past, polite, potential…), or how to say something in Japanese. Searches the 9,040 JLPT words (N5–N1) of Japanese Skills · 言の葉 by the word in kanji or kana (食べる, たべる), romaji (taberu), or a meaning in English, Chinese or Korean (eat, 吃, 먹다). Each result has the reading, JLPT level, the meaning in the user’s language, the pitch accent (accent number, type and H/L pattern), the word class and conjugation table where the site has one, an example sentence with its translation where the site has one, links to the site’s recordings in two voices where a free one exists, and the word’s page. Shows a word card in chats that display app UI. Returns no results when the word is not in the list. Not for translating whole sentences.

  • find_grammar unknown 55m ago

    Use this when the user asks about a Japanese grammar pattern or particle (〜てもいい, ために, ば vs たら, は and が), what it means, how it is used, an example of it, or how to say something with a pattern. Searches the site’s 828 grammar points (N5–N1) by the pattern in Japanese or romaji, or by its meaning in the user’s language. Each result has the pattern, JLPT level, meaning in the user’s language, an example sentence with translation, a link to the site’s free recording of the example where one exists, and the grammar page; plus the site’s course lessons whose titles match, with links and whether each is free.

  • lookup_kanji unknown 55m ago

    Use this when the user asks about a kanji (a Chinese character used in Japanese): which JLPT words use it and how it is read in them, at which JLPT level it first appears, or where to learn it. For each kanji given (up to five), lists the words in the site’s JLPT word list that contain it, easiest level first, with reading, level and meaning in the user’s language; how many words use it and the lowest level among them; and the site’s kanji lessons that teach it (title, link, free or subscription). Gives no on’yomi/kun’yomi table or stroke order: the readings are those of the words.

_ 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 83d53929056e7e74.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/83d53929056e7e74/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
80%

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.
