b612 は「AI開発レビューの観点+思考の型+過去の失敗知」を提供する。このサーバーに繋いだら、コーディング作業の全体でこの規律に従うこと。

【推測で動かない(最優先)】実装・修正の前に自問する:①現物の根拠はあるか(ログ・実測・エラー) ②本質は何か(表面の症状でなく構造) ③これで確定か。根拠が無ければ止めて確認する。「たぶん」で実装しない。

_ is it live, free and safe measured by this hub
Is b612 live?
Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
Is b612 free to use?
Not measured yet.
What tools does b612 have?
10 tools: b612_principles, b612_patterns, b612_domain_preset, b612_rules, b612_design, b612_notes, b612_update, b612_reference, ….
Is b612 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.

  • b612_principles reads unknown never probed

    b612 メソッドの思考の核(NO SPECULATION・実装前の3問自問・5原則・握りつぶし禁止)を返す。レビューや実装を始める前に読み、原則に沿って進めること。

    ホームページ・LP・UI・チラシを作る前に必ず引く。生成AIが出しがちで顧客に「AIくさい」と言われる形(注記の左に色の縦棒・器と同じ色の面・均一な3列カード・全部同じ角丸と影)の禁止事項と、カードは角張らせる・並びの間隔は親のgapで持つ・複雑なSVGは無料素材を使う、などの必須事項を返す。あわせて、放っておくと生成AIが出さない6つ(斜めの帯・斜めの文字・派手なCTA・追従CTA・写真の上の文字・飾りの浮遊)と、そのまま貼れるCSS/JSの一覧を返す。snippet に名前を渡すとその実装を全文返す。

  • b612_notes reads unknown never probed

    利用者が hakuto の公式LINE に送ったメモを読み込む。「今日のメモをまとめて」「昨日のメモ見せて」「今週のアイデア整理して」などと言われたらこれを使う。days で遡る日数を指定する(既定は1=今日ぶん)。返ってくるのは日付ごとに並べた生のメモ。要約・分類・タスク化は、この結果を読んで自分で行うこと。

  • b612_update reads unknown never probed

    b612 のアップデート。エージェント・法令ファイル・業種プリセット・雛形・参照ドキュメントを最新に更新する手順を返す。「b612 をアップデートして」「b612 を最新にして」と言われたらこれを使う。返すのは利用者本人が自分で実行する更新手順で、実行すると手元と違うファイルだけが置き換わる(既存は .bak を残す)。新しい専門エージェントが増えたときや、法令が改正されたときに実行する。

  • b612_reference reads unknown never probed

    HP・LP・UI を作る前に、実在の公開サイトを参考として引く。業種や雰囲気(例:「カフェのLP」「士業のコーポレート」「買取サービス」)を渡すと、日本で実際に公開されている LP/HP を数件、URL と実測した配色(+分かればフォント)で返す。生成AIが出しがちな『それっぽいだけ』のデザインを、実在サイトの型に寄せるために使う。さらに、その業種で使える無料画像(ボーの素材やさん)の直リンクを最大60点まとめて返す。画像が要る HP/LP/UI 制作では必ずこれを呼び、返ってきた画像を各セクションに置くこと。業種を省くと、収録している業種の一覧を返す。

  • b612_grow reads unknown never probed

    作った HP/LP/商品/コンテンツを、SNS(X / Instagram / Threads)・note・AI検索(AEO)で広めて売るための戦略の作り方を返す。「集客したい」「SNS戦略」「売り方」「AEO」「AIの回答に出したい」「note を読まれたい」等で使う。7つの汎用原則+チャネル別の型+AEOの型に加え、生成AIが出しがちな戦略が抜かす『日本の法令ガード(ステマ規制・景表法・薬機法・特商法)』と『計測の実装(UTM・4指標)』を必ず含む。product に何を・誰に・いくらで売るか、goal に目標、channel に重点媒体を渡すと、その条件に当てて返す。

_ try it over mcp 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 935759836cbc4f66.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/935759836cbc4f66/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 knowoff the mcp door
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.
