Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00686 | $0.00686 |
| Opus 5 | $0.00343 | $0.00343 |
| Sonnet 5 | $0.00137 | $0.00137 |
| Haiku 4.5 | $0.00069 | $0.00069 |
Grade A, and why
bitbank-lab-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to bitbank-lab-mcp CLAUDE.md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

アーキテクチャ
- スキーマ変更は
src/schema/配下の Zod 定義を単一ソースとする(src/schemas.tsは re-export) - 全ツールは
Result<T, M>パターン(ok()/fail())で返す lib/に共通ユーティリティがある処理は、外部ライブラリの直接利用や自前実装をせずlib/を使う- 対応ペアは JPY 建てのみ(表示層が円前提)。非 JPY 建て対応は別途、表示層の quote 通貨移行が前提(
lib/validate.tsのALLOWED_PAIRS、ガードはtests/lib/validate.test.ts)。 - stdio 以外のトランスポート(HTTP 等)を
src/server.tsに足す変更は、同じ PR でconfirmation_tokenの session / principal 束縛を実装しない限り入れない(ADR-0007 判断事項 B)。 トークンの HMAC ペイロードはaction + params + expiresAtのみで session 束縛が無い (署名鍵の per-process nonce はプロセス境界を閉じるだけで、HTTP では 1 プロセスに複数 セッションが同居するため session 境界には効かない)。UI スナップショットの キーと MRTR の bind は未設定 sessionId を空文字に畳んでいる。stdio は 1 接続なので今日は無害だが、 HTTP を足した瞬間に別クライアントからの execute を弾けなくなる。ガードはtests/http-transport-tripwire.test.ts(必要な実装内容が失敗メッセージに出る)。

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
