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 | $0.03547 | $0.03547 |
| Opus 5 | $0.01774 | $0.01774 |
| Sonnet 5 | $0.00709 | $0.00709 |
| Haiku 4.5 | $0.00355 | $0.00355 |
Grade A, and why
zaim-api-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 7d 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.
How it starts
The opening of the file, as written. The whole thing — 374 lines — stays where its author put it; the contents beside it link to each section on GitHub.

- 言語: TypeScript
- フレームワーク: MCP SDK (@modelcontextprotocol/sdk)
- バリデーション: Zod
- 実行環境: Node.js 22+
- テストフレームワーク: Vitest
- 認証: OAuth 1.0a

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.

zaim-api-mcp CLAUDE.md is an instructions file published in the GitHub repository yone-k/zaim-api-mcp (8 stars, last pushed 1y ago), licensed MIT. It adds 3,547 tokens to every session, about $0.0177 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
