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 | $0.00391 | $0.00391 |
| Opus 5 | $0.00196 | $0.00196 |
| Sonnet 5 | $0.00078 | $0.00078 |
| Haiku 4.5 | $0.00039 | $0.00039 |
Grade A, and why
mcp-crypto-price AGENTS.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 4d 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.
What it actually says
AGENTS.md
MCP server exposing CoinCap v3 cryptocurrency data via STDIO and Streamable HTTP transports. TypeScript, Node.js 22.14+, pnpm, Zod, Vitest.
Critical rules
COINCAP_API_KEYis required at runtime — never commit it.- One file per tool in
src/tools/; each exports a*Schema(Zod) andhandle*(args). Wrap.parse()in try/catch returningisError: trueon validation failure. - Register new tools/resources/prompts in
src/index.ts. - Cache lives in
src/services/coincap.ts(CACHE_TTL= 60s) — don't bypass it for CoinCap calls. - Commits must be SSH-signed and follow Conventional Commits (
feat:,fix:,chore:...). Releases are automated via semantic-release on push tomain. - Don't add code-style rules here — Prettier (
.prettierrc) and ESLint (eslint.config.js) own formatting/linting. - Use
pnpm(not npm/yarn). Runpnpm types:checkandpnpm testbefore considering work done.
Entry points
- STDIO:
src/index.ts→dist/index.js - HTTP:
src/http.ts→dist/http.js(key via?COINCAP_API_KEY={key})

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.
