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 | $0.11389 | $0.11389 |
| Opus 5.5 | $0.04556 | $0.04556 |
| Sonnet 5.5 | $0.02278 | $0.02278 |
| Haiku 4.5 | $0.01139 | $0.01139 |
Grade A, and why
medical-terminologies-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 9d 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 — 280 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Commands
npm run build # esbuild bundle: src/index.ts -> dist/index.js (Node, ESM, node20)
npm run build:worker-lib # esbuild bundle: src/worker-lib.ts -> dist/worker-lib.js (the Worker's view of the package)
npm run build:all # both bundles
npm start # node dist/index.js (runs the MCP server over stdio)
npm run dev # build + start (stdio)
npm test # vitest run (skips integration tests by default)
npm run test:watch # vitest in watch mode
npm run typecheck # tsc --noEmit (strict; not invoked by `npm run build`)
node scripts/smoke-mcp.mjs # smoke against the hosted Worker (initialize/tools/list/calls)
node scripts/smoke-mcp.mjs --stdio # same smoke over local STDIO (requires npm run build)
node scripts/smoke-mcp.mjs --sonda # only asks the sources (RxNav, clinicaltables, MeSH, WHO) whether they are serving (exit 0/2) — read a red deploy with it
The smoke runs on criarSmoke from @sbissoli/mcp-live-source (dev): a tool that answers
isError unexpectedly triggers a direct probe of the source(s) that check names
(sondas: ["rxnav"], ["clinicaltables"], ["mesh"], ["who-token", "who-api"]; bundled
CID-10 and ICD-10→ICD-11 checks declare sondas: []); source down = ::warning title=Fonte indisponível, exit 0 (the deploy step stays green); source serving = red with the tool's
text. A check that throws (assertion, HTTP, JSON-RPC) is a deploy defect and never probes.
The who-api probe carries a bearer token when WHO_CLIENT_ID/WHO_CLIENT_SECRET are in
the environment (the deploy job passes the repository secrets): 2xx JSON = serving, 401/403
= the WHO refusing the credential the server uses = down (recusaEhFora, mcp-live-source
0.3.1, warning). Without credentials (local run) it can only expect the 401 (every ICD-11
resource needs a token; a 4xx without an HTML page is the origin standing up).
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.

medical-terminologies-mcp CLAUDE.md is an instructions file published in the GitHub repository SidneyBissoli/medical-terminologies-mcp (16 stars, last pushed 4d ago), licensed MIT. It adds 11,389 tokens to every session, about $0.0456 per session on Opus 5.5. 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 2026-08-30.
