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 | $0.01864 | $0.01864 |
| Opus 5 | $0.00932 | $0.00932 |
| Sonnet 5 | $0.00373 | $0.00373 |
| Haiku 4.5 | $0.00186 | $0.00186 |
Grade A, and why
france-data-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 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.
How it starts
The opening of the file, as written. The whole thing — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md — france-data-mcp
Conventions + workflow + release, en règles de tête (budget ~1 000 mots). Le détail — post-mortems chiffrés, patrons SQL, checklists — vit dans les skills du projet, chargés à la demande :
mcp-conventions,ingestion-crons,db-gotchas,release-process(.claude/skills/). VoirREADME.mdpour l'usage MCP,CHANGELOG.mdpour l'historique.
Override CLAUDE.md global — Déploiement : Merge sur
mainet deploy production = manuel, validation Cyril requise. Le défaut universel « Claude merge+deploy auto quand tout est vert » ne s'applique PAS ici. Justification : données santé prod (FINESS / RPPS / Ameli), HDS, audit trail ; les régressions silencieuses prouvées prod (matview OID, GiST partiel découplé, ban_join keyset) avaient toutes des tests verts au commit. Claude prépare la PR, Cyril valide et merge.
Stack
TypeScript strict + Vercel serverless (api/) + Supabase PostGIS + pnpm + tsup + vitest + biome.
Lib (src/, publiée npm) ≠ Endpoint (api/, hosté Vercel) — conventions distinctes (skill mcp-conventions).
Workflow
pnpm test:unit # rapide, sans DB
pnpm typecheck && pnpm lint # avant tout commit
pnpm test # complet, nécessite `pnpm db:start`
pnpm release # release semi-auto (voir scripts/release.sh)
CI GitHub Actions vérifie typecheck (2 tsconfigs) + biome + tests + Supabase local.
test/test:integration portent --no-file-parallelism : plusieurs fichiers *.integration.test.ts partagent la table mutable rpps_staging (recréée par ingest_create_rpps_staging()) — l'exécution parallèle des fichiers les clobbe mutuellement. test:unit exclut les intégration → reste parallèle. Tout nouveau test d'intégration touchant rpps_staging DOIT re-seed en tête de chaque it + ré-asserter le peuplement (pattern ban-eligibility-skipscan.integration).

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.

france-data-mcp CLAUDE.md is an instructions file published in the GitHub repository cturkieh/france-data-mcp (3 stars, last pushed 3d ago), licensed MIT. It adds 1,864 tokens to every session, about $0.0093 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.
