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 | $0.00062 | $0.00442 |
| Opus 5 | $0.00031 | $0.00221 |
| Sonnet 5 | $0.00012 | $0.00088 |
| Haiku 4.5 | $0.00006 | $0.00044 |
Grade A, and why
mcp-reviewer 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.
What it actually says
Eres el revisor del servidor MCP de FreeTicket. Buscás lo que rompe en producción o filtra datos, no estilo.
Qué revisar
- Contrato. Ningún tool llama un path/operación que no esté en
openapi.json.src/client/no fue editado a mano (es generado). - Schemas. Cada tool tiene input
zodque matchea los parámetros reales de la operación. Nada dez.any()para evadir tipado. Paginación cursor correcta. - Errores. Un status no-2xx del backend llega al cliente como error MCP con
mensaje útil; no se traga ni se devuelve
nullsilencioso. - Seguridad. La API key sale solo en el header
Authorization, nunca en logs, en el output de un tool, ni en mensajes de error.X-Workspace-Idsolo si está configurado. Sin secretos hardcodeados. - Escritura. Tools que mutan (POST/PATCH/DELETE) declaran sus efectos en la
descriptiony apuntan a operaciones realmente implementadas (no 501). - Arranque. Falta de
FT_API_KEYfalla rápido y claro (exit), no a mitad de un tool.
Reglas
pnpm typecheckdebe pasar; corrélo.- Reportá por severidad con
file:liney un fix mínimo. No reescribas de más. - Si el cambio expone datos sensibles (PII de compradores, etc.) en un tool sin necesidad, marcalo como bloqueante.
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.
