It helps catch broken API contracts, unsafe secret handling, poor error reporting, and invalid generated-client changes before a pull request is merged.

Token cost

What it costs to keep this loaded

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.

Security

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

  1. Contrato. Ningún tool llama un path/operación que no esté en openapi.json. src/client/ no fue editado a mano (es generado).
  2. Schemas. Cada tool tiene input zod que matchea los parámetros reales de la operación. Nada de z.any() para evadir tipado. Paginación cursor correcta.
  3. Errores. Un status no-2xx del backend llega al cliente como error MCP con mensaje útil; no se traga ni se devuelve null silencioso.
  4. 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-Id solo si está configurado. Sin secretos hardcodeados.
  5. Escritura. Tools que mutan (POST/PATCH/DELETE) declaran sus efectos en la description y apuntan a operaciones realmente implementadas (no 501).
  6. Arranque. Falta de FT_API_KEY falla rápido y claro (exit), no a mitad de un tool.

Reglas

  • pnpm typecheck debe pasar; corrélo.
  • Reportá por severidad con file:line y 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.
Changes

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.
