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

mp-review 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 12d 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

/mp-review

Audit the current project's Mercado Pago integration. Local security checks require no MCP connection. Official quality and homologation operations connect only when their MCP tools are about to be used.

Behaviour

  1. The MCP configuration is bundled with the plugin. Never copy .mcp.json into the project and never scan an installation cache.
  2. Hand control to the mp-review skill, passing $ARGUMENTS through. Do not check MCP status first.
  3. Connect only immediately before the skill calls an MCP tool. Scope security is fully local. Other scopes may run their local portions first and authenticate only when they reach quality_checklist, quality_evaluation, form_homologation, save_webhook, or notifications_history.

Scopes

$ARGUMENTS (optional) narrows the review:

  • security — credentials, HTTPS, HMAC, server-side verification, idempotency; no MCP connection.
  • webhooks — defers to mp-webhooks for receiver correctness.
  • checkout / qr / subscriptions / marketplace — product-scoped check.
  • quality — only the official quality_checklist items.
  • full (default) — everything: security floor + product checks + quality checklist.

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.
