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

mcpgate AGENTS.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 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.

Repository Guidelines

Contexto

MCPGate es un monorepo con pnpm workspaces. La prioridad es mantener una estructura local funcional y con mínima fricción.

Package manager

  • Usar pnpm desde la raíz del monorepo.
  • No usar npm, yarn ni lockfiles nuevos por app.

Apps

  • apps/api: API NestJS, migrada desde mcpgate-api.
  • apps/cli: CLI Oclif, migrado desde mcpgate-cli.
  • apps/web: Web Next.js, migrada desde mcpgate-web.

Reglas de trabajo

  • Mantener y respetar los AGENTS.md locales dentro de cada app.
  • No crear packages/ compartidos hasta que exista una necesidad real.
  • Cambios cross-app deben ser explícitos y mínimos.
  • Ejecutar comandos filtrados con pnpm --filter <package-name> ... cuando se trabaje en una app específica.
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.
