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

mcphub 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 2d 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

MCPHub — Agent Guide

MCPHub (@samanhappy/mcphub) is a TypeScript/Node.js ESM hub that aggregates MCP servers behind a single HTTP service with a React/Vite dashboard.

Always apply

  • Use pnpm ([email protected], declared in package.json).
  • Treat the current implementation as the source of truth. If this guide disagrees with the code, follow the code and update the guide; tests document expected behavior and should change only when behavior intentionally changes.
  • Do not hand-edit generated output: dist/, frontend/dist/, or coverage/.
  • Read the scoped guide relevant to the files you will change. The full index is in docs/agents/README.md.

Project-specific build checks

  • Backend typecheck/build: pnpm backend:build
  • Full build: pnpm build
  • Distribution verification: node scripts/verify-dist.js

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.
