What is mcp-hub AGENTS.md?

Repository instructions for an MCP hub, a project that connects multiple AI-tool servers. They define rules for secrets, retries, logging, environment variables, and required checks.

Read them before modifying the hub, then run its type checks, linting, formatting check, and tests.

They reduce the risk of committing credentials, exposing sensitive arguments in logs, or retrying operations that change data.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00204	$0.00204
Opus 5.5	$0.00082	$0.00082
Sonnet 5.5	$0.00041	$0.00041
Haiku 4.5	$0.00020	$0.00020

Security

Grade A, and why

mcp-hub 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 2mo 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

AGENTS.md -- mcp-hub

As regras operacionais deste repo sao canonicas em CLAUDE.md (fonte unica para Claude/Codex/Hermes). Leia-o antes de tocar em codigo.

TL;DR das invariantes:

hub-config.json nunca entra no git -- contem paths e env-refs de maquina
.env, tokens, auth-state e credenciais nunca commitados -- rodar gitleaks antes de push
toolCallRetries somente em tools explicitamente idempotentes -- em mutating tools e falha de seguranca
src/utils/redaction.ts e o ponto central de sanitizacao; nao logar args brutos em outros modulos
Downstream stdio servers: variaveis extras via inheritEnv, nao passando process.env inteiro

Validar: npm run type-check && npm run lint && npm run format:check && npm test

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.
