graphql-audit is an agent for Claude Code from H-mmer/pentest-agents. It costs 34 tokens per session (1,402 once invoked), scanned A, original, no licence file.

A security review agent for GraphQL APIs, a way for applications to request exactly the data they need from an API.

In plain words
What is it for?
Use it to test GraphQL endpoints for authorization bypasses, query complexity attacks, injection, introspection issues, and batching abuse.
Why use it?
It helps find weaknesses in how GraphQL handles permissions, complex queries, batching, introspection, and injected input.

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

graphql-audit scanned grade A with 1 finding 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 6d 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.

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.
