About this server
Guardrails for LLM output: pass / fail / review verdicts with calibrated confidence in under 500 ms.
Local — runs on your machine over stdio (npx / uvx / docker / bundle). Indexed under Dev Tools, alongside 236 other servers. Health is freshness-derived from the registry's last-update timestamp; this index does not run the server, so capabilities and tool lists live in the source repository.
