AI Guardrails — questions

Answers built from our own checks of this server.

What can AI Guardrails do?
It exposes 5 tools, read directly from the server on our last check. Among them: check_hallucination, check_safety, detect_pii, full_check, redact_pii. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is AI Guardrails working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 160 ms. The bar chart above shows every period we have measured.
How do I connect AI Guardrails?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does AI Guardrails need an API key?
No. AI Guardrails completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is AI Guardrails?
It answers our handshake in 160 ms on average, which is faster than 72% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is AI Guardrails open source?
Yes — written in JavaScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
