HallucC — Hallucination & Safety Guardian — questions

Answers built from our own checks of this server.

Why is there no tool list for HallucC — Hallucination & Safety Guardian?
The server answered our handshake with an authorization challenge, so it is running — but it will not describe its tools to an anonymous client. To see them you need to connect with your own credentials. We record it as alive, not as broken: 100.0% of checks in the last 24 hours got a reply.
Is HallucC — Hallucination & Safety Guardian working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 1153 ms. The bar chart above shows every period we have measured.
How do I connect HallucC — Hallucination & Safety Guardian?
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. You will need your own credentials: it refuses anonymous clients.
Does HallucC — Hallucination & Safety Guardian need an API key?
Yes. Every time we knock, HallucC — Hallucination & Safety Guardian answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.
How fast is HallucC — Hallucination & Safety Guardian?
It answers our handshake in 1153 ms on average, which is faster than 6% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is HallucC — Hallucination & Safety Guardian open source?
Yes — it is published under the MIT licence, written in TypeScript 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.
