Nothing serious here today

Today is the operative word: we check Bies Guardian every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

claim

claim_safety_verdict

Deterministic, sealed pre-publication verdict on a PUBLIC claim (marketing copy, product page, ad headline). Returns per-claim verdict (PASS / CONDITIONAL_PASS / STOP), severity, and a reproducible replay_hash. A 0-LLM rules engine grounded in KR 표시광고법 / US FTC claim categories — NOT legal advice, NOT market proof or launch approval. Call this before a public claim ships.

idea

idea_rehearsal

Deterministic decision-rehearsal verdict on a founder's BUSINESS IDEA (not a public claim). Returns a graded verdict (Conditional GO / Clear one critical gate / Confirm the headwind / Verify the basics / Redesign the structure / Firm up the inputs / Hold·Redesign) driven by the venture's structural signals, with a reproducible seal. Classification is retrieval-grounded; the verdict and seal are reproducible. NOT market proof, NOT investment advice. Use to pressure-test an idea before committing.

rejudge

rejudge_claims

Re-judge a prior claim-safety verdict against new EVIDENCE. Pass the 'artifact' returned by claim_safety_verdict plus 'observations' (what happened). The top-level verdict NEVER changes on evidence (conservative by design); what moves is 4 axes — now-sayable lines (behind your owner-gate), permanently issuer-only claims, claims still short on evidence, and new risks. Deterministic, sealed, stateless (nothing stored).

Bies Guardian — questions

Answers built from our own checks of this server.

What can Bies Guardian do?

It exposes 3 tools, read directly from the server on our last check. Among them: claim_safety_verdict, idea_rehearsal, rejudge_claims. 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 Bies Guardian 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 513 ms. The bar chart above shows every period we have measured.

How do I connect Bies 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.

Does Bies Guardian need an API key?

No. Bies Guardian completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Bies Guardian?

It answers our handshake in 513 ms on average, which is faster than 30% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
