KnownGate does not always answer

Over the last week it answered 91.4% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Available tools 4

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

item
check_item
Rule one food subject against the household premise (restrictions, thresholds, or both). Needs a key (Authorization: Bearer kg_live_…); create a free one with the register tool. Returns one of four verdicts (no_conflict_found, conflict_found, ask_one_question, couldnt_verify) with typed hits, source kind and read date. Unknown counts as no; the word safe is never used.
plan
check_plan
Rule a set of items at once: a recipe's ingredients, a basket, several days. Needs a key (Authorization: Bearer kg_live_…); create a free one with the register tool. Up to 25 subjects, one call, one verdict per item plus a summary line. Each item carries its own evidence, source and read date.
register
register
Sign yourself up for a developer key without leaving MCP. The email is contact and recovery, not a wall. One key per email, free tier (100 checks a month); the key is in this response and never shown again. Nothing on knowngate.com itself needs a key.
venue
check_venue
Rule a whole venue's published chart against the household restrictions in one call. Needs a key (Authorization: Bearer kg_live_…); create a free one with the register tool. Returns per-verdict counts, the most severe items, the operator's cross-contact caveat verbatim, and the chart's source and read date. A venue with no machine-readable chart says so honestly.

KnownGate — questions

Answers built from our own checks of this server.

What can KnownGate do?
It exposes 4 tools, read directly from the server on our last check. Among them: check_item, check_plan, check_venue, register. 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 KnownGate working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 48 of 93 checks got a reply (51.6%), average response time 507 ms. The bar chart above shows every period we have measured.
How do I connect KnownGate?
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 KnownGate need an API key?
No. KnownGate completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is KnownGate?
It answers our handshake in 507 ms on average, which is faster than 31% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is KnownGate 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.
