KnownGate is the food verification layer for people and AI agents: it checks food against what must not be in it, or a number it must stay under, and returns evidence-backed verdicts with their sources and read dates.
Official registry entry: com.knowngate/verify. Transport: Streamable HTTP at https://mcp.knowngate.com.
Tools: check_item, check_venue, check_plan, register. Four verdicts (no_conflict_found, conflict_found, ask_one_question, couldnt_verify); two are honest ways of saying we don't know; the word safe never appears. A free key (100 checks a month) is created in-band with the register tool, no signup. Evidence standard: https://www.knowngate.com/standard
Server tool list (4)
Raw names from tools/list. Only developers need these.
| 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. |
| 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. |
| 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 | 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. |
