## Tools (as reported by the server, not verified)

- `search\_substances`: Look up substances by name on one regulatory axis \(same as HTTP GET /v1/substances?name=…\). The name is normalised \(NFKC, whitespace removed, lower-cased\) and matched \*\*exactly\*\* against the names and aliases the axis itself uses in that language \(E numbers and official names for EU, 品目名 and label t
- `get\_substance`: One substance with everything its own roster says \(same as HTTP GET /v1/substances/\{id\}\): identifiers, category, aliases, translations, the source-ledger row, groups, and — depending on the axis — Japanese use standards, EU/Codex conditions of use, mandatory labelling statements, the roster's defini
- `analyze\_label`: Find the additives named on a label \(same as HTTP POST /v1/labels/analyze\). Splits the additive section into tokens and returns, per token, the substances it resolves to \(SubstanceSummary: facts on their own axis\), plus known interactions between the detected substances. Cutting the additive section

This tool does not return that data: it returns the
- `analyze\_label\_diff`: \(Paid; not available through MCP.\) Same input as analyze\_label, but each detected substance carries the cross-axis derivation. This tool does not return that data: it returns the HTTP endpoint \(POST /v1/labels/analyze/diff with the same JSON body, 0.01 USDC per request via x402 on Base\) to call inst
