Tools (4)

🟢 Read-only🟡 Write🔴 Delete⚪ Unknown
🟢search_recalls(query, market, limit)

Search official US recall records by product name, brand, model, or UPC. Covers CPSC consumer products and FDA food, drug and device enforcement. Returns only cited records from the store, each with a source URL and a match score. If nothing matches, returns an empty list rather than guessing.

Input Schema

{
  "type": "object",
  "properties": {
    "query": {
      "title": "Query",
      "type": "string"
    },
    "market": {
      "default": "US",
      "title": "Market",
      "type": "string"
    },
    "limit": {
      "default": 10,
      "title": "Limit",
      "type": "integer"
    }
  },
  "required": [
    "query"
  ],
  "title": "search_recallsArguments"
}
🟢get_requirement(subject, market)

Get cited market-entry requirements for a product subject in a given market (e.g. subject='childrens_products', market='US'). This is a small curated set, not a full regulatory database: CPC, CPSC eFiling, EU GPSR, CE marking, REACH SVHC, RoHS and California Prop 65. Returns each fact with its official citation URL and last-verified date.

Input Schema

{
  "type": "object",
  "properties": {
    "subject": {
      "title": "Subject",
      "type": "string"
    },
    "market": {
      "anyOf": [
        {
          "type": "string"
        },
        {
          "type": "null"
        }
      ],
      "default": null,
      "title": "Market"
    }
  },
  "required": [
    "subject"
  ],
  "title": "get_requirementArguments"
}
🟢list_changes(since, limit)

List recall and requirement changes since an ISO-8601 timestamp (e.g. '2026-09-01T00:00:00+00:00'). Includes newly published recalls and rule changes, each with its source URL.

Input Schema

{
  "type": "object",
  "properties": {
    "since": {
      "title": "Since",
      "type": "string"
    },
    "limit": {
      "default": 100,
      "title": "Limit",
      "type": "integer"
    }
  },
  "required": [
    "since"
  ],
  "title": "list_changesArguments"
}
🟢verify(query)

Check a claim or product query against the store. Returns only cited records (recalls and requirements) that match. Explicitly reports 'no verified record' when nothing matches -- it never synthesizes an answer, so absence means 'not in the store', not a negative claim.

Input Schema

{
  "type": "object",
  "properties": {
    "query": {
      "title": "Query",
      "type": "string"
    }
  },
  "required": [
    "query"
  ],
  "title": "verifyArguments"
}
