Changes things 1Claude Code: ask
  • verifyCheck a claim or product query against the store.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    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.

    Annotations the server declares

    • destructiveHint: false
    • idempotentHint: true
    • readOnlyHint: true

  • get_requirementGet cited market-entry requirements for a product subject in a given market (e.g.No findings

    Why it is in this group

    • The name "get_requirement" says "get": a word for reading.
    Description, as the server wrote it
    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.

    Annotations the server declares

    • destructiveHint: false
    • idempotentHint: true
    • readOnlyHint: true
    • title: Get requirement
  • list_changesList recall and requirement changes since an ISO-8601 timestamp (e.g.No findings

    Why it is in this group

    • The name "list_changes" says "list": a word for reading.
    Description, as the server wrote it
    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.

    Annotations the server declares

    • destructiveHint: false
    • idempotentHint: true
    • readOnlyHint: true
    • title: List changes
  • search_recallsSearch official US recall records by product name, brand, model, or UPC.No findings

    Why it is in this group

    • The name "search_recalls" says "search": a word for reading.
    Description, as the server wrote it
    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.

    Annotations the server declares

    • destructiveHint: false
    • idempotentHint: true
    • readOnlyHint: true

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
