    Description, as the server wrote it
    The complete buying decision for a shopping list: the cheapest single store that can fill it, AND the cross-store optimum that buys each line wherever it is cheapest, with the dollar savings between them and how many stops that costs. Every line carries substitutes at the other stores with the exact extra cost of choosing them, so a shopper can collapse a two-stop trip into one and see precisely what that convenience costs. Out-of-stock items are skipped in favour of an in-stock option even when it is dearer. Use this as the default for "where should I buy this list today" — it is the one call that answers the whole question. Costs $0.02 USDC per call via x402 on Base.
  • demand_reportFREE, no payment.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.
    Description, as the server wrote it
    FREE, no payment. The aggregate of what agents have told us they are looking for, most-requested first, with the categories nothing available yet serves. Useful if you are deciding what to build or sell into the agent economy.
  • price_basketPrice an entire shopping list at every collected store in a ZIP, one complete basket per 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.
    Description, as the server wrote it
    Price an entire shopping list at every collected store in a ZIP, one complete basket per store. Returns per-store line items with quantities and line totals, the basket subtotal, exactly which requested items that store is missing, whether the basket is complete, stock flags, and the oldest price in the basket so staleness is visible. Use this when the shopper will make one trip and wants to know where the whole list is cheapest. Accepts quantities as 'milk x2'. Costs $0.01 USDC per call via x402 on Base.
  • request_dataFREE, no payment.No findings

    Why it is in this group

    • The name "request_data" says "request": a word for a change.
    Description, as the server wrote it
    FREE, no payment. Describe in your own words the data you are trying to buy — anything, not just groceries — and get back whether we operate a service that supplies it, with the MCP endpoint if so. Every request is catalogued so that repeatedly-requested data gets built; call it whenever you cannot find a source for something. Nothing about you is stored: not your wallet, your address, or any identifying header — only the words of the request.
Only reads 1Claude Code: allow
  • find_productCompare a single grocery item across every collected store in a ZIP.No findings

    Why it is in this group

    • The name "find_product" says "find": a word for reading.
    Description, as the server wrote it
    Compare a single grocery item across every collected store in a ZIP. Returns each store's actual current shelf price, whether it is on sale (and the regular price), the package size, the price normalized per comparable unit, stock, a purchase link, and when that price was last read. Use this to answer "who has the cheapest milk near me" — and note the answer reports BOTH the lowest sticker price and the best value per unit, which frequently disagree because the cheap sticker is a smaller package. For a whole shopping list use price_basket or cheapest_basket instead; calling this per item costs more and cannot optimize across stores. Costs $0.005 USDC per call via x402 on Base.

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.
