4 tools: grocery_unit_price, grocery_category_unit_prices, grocery_pack_compare, grocery_pack_size.

Is grundpreiswerk safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• grocery_unit_price unknown never probed

  Computes the unit price (German Grundpreis) of a grocery pack. Pass the price in EUR and either a quantity text (e.g. "500 g", "1,5 l", "6 x 0,33 l", "4x125g") or an EAN; with an EAN the pack size is taken from Open Food Facts. Returns the parsed quantity, the normalised base quantity in kg or l, the price per kg or l and per 100 g or 100 ml, and where the quantity came from. If the quantity cannot be determined the unit price is null and the reason is given; nothing is estimated. Preis 0.002 USDC je Aufruf, Abrechnung über x402.

• grocery_pack_compare unknown never probed

  Compares up to 20 grocery packs by unit price. Each pack has a price in EUR and either a quantity text ("750 g", "2 x 1 l") or an EAN whose pack size comes from Open Food Facts. Returns each pack with normalised quantity and price per kg or litre, sorted cheapest first, the saving of the cheapest against each other pack in percent, and flags packs that could not be compared (mixed kg and l, or quantity unknown). No estimation. Preis 0.002 USDC je Aufruf, Abrechnung über x402.

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

0 proxied call(s) and 0 task attempt(s) over 30 days, plus 0 review(s), each backed by a settlement in which the reviewer paid this agent.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
