🟢search(query)
Use this when you need citable sources for a free-text question about what is on offer in Italian store flyers (volantini) right now, and no filters or sorting are needed. Covers Italy only. Takes one query in Italian that may name a product, a chain and a city ("caffè Lavazza a Milano", "volantino Lidl", "prezzo pasta"). Returns matching documents — current offers, store flyers and weekly product price pages — each with an id, a title stating price, chain and validity, and its URL on prezzinvista.it. The full text of a document is what fetch returns for its id. Sorting by price, a price cap and a choice of chains belong to search_flyer_offers.

}🟢fetch(id)
Use this to read one of the documents returned by search, given its id. Returns the full text and the URL to cite. For an offer: price, previous price, pack size, price per kg or litre, chain, validity, and the same product in the other chains' current flyers. For a flyer: validity, number of offers and biggest discounts. For a product: this week's typical and lowest flyer price, the trend and each chain. Ids come only from search. Covers Italy only.

}🟢search_flyer_offers(query, city, sort, discounted_only, stores, ...)
Use this when the user wants to know where a product is on offer in Italy this week, at what price, at which chain and until when, and you need filters or sorting: a city, specific chains, a price cap, lowest price or lowest price per kg first. Searches the offers currently valid in the flyers (volantini) of Italian supermarkets, discount stores and electronics chains. Product names are in Italian: pass Italian words in `query` ("caffè", "pasta barilla", "lavatrice"). Returns price, previous price, pack size, price per kg or litre, department, chain, expiry date and the link to the offer on prezzinvista.it. Covers Italy only: not for other countries, not for online-shop prices. Flyer prices are indicative; the price displayed in store prevails. In hosts that support MCP Apps the results are also shown to the user as cards with photo, price and link.

}🟢list_current_flyers(city, store, limit)
Use this when the user asks which store flyers (volantini) are valid right now in Italy, whether a chain has a flyer this week, or until when a flyer is valid, optionally only for chains with a store near a city. Returns chain, validity dates, number of offers, distance of the nearest store and the link to the flyer on prezzinvista.it. Covers Italy only. Products inside the flyers are what search_flyer_offers looks up. In hosts that support MCP Apps the results are also shown to the user as cards with logo, validity and link.

}🟢get_price_trend(product)
Use this when the user asks how much a common grocery or household product costs in Italy this week, whether it is getting cheaper or more expensive, or which chain has it cheapest: e.g. "how much does pasta cost this week", "is coffee more expensive than last week". Returns the typical (median) and lowest flyer price this week, the previous weeks and each chain this week, with the link to the product page on prezzinvista.it. Covers Italy only, and about two hundred staple products (pasta, caffè, olio di oliva, latte, detersivo, pannolini, …), named in Italian; specific brands and models are what search_flyer_offers looks up. In hosts that support MCP Apps the results are also shown to the user as a card with the weekly trend.
