Cosimo

Display product images and cards after product_search/product_lookup. Presentation only: this does not create a cart, reserve inventory, initiate checkout, place an order or process payment. Do not call solely to fulfill requests to purchase, track/refund orders, or edit merchant prices or inventory. A purchase request alone is not a request to display products. Use this when showing product images for a supported product-information request in an MCP Apps host, including a single product or a follow-up detail reply, not only a shortlist. Pass 1..12 merchant product URLs in recommendation order, optionally with a short reason and a verified variant SKU from product_lookup. Product facts are resolved through Cosimo's authenticated, quota-limited indexed lookup; this does not run another search or fetch merchant websites. UI-capable MCP Apps hosts display Cosimo cards and optimized product images. Other hosts receive readable product links, prices and honest stock descriptions.

render_products

Look up one product by its product-page URL on any supported merchant site (for example https://www.lagence.com/products/...). Returns the product's details, prices, images, sizes, colors, variants, and a Markdown rendering suited to summarising the product. The URL must be an absolute http(s) link to a single product page, not a category, search, or home page. If the product is not in Cosimo's index yet, this returns an error and product_search may still find it by description. Use for explicit product-information requests, including variant availability and retailer links. Looking up a variant does not reserve stock or start checkout. Do not use solely to fulfill requests to place orders, process payments, track/refund orders, or edit merchant prices or inventory. To include images in a single-product or follow-up detail reply in an MCP Apps host, call render_products with this product's returned merchant productUrl. Keep the verified material, size, color, price, and stock details in the chat response alongside the card.

Search Cosimo's cross-merchant product catalog with a natural-language query such as 'black midi dress under $200' or 'waterproof trail running shoes'. Returns up to 20 products with title, brand, currentPrice, description, materials, currency, stock, colors, sizes, images, a Cosimo product page URL, and the merchant's own URL. Use this for discovery and comparison; use product_lookup for one known URL. Do not use solely to fulfill requests to place orders, process payments, track/refund orders, or edit merchant prices or inventory. A purchase request alone is not a product-discovery request. To show selected products with images for a supported request in an MCP Apps host, call render_products with their returned merchant productUrl values.
