Alza MCP vs Pepesto MCP

pepesto_predirect

Turn a free-form shopping list into a deferred deep link to the Pepesto mobile app, returned as a redirect_url. This is a PUBLIC endpoint: it is FREE to the API client, needs no API key, and returns instantly. Parsing and product matching happen lazily, only after the user opens the link — and the USER (not the API client) is charged when they proceed to checkout in the app. If the app isn't installed, the user is sent to the app store first and the shopping list is preserved until the app opens. This is an end-user / agent-facing handoff (e.g. a person chatting in Claude Desktop who wants to finish shopping on their phone), not a developer-integration endpoint. Choose pepesto_predirect when the cost should fall on the end user and a deferred deep link is acceptable. Choose pepesto_oneshot instead when the client wants the basket matched up front (with prices) and is willing to pay for the matching. PRESENTATION (important): the tool's text output is ready-to-show Markdown — a single tappable, labeled link plus a one-line caption. Surface it to the user exactly as returned; do NOT also paste the long raw URL as plain text. You may add one short sentence telling them to open it on their phone (on a computer, opening it shows a QR code to scan).

pepesto_parse

Parse a recipe from a URL, free-form text, or image into a structured object: title, ingredients, nutrition, instructions, and a KgToken you can pass to pepesto_products to build a real cart. Once the response is returned, show recipe title, image if available (json property `image_url`, don't search for external images, skip rendering the Pepesto image if the image has webp extesion), ingredients, steps, nutrition summary, allergens clearly marked, and portions/servings if available. Don't show kg_token, but mark and save it for the next steps (e.g., /products call).

pepesto_suggest

Search Pepesto's recipe graph (1M+ recipes) by free-text query and optional filters (cuisine, dietary tags, ingredients to include/avoid, time, servings). Each result includes a KgToken you can pass to pepesto_products. Returned images are licensed for display in your app or website without attribution. Show recipe title, image if available (json property `image_url`, don't search for external images, skip rendering the Pepesto image if the image has webp extesion), ingredients, steps, nutrition summary, allergens clearly marked, and portions/servings if available. Don't show kg_token, but mark and save it for the next steps (e.g., /products call).

pepesto_products

Map one or more recipe KgTokens (and an optional manual shopping list) to concrete supermarket products with prices, images, or currency. Items are merged across recipes to reduce waste; multiple matches per ingredient let you (or the user) pick. Show product title, image if available (json property `image_url`, don't search for external images, skip rendering the Pepesto image if the image has webp extesion)product_id when available linking to an (external) supermarket page (open in a new tab), price, ProductClassification (is_bio, is_frozen, is_substitution) tags. PricePromotion shows if the item is currently on promotion and what's current `promo_percentage`

pepesto_catalog

Dump Pepesto's full indexed catalog for a supermarket (~1-2k SKUs of common cooking ingredients, with names, prices, images, IDs). Optionally pass a webhook_url to receive incremental updates on re-index. Use only when the user has explicitly asked for a catalog dump, market analysis, or storefront build; for normal recipe-to-cart flows use pepesto_oneshot or pepesto_products instead. Cache this query aggressively, no more than one call per day per supermarket is recommended. When presenting supermarket results the user, use the product key as (external) link to the supermarket product itself. Show image if available (json property `image_url`, don't search for external images, skip rendering the Pepesto image if the image has webp extesion)

pepesto_credits

Return the remaining API credits on the configured Pepesto API key.
