Pepesto Server

MCP server for the Pepesto API — give your agent the ability to turn any recipe (a URL, plain text, or a photo) into a matched basket of real supermarket products with live prices, across 26 European supermarkets. The MCP covers the recipe → matched cart half of the workflow (parse / search / map ingredients to SKUs / check catalogs); placing the actual order is a separate step — see Where checkout actually happens.

The MCP stops at "matched cart with prices" — see Where checkout actually happens for how users finish the order. /session, /checkout, and /link are intentionally not wrapped; see Roadmap for what's planned.

Example conversations

Quick: recipe URL → matched cart

The fastest path. One tool call returns a matched cart and a checkout link.

User: Use the BBC Good Food pizza margherita recipe to build a Tesco cart, and also add sparkling water and olive oil.

Assistant: [Uses pepesto_oneshot with content_urls, content_text, supermarket_domain: "tesco.com"]

Assistant: Cart matched at Tesco. Checkout link: <redirect_url>.

Browse the recipe graph → pick → matched cart

For "find me something to cook" prompts, where the agent searches Pepesto's recipe graph first and returns matched products with prices.

User: Find me a vegan pasta recipe for two.

Assistant: [Uses pepesto_suggest with query: "vegan pasta dinner for two"]

Assistant: Three options: Creamy Cashew Penne, Lemon Garlic Spaghetti, Roasted Veg Rigatoni. Which would you like?

User: Go with the first one. Shop it at Coop (coop.ch).

Assistant: [Uses pepesto_products with the chosen recipe's kg_token and supermarket_domain: "coop.ch"]

Assistant: Matched 8 ingredients at Coop — cashews CHF 4.20, penne CHF 1.95, ... — total CHF 18.40.

Parse a specific recipe → matched cart

When the user already has a recipe URL or text in mind. The MCP returns the matched product list — what to do with it is up to you.

User: Parse this and break out the ingredients: https://www.bbcgoodfood.com/recipes/pizza-margherita-4-easy-steps

Assistant: [Uses pepesto_parse with recipe_url]

Assistant: Pizza Margherita in 4 easy steps — 8 ingredients: strong bread flour, fast-action yeast, ...

User: Now match those to Sainsbury's products.

Assistant: [Uses pepesto_products with the returned kg_token and supermarket_domain: "sainsburys.co.uk"]

Assistant: Matched 8 ingredients at Sainsbury's — total £6.40.

Weekly meal plan → one merged matched cart

Multiple kg_tokens through pepesto_products in a single call — Pepesto merges duplicated ingredients across recipes.

User: Plan 5 keto dinners for the week and match them at Delhaize.

Assistant: [Uses pepesto_suggest with query: "keto dinner low carb high protein", num_to_fetch: 5]

Assistant: Five dinners: Steak & Kale, Salmon Avocado Bowl, Zucchini Lasagna, Cauliflower Risotto, Chicken Caesar.

User: Build one shopping list that covers the whole week.

Assistant: [Uses pepesto_products with all five kg_tokens and supermarket_domain: "delhaize.be"]

Assistant: Combined match: 24 unique ingredients (some shared across recipes), estimated total €68.40 at Delhaize.

Compare prices across two supermarkets

Run the same recipe through pepesto_products for each market and compare totals.

User: Parse this Sunday lunch recipe.

Assistant: [Uses pepesto_parse]

Assistant: Got it: Italian Sunday Lunch, 12 ingredients.

User: Show me the cart at both Esselunga and Conad so I can compare.

Assistant: [Uses pepesto_products twice — supermarket_domain: "spesaonline.esselunga.it", then supermarket_domain: "spesaonline.conad.it"]

Assistant: Esselunga: €34.20. Conad: €31.50. Conad is €2.70 cheaper, mostly on pasta and tomatoes.

Catalog dump for market analysis

Only on explicit request, and cache aggressively — see Pricing & best practices below.

User: I'm building a price-comparison dashboard. Pull the full Plus NL catalog.

Assistant: Heads up — pepesto_catalog is the most expensive call here. I'll only run it once; you should cache the result for at least a day. Confirm?

User: Yes.

Assistant: [Uses pepesto_catalog with supermarket_domain: "plus.nl"]

Assistant: Catalog dumped: 1,847 SKUs across 23 categories.

Where checkout actually happens

This MCP stops at "matched cart with prices." It does not automate placing the order on the supermarket's website. Two ways to finish the trip:

• Pepesto app (recommended). Open the redirect_url returned by pepesto_oneshot in a browser, or hand the user the matched-product list from pepesto_products and tell them to recreate it in the Pepesto app — that's where the hosted checkout flow lives, including login, basket review, and (for some markets) payment.
• The supermarket's own site. The user can take the matched product list from pepesto_products and add the SKUs directly on tesco.com / coop.ch / etc. Slower, but no Pepesto account needed.

Pricing & best practices

Pepesto runs on simple pay-as-you-go credits — you only pay for what your agents actually use, and credits never expire, so a top-up is yours until you spend it. We also offer discounts for students and early-stage teams, so say hi if that sounds like you. Full per-call pricing and volume tiers live at https://www.pepesto.com/pricing/.

A few tips to get the most out of every credit:

• pepesto_credits is free — call it any time for a quick balance read-out.
• pepesto_oneshot, pepesto_parse, pepesto_suggest, and pepesto_products are the everyday calls (match a recipe, plan a week, compare baskets) and are priced for routine agent use.
• pepesto_catalog does a full SKU dump for a supermarket and is the heaviest call. It's the right tool for genuine market analysis or price-comparison dashboards — just cache the result for at least a day per supermarket. Not sure you need it? Tell us about your use case and we'll usually point you to a cheaper path.

Roadmap

Planned to follow:

• pepesto_session — wrap /session so an agent can build a Pepesto-side checkout session from selected SKUs.
• pepesto_checkout — wrap /checkout, the turn-by-turn browser-automation loop that drives the supermarket's own site (login, add-to-basket, prompt-for-CAPTCHA, etc.). This is the missing piece for fully autonomous shopping.
• Hosted-checkout handoff — surface the Pepesto-app deep link as a structured tool result (instead of free text), so MCP clients can render it as a button instead of a URL.

If any of these would unblock you, tell us — it'll move them up the queue.
