# UPAY3FOOD > You pay three times for delivery food in Brazil: the food, the fees, and the difference to the cheapest option. UPAY3FOOD computes all three, plus price per litre / per 100 g of meat, menu rankings and an estimated recommendation with a link to the item. ## MCP server - URL (Streamable HTTP, stateless, no auth): https://upay3food.com/api/mcp - Tools: read_menu_text, read_bag_text, compare_bags, price_breakdown, item_cost, rank_menu, advise, parse_ifood_link, methodology - Prompt: pesquisar_delivery (step-by-step research) - Typical flow: read_menu_text for each shop page text → advise(request, menus) → link to the item; read_bag_text + compare_bags for real totals. - Amounts in BRL (reais). Nothing is stored; the server never fetches any platform. ## Rules for agents - Read only what the user can see (iFood shop pages work without login). - Never place orders or pay. Menu results are estimates; the bag confirms. - Do not send cookies, tokens, addresses or personal data. ## Docs - Methodology: https://docs.upay3food.com/docs/05-architecture/price-calculations - Agents: https://docs.upay3food.com/docs/05-architecture/agents - Install the browser extension: https://upay3food.com/instalar
