Lezzoo

Add one or more products to the cart in a single call (put a whole request's items in one call). For several of the SAME item use `quantity` (e.g. "2 Chili Boxes" → quantity: 2). For DIFFERENT products use `items` (an array of { productId, quantity?, optionValueIds? }), each with its own `quantity`. For a single product, pass `productId`/`quantity`/`optionValueIds` directly. product_id comes from search_merchant_products/get_product_details; optionValueIds are addon/size value ids from the product's options. One merchant per cart.

Return whether the customer is signed in for this session, and who.

Remove all items from the cart.

Return the signed-in customer's saved delivery addresses (title, details, type, coordinates). Requires the customer to be signed in for this session. Read-only.

Fetch the entire menu of a merchant in one call — all categories and all items. Use this when the user wants to browse the full menu, or when you need to find an item across all sections without paging. Returns every category with its products. Capped at 250 items total; if truncated, use search_merchant_products with query= to find specific items.

Return the signed-in customer's orders — `current` (in-progress) and `history` (past), each with merchant, status, total, item count and date. Requires the customer to be signed in for this session. Read-only.

Generate a payment link for a placed order. Use this if the payment link expired or was not returned at order placement. Requires sign-in.

List the available DIGITAL payment methods for checkout (e.g. Lezzoo Pay wallet, FIB, Card, Asia Pay, FastPay, Qi Card, NassWallet). Cash on delivery is NOT supported. Requires sign-in. Use this to map a payment method the user names to its payment_type_id.

Show full details for a single product/menu item by product_id (obtain it from a `search_merchant_products` result). Returns the image, description, price/discount, stock, and addon options (sizes, extras, toppings) with their prices — rendered as a card when the host supports MCP Apps. Call this when the user taps a product or asks about a specific item.

Return the signed-in customer's profile (name, phone, email, language, loyalty tier, total orders, member-since). Requires the customer to be signed in for this session. Read-only.

Return the platform's currently trending / most-searched terms. Useful for suggesting what users can look for. Takes no arguments.

Get the current Lezzoo Pay (wallet) balance for the signed-in customer. Requires sign-in.

Sign the customer out of this session (clears the stored token).

Place the order from the current cart. Call review_order first so the customer can confirm the total. Set confirm:true to actually place the order — without it, this returns a preview only. Requires sign-in and a non-empty cart.

Remove a cart line by line_id (from view_cart).

Prices the current cart for checkout (delivery, discount, fees, total) and renders an interactive widget in which the user selects their delivery address and payment method as tappable options — those details are chosen in the widget rather than in chat. Use when the user is ready to check out. Requires sign-in and a non-empty cart. Places no order.

Search Lezzoo for restaurants/stores near a location. Results are ranked by relevance and proximity, so location matters: pass the user's latitude/longitude when known. If location is unknown, the user's area/address can be used to derive it; otherwise a configured default location applies. Returns restaurants as cards (when the host supports MCP Apps). Use a returned merchant's `merchant_id` with `search_merchant_products` to open its menu. Anonymous — no sign-in or account is required. Read-only.

Show the menu for a merchant/restaurant by merchant_id (from a `search` result). The result includes the menu's `categories` (sections); pass a `categoryId` to browse that section's items (paged via `page`, with `has_more`). Omit both to show the top items; provide `query` to search within the menu. Renders as cards with category tabs and Prev/Next when the host supports MCP Apps. Results are paginated — a single response is only part of the menu. To locate a specific item, call this with `query="<item name>"`, which searches the entire menu across pages and sections (more reliable than paging for finding a named item).

Track a Lezzoo order live — status, ETA, driver name/status/location, merchant, destination, and the ordered items (name, description, quantity, price, chosen options, image) — rendered as a status card with a progress stepper (and a map when the driver's live position is available). Pass an order_id, or omit it to track the customer's most recent active order. Requires sign-in. Read-only. Call again to refresh.

Set the quantity of a cart line by line_id (from view_cart). Quantity 0 removes it.

Show the current shopping cart (items, options, quantities, line prices, subtotal). Anonymous — no sign-in required. Read-only.
