MCP App Store

Overview

Skuup lets you name your price for a specific product and takes that price to the stores that carry it. Paste a product link and the price you will pay; Skuup finds legitimate sellers of that exact item, asks each one once, and brings back their answers: yes, a counter, or no. When a store accepts, you get a link to the offer's own page on Skuup, where you pay the store directly. Nothing is bought until you do. In ChatGPT you can read a product page as Skuup sees it, find stores that carry an item, make an offer, check your offers, answer a counter, change how long you will wait, or withdraw an offer. ChatGPT confirms the item, the price, the quantity and where it ships before any offer goes out and before any answer to a store. Your Skuup account is the same one the Skuup extension and the iPhone app use, so your offers appear everywhere. Skuup is a service for new goods from real stores, shipped to US addresses. It never takes your card details in the conversation, never shows you another shopper's offers, and never reveals a store's private pricing.

Tools

buy_now

ChatGPT
Buy the item at its exact list price from a store that has the Skuup app, accepted on the spot with a payment link. Only works for those stores; otherwise it answers that no app store carries it and make_offer is the way. Confirm with the shopper first: this creates an order the shopper then pays.

cancel_offer

ChatGPT
Withdraw an open offer. No store is emailed about it; a store that opens its link afterwards sees the offer is closed. An accepted offer cannot be withdrawn. Confirm with the shopper first.

get_offer

ChatGPT
One offer's current status, the store's answer, its page on Skuup's domain and the payment link when accepted.

list_offers

ChatGPT
The shopper's offers, newest first, with status.

make_offer

ChatGPT
Name the price the shopper will pay for an exact item. Skuup then asks the stores that carry it; each can accept, counter or decline, and an acceptance returns a payment link. This asks real stores, so confirm the item, the price, the quantity and the ship-to ZIP with the shopper first. Give product_url (Skuup reads the page) or the product details from read_product_page. A price at or above the store's list price is not sent: the tool answers with the list price so the shopper can buy at it or offer less.

read_product_page

ChatGPT
Read a store's product page and return the product as Skuup sees it: title, brand, barcode when the page carries one, list price, currency, availability. No offer is made. Use it before make_offer so the shopper can confirm the exact item and variant. The product fields follow Skuup's product schema (https://ext.skuup.co/connector).

respond_to_counter

ChatGPT
Answer a store's counteroffer. Accepting returns the payment link. Confirm the counter price with the shopper first.

search_products

ChatGPT
Find stores that carry an item, by name, with each store's price and availability right now. Searches one live cross-store catalog (Shopify's Global Catalog, millions of stores but not every store), results are not kept, up to 10 listings. The offer itself goes to every store Skuup finds, in this catalog or not. Use read_product_page on a result's URL before making an offer.

set_offer_wait

ChatGPT
Set how many more days the shopper will wait for store answers: 7, 14 or 30, or null for until withdrawn. Only for offers Skuup takes to stores by email (not a buy now or an app store order).
