For shoppers

Use ShopItUp in Claude or ChatGPT

Ask your AI assistant to find new and previously loved clothing across every store on ShopItUp, compare items, and price an order with live shipping and tax. When you decide to buy, it gives you a link to ShopItUp's own checkout — you review the order and pay there. Your assistant never sees your payment details.

Where to connect

Shop without signing in

Search, item and store details, prices with shipping and tax, and checkout links.

In ChatGPT

Everything, with sign-in only when you need it: shop right away, and ChatGPT asks you to sign in when you ask about your sizes, address or orders.

Set it up

In Claude

Open ShopItUp in Claude's connector directory and connect it — or add it yourself: open Customize → Connectors and choose Add custom connector.
Adding it yourself? Paste https://shopitup.ca/mcp or https://shopitup.ca/mcp/account and add it.
For /mcp/account, Claude opens ShopItUp's sign-in page: sign in (or create a free account and confirm your email), review what Claude may see, and choose Allow Claude.

In ChatGPT

Open ShopItUp in ChatGPT's apps — or search for ShopItUp in ChatGPT's apps — and connect it.
Shop right away: searching, prices and checkout links need no account.
When you ask about your sizes, your saved address or your orders, ChatGPT opens ShopItUp's own page: sign in and choose Allow ChatGPT.

In other assistants

Add ShopItUp as a connector with /mcp or /mcp/account. With /mcp/account, you sign in and approve on ShopItUp's own page in the same way.

You'll need: nothing to shop without signing in; a free ShopItUp account with a confirmed email address to connect your account.

Good to know

You always pay on ShopItUp. The assistant prepares a checkout link; nothing is bought until you open it and pay. A checkout link works for 30 minutes and reserves nothing, so someone else can still buy the item until you pay; you can ask the assistant to cancel it.
Every item is one of a kind. Availability is checked again when you price an order and when you pay.
Your own country's stores. shopitup.ca shows the stores in its own country, in its own currency.
What ShopItUp sees. Your searches and the items you ask about; with your account connected, only what you approved. ShopItUp never receives your conversation with the assistant. See the Privacy Policy, section 3.1.
Disconnect any time under Connected apps in your ShopItUp account settings — the assistant loses access at once.
