Agentic commerce has arrived
Build unified agentic experiences that securely act on behalf of buyers with the Universal Commerce Protocol (UCP) and Shopify's UCP-compliant MCP servers.
#### Start buildingAuthenticate, search the Catalog, build a cart, refer buyers to checkout, and monitor orders.
Anchor to How Shopify does UCPHow Shopify does UCP
Shopify's MCP tools implement UCP at every step of the buyer journey:
- Negotiate and authenticate: Identify your agent and get the right access tier.
- Discover products: Search across hundreds of millions of Shopify listings.
- Carts and checkout: Build carts, convert them to checkouts, and hand off to the merchant for payment.
- Monitor orders: Receive order webhooks and fetch fresh order state on demand.

Negotiate and authenticate
Define a profile so Shopify can verify your agent and apply the right rate limits and tool access. Higher trust tiers unlock broader access, including direct checkout completion. Profiles are hosted at a well-known URL and referenced on every UCP request.


Discover products
Query products across all Shopify merchants with the Global Catalog, or scope results to a single merchant with a Storefront Catalog. When buyers pick a product, fetch the variant details you need to build a cart or hand off to a checkout permalink.
Carts and checkout
Build carts as buyers iterate. Add line items, apply localization, and estimate totals across multiple turns of conversation. When buyers are ready, convert the cart into a checkout and refer them to the merchant storefront to complete payment. Trusted agents can complete checkouts directly.


Monitor orders
After checkout, monitor order lifecycle changes (fulfillment events, refunds, returns, exchanges, and cancellations) with UCP-shaped order webhooks. Fetch fresh order state on demand with the get_order MCP tool when the buyer asks "Where's my order?" or when reconciling a missed webhook.
