Connect a UCP client

Open Connect in the embedded Shopify app and copy the endpoint shown for that store. The endpoint belongs to the merchant's Shopify storefront; Tilda is not a commerce-data relay.

https://<merchant-store>.myshopify.com/api/ucp/mcp

Provider-neutral configuration

Use the endpoint in a UCP-compatible client controlled by the reviewer or shopper. A generic MCP-style configuration has this shape:

{
  "mcpServers": {
    "shopify-store": {
      "url": "https://<merchant-store>.myshopify.com/api/ucp/mcp"
    }
  }
}
