description: PurelyB is a Shopify storefront that exposes a hosted, remote MCP server via the Universal
  Commerce Protocol (UCP, ucp.dev) for agent-driven commerce. The server implements the dev.ucp.shopping
  service (catalog search, cart, checkout, fulfillment). It is a standards server provisioned by Shopify,
  not a bespoke PurelyB build.

    tools.
