status: live
description: >-
  Rael's storefront exposes a live, anonymous MCP server implementing the Universal Commerce
  Protocol (UCP) shopping service. An unauthenticated POST of {"jsonrpc":"2.0","id":1,
  "method":"tools/list"} returned HTTP 200 with 13 tools, each carrying a complete JSON Schema
  inputSchema — no OAuth challenge, no API key. The saved manifest in rael-mcp-tools.json is
  the verbatim response body.
ownership_note: >-
  The endpoint is served from Rael's own domain (www.getrael.com) and its catalog, cart and
  order tools operate on Rael's store only. The server software is Shopify's — Shopify ships
  UCP natively for every store, the /.well-known/ucp profile advertises the canonical form of
  the endpoint on the shop's myshopify alias (raelbox-com.myshopify.com/api/ucp/mcp), and the
  response carries powered-by: Shopify. This is the templated/platform-hosted case: the
  contract is real, live and scoped to Rael, but Rael did not author the tool schemas.
