description: >-
  Flying Embers serves a live, unauthenticated Model Context Protocol endpoint on its own
  domain as part of the Universal Commerce Protocol (UCP) shopping service. A tools/list
  call returns 13 real tools with full JSON Schema input contracts covering catalog search
  and lookup, cart lifecycle, checkout lifecycle, and order retrieval. The surface is
  provided by the Shopify commerce platform but is served from www.flyingembers.com,
  advertised by the merchant's own /llms.txt, /agents.md and /robots.txt, and the UCP
  merchant profile names this merchant explicitly (merchant_name "Flying Embers",
  merchant_origin www.flyingembers.com).

notes:
  - Every tool requires a meta.ucp-agent.profile URI (agent profile URI for UCP discovery).
  - complete_checkout additionally requires meta.idempotency-key (string).
  - Money is expressed as an integer in ISO 4217 minor units paired with a currency code.
  - The merchant's llms.txt and robots.txt both state that checkout/payment must not be
    completed without explicit, contemporaneous human approval.
  - Platform-provided surface. This is the Shopify UCP implementation, served on the
    merchant's own domain and scoped to the merchant's own catalog (shop id 35263676475).
