description: >-
  SUPER73's North American storefront exposes a hosted, remote MCP server implementing the Universal
  Commerce Protocol (UCP) shopping service. tools/list answers anonymously over plain JSON-RPC with 13
  tools, each carrying a complete JSON Schema inputSchema. The server is discovered from
  https://super73.com/llms.txt and https://super73.com/agents.md, and declared in the UCP merchant
  profile at https://super73.com/.well-known/ucp.
ownership: >-
  The UCP profile resolves the store to lithiumcycles.myshopify.com — SUPER73 launched in 2016 under the
  Lithium Cycles banner, and that is still the Shopify store handle. The profile's Google Pay handler
  names merchant_name "SUPER73" and merchant_origin "super73.com", confirming the endpoint belongs to
  this company.
deployment:
  mode: remote
  endpoint: https://super73.com/api/ucp/mcp
  auth: none
  verified: probed
  note: >-
    Anonymous tools/list succeeds with no credential. Buyer-scoped operations (customer identity, saved
    payment methods) escalate to the Shopify customer-account OAuth server declared in
    /.well-known/oauth-authorization-server; the catalog and cart tools are reachable without one.
    Payment completion additionally requires contemporaneous human buyer approval per the store's own
    agent instructions. No stdio/npx package is published — this is a URL an MCP client POSTs to.

conventions:
  money: >-
    Prices are integers in the currency's ISO 4217 minor units paired with a currency code —
    {"amount": 2500, "currency": "USD"} is $25.00. Agents must convert to major units before quoting.
  ids: Shopify global IDs, e.g. gid://shopify/Checkout/abc123
  agent_profile: >-
    Every tool requires meta.ucp-agent.profile — a URI identifying the calling agent, used for UCP agent
    profile discovery.
  buyer_context: Pass context.address_country and context.currency for accurate pricing and availability.
