Bartesian Commerce (UCP Shopping)

name: Bartesian Commerce (UCP Shopping)
description: 'The agent-facing commerce surface of the Bartesian Shopify storefront. The store publishes
  a Universal Commerce Protocol merchant profile at https://bartesian.com/.well-known/ucp declaring UCP
  versions 2026-04-08 and 2026-01-23, the dev.ucp.shopping service over both an MCP transport at https://bartesian.com/api/ucp/mcp
  and an embedded transport, and eight capabilities covering cart, checkout, fulfillment, discount, order
  and catalog search/lookup. Unlike most UCP storefronts, this endpoint answers an anonymous initialize
  and tools/list with HTTP 200, returning all 13 tools together with their full JSON Schema draft 2020-12
  input schemas - the real contract, captured verbatim. Tool invocation is gated: every tool requires
  a meta.ucp-agent.profile URI, and an anonymous tools/call returns HTTP 422 with JSON-RPC error -32001.'
