  + live POST probe of the endpoint
name: The Naked Market Storefront MCP (Universal Commerce Protocol)
status: published
status_raw: live
transport: streamable-http
endpoint: https://www.thenakedmarket.com/api/ucp/mcp
discovery: https://www.thenakedmarket.com/.well-known/ucp
protocol:
  name: Universal Commerce Protocol (UCP) shopping service over MCP/JSON-RPC
  spec: https://ucp.dev/2026-04-08/specification/overview/
  schema: https://ucp.dev/2026-04-08/services/shopping/mcp.openrpc.json
  versions:
  - '2026-04-08'
  - '2026-01-23'
platform: Shopify (native UCP support; backing shop tomorrow-ranch.myshopify.com)
authentication: Requests must identify the calling agent via a UCP-Agent profile URI (meta.ucp-agent.profile
  / UCP-Agent header); an unauthenticated tools/list probe returns JSON-RPC error -32001 "UCP discovery
  failed" (invalid_profile_url), confirming the endpoint is live and enforcing agent identification. Checkout
  completion requires explicit buyer approval; payment is handled via Shop Pay / configured payment handlers,
  never by the agent.
rate_limits: Rate limited per IP; agents are instructed to back off on 429 responses.
