name: Oatside SG Storefront UCP/MCP Server
status: live
ownership_note: >-
  The MCP server is provided by the Shopify platform (Universal Commerce Protocol native
  support) and is scoped to Oatside's own merchant tenant — the UCP profile names merchant
  "Oatside SG", merchant_origin shop.oatside.com and shop_id 57430966333, and the tools
  operate on Oatside's catalog, carts and orders. Oatside did not author the protocol or
  the server implementation; it enabled it on a host it controls. Recorded as Oatside's
  agent surface, not as Oatside-authored engineering.

notes:
- Every tool inputSchema requires meta.ucp-agent.profile — a URI identifying the calling
  agent. tools/list is anonymous, but tools/call without a resolvable agent profile returns
  JSON-RPC error -32001 / invalid_profile_url.
- Prices are integers in ISO 4217 minor units paired with a currency code.
- The provider's own agents.md forbids unattended payment completion; complete_checkout
  requires contemporaneous human buyer approval.
