Andium Store UCP / MCP
The Universal Commerce Protocol shopping service on Andium's merchandise storefront, exposed as a Model Context Protocol endpoint over JSON-RPC 2.0. Thirteen tools cover catalog search and lookup, product detail, cart create/update/cancel, checkout create/update/complete/cancel and order read, each with a full JSON Schema 2020-12 input schema returned live from tools/list. Anonymous for reads; payment requires an explicit human approval step. The protocol implementation is Shopify's native UCP support, served from an Andium-controlled host.
