Reference Model Context Protocol (MCP) server for K-product cross-border commerce — five canonical tools that every agent-ready storefront should expose.

#	Tool	Purpose
1	search_product	Keyword / category / price / locale search across the K-product catalog
2	get_product	Fetch a single SKU's full detail (i18n title/description, HS code, ship-from, lead time)
3	create_cart	Build cart with destination — returns itemized quote (subtotal + shipping + duty + import tax)
4	quote_checkout	Re-quote cart immediately before checkout (refresh FX/duty), returns canonical CartMandate VC
5	submit_intent	Submit AP2 IntentMandate VC + signed CartMandate, returns checkout URL + signed PaymentMandate

Canonical 5-tool surface per the Semore MCP commerce spec. Production Semore MCP server runs at https://mcp.semore.net. This OSS package ships schemas + reference handlers so merchants can validate integrations locally.

Install

npm install @semore/mcp-commerce zod

Use the published MCP server (Claude Desktop / ChatGPT / Gemini)

// Claude Desktop config — `claude_desktop_config.json`
{
  "mcpServers": {
    "semore": {
      "command": "npx",
      "args": ["-y", "@semore/mcp-commerce"]
    }
  }
}

Or discover via the official MCP Registry:

curl "https://registry.modelcontextprotocol.io/v0/servers?search=semore"
# → io.github.semorehq/[email protected]

Usage — schema-only (validate integrations)

import { searchProductTool } from "@semore/mcp-commerce/tools/search-product";

const parsed = searchProductTool.inputSchema.parse({
  q: "sunscreen",
  lang: "en",
  category: "kbeauty",
  limit: 10,
});

const result = await searchProductTool.handler(parsed);

Usage — boot a minimal MCP server

import { createMcpServer } from "@semore/mcp-commerce";

const server = createMcpServer({
  // Wire your own catalog / cart / order resolvers here.
  // Default skeleton resolvers return deterministic fixtures useful for local tests.
});

// Then expose over your preferred transport (stdio, streamable-http, SSE).
