README

Silicon MCP

A Model Context Protocol server for the Silicon Product API — let Claude (or any MCP client) search products, compare prices, and look up product details across hundreds of stores.

This package is a thin client. All the work runs on Silicon's infrastructure; the only thing you need locally is an API key.

Tools

Tool	Description
`get_product`	Full product details (price, availability, GTIN/MPN, images, specs) from one product URL
`search_products`	Find a product across a region's enabled retailers
`compare_prices`	Per-retailer offers + low/high price range for one product
`list_retailers`	Supported retailers per region (free)

Get an API key

Sign up at https://siliconstore.com/developers — the free tier includes a monthly request allowance. Your key looks like sk_live_….

Install as a Claude plugin (one command)

/plugin marketplace add silicon-store/silicon-mcp
/plugin install silicon@silicon

Then set SILICON_API_KEY in your environment. The plugin bundles this MCP server and adds a /product <url> command.

Use with Claude Code (MCP only)

claude mcp add silicon --env SILICON_API_KEY=sk_live_your_key -- npx -y silicon-mcp

Use with Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "silicon": {
      "command": "npx",
      "args": ["-y", "silicon-mcp"],
      "env": { "SILICON_API_KEY": "sk_live_your_key" }
    }
  }
}

Environment variables

Var	Required	Default	Purpose
`SILICON_API_KEY`	yes (stdio)	—	Your `sk_live_…` key
`SILICON_API_BASE_URL`	no	`https://productapi.siliconstore.com`	Override the API host

Transports

stdio (default): npx silicon-mcp — for desktop/CLI MCP clients.
Streamable HTTP (hosted): node dist/http.js → POST /mcp. Multi-tenant — each request forwards the caller's own Authorization: Bearer sk_… to the API.

Develop

npm install
npm run build
SILICON_API_KEY=sk_live_… npm start
