CartScout MCP server

Give Claude, Cursor or any MCP-capable AI agent live product prices, stock, variants and deal ratings from online stores. Paste a product link into the chat and ask "is this a good price?", "which of these three stores is cheapest and in stock?" or "does it come in size 10?".

Works with Shopify, WooCommerce, Walmart and eBay stores, with Amazon in beta. The data comes from the CartScout API, which handles fetching, bot filters and parsing. Try the API in your browser first, no sign-up needed.

Tools

ToolWhat the agent getsUses
get_productPrice, list price and discount, stock, variants (sizes, colours) with their own price and stock, SKU / GTIN, rating, optional reviews and description1 extraction
compare_products2-10 pages ranked: cheapest, cheapest in stock, best rated, biggest discount, price spread, same product by GTIN1 extraction per URL, PRO plan or higher
check_dealDeal rating of the current price against its recorded history, with average, lowest and highest price1 extraction (or none with refresh: false)
get_price_historyRecorded price and stock changes with current, lowest and highest priceNo extractions

Every tool is read-only and returns structured JSON with an output schema. Responses are trimmed for agents: bulky parts such as all variants, reviews and the description are included only when the agent asks for them.

Setup

  1. Subscribe to CartScout on RapidAPI. The free plan includes 300 extractions a month: plans.
  2. Copy your X-RapidAPI-Key from the RapidAPI dashboard.
  3. Add the server to your client. It runs with uv, which installs it on first use.
Claude Code
claude mcp add cartscout -e RAPIDAPI_KEY=your-rapidapi-key -- uvx cartscout-mcp
Claude Desktop

Settings → Developer → Edit config, then add:

{
  "mcpServers": {
    "cartscout": {
      "command": "uvx",
      "args": ["cartscout-mcp"],
      "env": { "RAPIDAPI_KEY": "your-rapidapi-key" }
    }
  }
}
Cursor

Add the same mcpServers block to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project).

Example prompts

CartScout reads product pages; it does not search stores. Give the agent product URLs, or let it find them with a web search tool first.

Configuration

VariableDefaultPurpose
RAPIDAPI_KEYrequiredYour RapidAPI key
CARTSCOUT_RAPIDAPI_HOSTcartscout-api.p.rapidapi.comRapidAPI host of the API
CARTSCOUT_API_URL, CARTSCOUT_API_KEYunsetUse a directly issued CartScout key instead of RapidAPI

The server sends only the product URLs your agent asks about to the CartScout API. Without a key it still starts and lists its tools (handy for MCP inspectors); each tool call then explains how to add RAPIDAPI_KEY.

Docker
docker build -t cartscout-mcp .
docker run -i --rm -e RAPIDAPI_KEY=your-rapidapi-key cartscout-mcp
HTTP transport

cartscout-mcp --transport streamable-http --port 8000 serves the tools at http://127.0.0.1:8000/mcp. Every client connected to it uses the key from the environment, so keep it on a private address.

Good to know

  • Prices follow each store's own region and currency.
  • Results can be cached for up to 60 minutes (cached: true).
  • Price history and deal ratings build up as products are read. A product seen for the first time has little history to compare against.
  • History range depends on the plan: 14 days on the free plan, up to 365 days on MEGA.
  • When a store blocks a request, the tool returns an error explaining it, and the failed request is not billed.
