CartScout tools (4)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • check_deal

    Rate whether a product's current price is a good deal compared with its recorded price history, with the average, lowest and highest price in the period. History builds up each time CartScout reads the product, so a product seen for the first time has little to compare against.

  • compare_products

    Compare 2-10 product pages side by side: cheapest, cheapest in stock, best rated, biggest discount, price spread and whether every page sells the same product (matching GTIN). Uses 1 extraction per URL and needs a paid CartScout plan (PRO or higher).

  • get_price_history

    Recorded price and stock changes of a product page, with the current, lowest and highest price. History exists only for products CartScout has read before; call get_product first to start it. Does not use extractions.

  • get_product

    Get the live price, stock status, discount, variants, identifiers (SKU, GTIN) and rating of one product page. Works with Shopify, WooCommerce, Walmart and eBay stores, Amazon in beta. Uses 1 extraction from the user's CartScout plan.

Install CartScout in Claude Code, Cursor or VS Code

Add to Cursor

What the publisher says

From the CartScout repository's README, as published. We do not edit it. Read it on GitHub

CartScout MCP server

<!-- mcp-name: io.github.Veselin15/cartscout-mcp -->

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

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

plans.

  1. Subscribe to CartScout on RapidAPI. The free plan includes 300 extractions a month:

first use.

  1. Copy your X-RapidAPI-Key from the RapidAPI dashboard.
  2. Add the server to your client. It runs with uv, which installs it on

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

  • "What does https://www.allbirds.com/products/mens-tree-runner-nz-ochre cost, and is size 10 in stock?"
  • "Is $79 a good price for this air fryer? https://www.walmart.com/ip/844320666"
  • "Compare these three listings and tell me the cheapest one I can buy today: …"
  • "Show me how the price of this product changed over the last two weeks."

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

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

Shortened. The full README is on GitHub.
