E-Commerce Price Intelligence MCP Server

Compare product prices across Amazon, Walmart, Target, eBay, and Best Buy. See who has the best deal. Track price history. All from inside your AI assistant.

What This Does

You tell your AI assistant to check a product price and this server goes out and finds it across major retailers. Current prices, sale prices, ratings, images, direct links to buy. Everything you need to make a purchase decision or track the market.

Want to know if that AirPods deal is actually good? Check the price history and see what they normally sell for.

Want to compare across stores? One call gives you prices from Amazon, Walmart, Target, eBay, and Best Buy side by side.

This is an MCP (Model Context Protocol) server. Your AI assistant (Claude, GPT, or any MCP-compatible client) can call these tools directly in conversation. Ask "what's the best price for AirPods Pro right now" and your assistant does the work.

How It Works

1. Install this server in your MCP client (Claude Desktop, Cursor, or any MCP-compatible app)
2. Your AI assistant gets access to the tools below
3. Ask about any product and your assistant calls the right tool
4. Prices come back as structured data with links

No browser tabs. No coupon hunting. Just ask.
