Amazon MCP App

What it does

Amazon MCP App lets Claude search Amazon across multiple keyword phrasings, then surface the best picks in a scrollable carousel widget rendered directly inside your AI client. Users can toggle items into a cart and check out on real amazon.com — no copy-pasting ASINs.

It's a demo of the MCP Apps (interactive widget) surface built with @modelcontextprotocol/ext-apps. The live endpoint at https://amazon-mcp-app.vercel.app/mcp works out of the box with Claude Desktop via mcp-remote.

Key features

• Multi-search research — Claude calls search_amazon multiple times with varied phrasings to explore the product space before recommending.
• Interactive carousel widget — Amazon-styled (orange/yellow, star ratings, Prime badge) iframe rendered inside the MCP client.
• Add-to-cart flow — Toggle individual items, hit "Go to cart" to open the real Amazon cart URL with all selected ASINs.
• Cross-category bundles — Handles same-category comparisons and mixed bundles (e.g. keyboard + mat + lamp) in one widget.
• Stateless HTTP transport — Deploys to Vercel or any Node host; no session state to manage.
