What is the BuyWhere MCP MCP server?

Built for AI agent commerce, BuyWhere connects directly to Claude Desktop, Cursor, and other MCP clients. Agents can search by keyword or price range, retrieve full product specs, and compare options side-by-side in a single workflow.

The package is distributed via npm and requires only an API key to run over stdio. It supports cross-border shopping scenarios and includes tools for deal discovery and affiliate tracking.
