An MCP server that charges your AI a penny per call
Short summary
An engineer built x402-extract-mcp, an MCP server that extracts structured product data from URLs and micro-charges AI agents $0.01 USDC per call, settled on-chain. Agents install via Claude Desktop/Cursor/Windsurf with zero signup friction—no API keys, no subscriptions. This exploits the growing x402 infrastructure (Cloudflare, Stripe shipping it) by offering agents a practical paid endpoint.
