Superhighway MCP

Web search for AI agents that pays for itself. An MCP server that gives any MCP-speaking agent (Claude Desktop, etc.) a real-time web search tool. Under the hood it pays Superhighway $0.001 per search in USDC via the x402 protocol, using your wallet - no API key, no signup, no human in the loop. It runs locally over stdio via the published package.

People connecting search tools to Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.
