# 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](https://api-production-17e1.up.railway.app) **$0.001 per search in USDC** via the [x402](https://x402.org) protocol, using *your* wallet — no API key, no signup, no human in the loop. ## Install Add to your MCP client config (e.g. Claude Desktop's `claude_desktop_config.json`): ```json { "mcpServers": { "superhighway": { "command": "npx", "args": ["-y", "github:patwalls/superhighway-mcp"], "env": { "AGENT_PRIVATE_KEY": "0xYOUR_FUNDED_BASE_WALLET_KEY", "X402_NETWORK": "base" } } } } ``` Restart your client. The agent now has three tools that do the whole search job — **web_search** (live, ranked results), **news_search** (recent articles with dates), and **scrape** (read any URL as clean markdown). Find it, read it, pay per call. ## Wallet `AGENT_PRIVATE_KEY` is a wallet you control, funded with a little **USDC on Base** (each search costs $0.001; gas is covered by the facilitator, so you don't need ETH). The key only ever signs tiny USDC payments — keep it to a small balance. Want to try free first? Set `X402_NETWORK=base-sepolia` and fund the wallet from a [Base Sepolia faucet](https://faucet.circle.com) to pay in test USDC. ## What you get `web_search` (web) and `news_search` (recent news) each return results as JSON: ```json { "query": "...", "count": 5, "results": [ { "title": "...", "url": "...", "description": "..." } ] } ``` --- Powered by [Superhighway](https://api-production-17e1.up.railway.app) — the web-search API agents pay for.
