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.
Install
Add to your MCP client config (e.g. Claude Desktop's claude_desktop_config.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 to pay in test USDC.
What you get
web_search (web) and news_search (recent news) each return results as JSON:
{ "query": "...", "count": 5, "results": [ { "title": "...", "url": "...", "description": "..." } ] }
Powered by Superhighway — the web-search API agents pay for.

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
