Open-Source MCP Server
Give your AI agent a wallet.
One command installs a self-custodial USDC wallet. Your agent pays x402 endpoints automatically—no API keys, no accounts, no config.
x402 is an open payment protocol · USDC is a dollar-pegged stablecoin · Base is Coinbase's Ethereum L2
Works with Claude Code, Cursor, Windsurf, Claude Desktop, and OpenClaw. Claude Desktop setup guide →
