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
claude mcp add x402-wallet \ -- npx x402-wallet-mcp
# ✓ Wallet created
# ✓ All endpoints ready
# ✓ Pay with USDC on Base
