# @three-ws/x402-mcp

> Give any AI agent a self-custodial x402 wallet. Search the live bazaar, inspect an endpoint's price without paying, and pay_and_call any x402 service in USDC or $THREE from your own Solana key — real @x402 settlement, bounded by spend caps. No custodial wallet, no account.

@three-ws/x402-mcp is a Model Context Protocol server from three.ws. Install: `npx -y @three-ws/x402-mcp`.
