anchor-x402-mcp

An MCP server exposing 14 anchor-x402 services as agent tools for pay-per-call USDC payments on Base mainnet. It enables agents to anchor hashes, screen wallets, decode transactions, and resolve names using the x402 protocol, requiring a funded EVM private key for the stdio transport.
