JustHandled Agent Client MCP

A local MCP server and TypeScript client for the JustHandled Agent Utility Gateway, exposing thirty-two guarded utilities including preflights and maintained-data lookups. It facilitates agent interactions over USDC x402, ensuring security by failing closed before signing and validating payment terms. The server supports both free inspection and paid evidence-heavy products, returning versioned receipts for all transactions.
