tryx402 MCP

An open-source payment governance layer for AI agents that provides a budget router, idempotency, cost ledger, and multi-currency billing over x402 (USDC on Base). It acts as a safe, provider-agnostic wrapper over AgentCash, enabling agents to make paid calls with hard budget caps and signed receipts.
