CRA AGENT MCP

An MCP server that enables AI agents to pay for x402 APIs in USDC on the Arc network. It provides tools for quoting prices, executing payments via Circle Gateway, checking balances, and retrieving receipts, all while enforcing a strict spending policy that the agent model cannot modify.
