First Dollar MCP

First Dollar is an MCP server that educates AI agents on using their own crypto wallets for x402 payments. It provides a curriculum of 16 lessons covering wallet concepts, USDC, and the Agent Payments Protocol, along with reference tools for troubleshooting and testing. It explicitly does not hold keys, sign transactions, or act as a butler, ensuring the agent retains control and understanding of its funds.
