SpendTheBits MCP

An official MCP server provided by SpendTheBits that enables AI agents to browse and purchase gift cards using USDC via the x402 protocol. It integrates with the SpendTheBits Superapp, allowing owners to set budgets, approve purchases, and manage card codes securely without the vendor holding funds.
