Flipr X402

This gateway lets Claude place bets on a blockchain coin flip game running on Base. It connects to a smart contract that uses Chainlink VRF for provably fair randomness, where players pay USDC to flip and winning streaks claim accumulated pot rewards. You'd reach for this if you're building an AI agent that needs to interact with on-chain gambling mechanics or demonstrate autonomous crypto transactions. The implementation uses the streamable-http transport, so it works with remote MCP clients. Fair warning: this is real money on mainnet Base, not a testnet toy, so you're dealing with actual USDC and gas fees when your agent plays.
