UCAI

MCP.Pizza Chef: nirholas

UCAI lets you connect your AI assistant (like Claude Desktop) to Ethereum and compatible blockchain smart contracts. By generating a custom server from any verified contract address, your AI can read, query, and simulate transactions on popular DeFi protocols such as Uniswap, Aave, NFTs, and more. This requires a developer setup but enables your assistant to understand and act on blockchain data in plain language without needing API keys.
