Universal Contract AI Interface (UCAI)

ABI-to-MCP generator: turns any smart contract ABI into an MCP server agents can call.

Last commit Aug 17, 2026 · ★ 37

Website ↗Docs ↗GitHub ↗Demo ↗

Overview

UCAI is an open-source generator that converts a smart contract's ABI into an MCP server, covering DeFi protocols, ERC-20 tokens, NFTs, and arbitrary contracts. Instead of hand-writing MCP tools per contract, an agent builder points UCAI at an ABI and gets contract read/write tools an agent can call. Useful for quickly exposing bespoke or long-tail contracts to an agent stack; generated write tools still need the same key-handling care as any transaction path.
