dev-portal vs UCAI

dev-portal: The Chainstack Developer Portal is a Mintlify-powered documentation platform for Web3 development, offering comprehensive resources and an interactive RPC node API reference. It is designed for AI agent integration, providing structured capabilities and a hosted Model Context Protocol (MCP) server for enhanced retrieval and interaction.; UCAI: UCAI is a Universal Contract AI Interface that generates AI-callable tools from any smart contract ABI, enabling AI agents like Claude to interact with blockchain functionalities. It automates the creation of production-ready MCP servers, allowing LLMs to understand, query, and execute smart contract operations safely and efficiently.
