Score: 6.0/10 (Innovation: 6, Technical: 5, Documentation: 7, Utility: 6)

Act SDK is a TypeScript library that enables developers to wrap existing functions as MCP (Model Context Protocol) tools with minimal code changes. It's interesting because it abstracts away the complexity of building MCP servers, allowing existing application logic to be exposed to AI agents without requiring separate infrastructure or deep MCP knowledge.
