Score: 5.8/10 (Innovation: 6, Technical: 6, Documentation: 6, Utility: 5)

Regentix is a policy enforcement proxy that sits between LLM clients and MCP servers, using Rego-based rules to govern tool execution and prevent destructive actions. It combines Rust, Python AI policy generation, and an Angular UI to offer a novel security layer for LLM tool use cases. The project is experimental but addresses a real gap in AI agent safety.

Target audience: backend devs, ai engineers, devops
