Score: 7.3/10 (Innovation: 7, Technical: 8, Documentation: 7, Utility: 7)

Lilith-Zero is a Rust-based deterministic security middleware for LLM agent systems that interposes at the transport layer to enforce access control, taint tracking, and audit logging on MCP tool calls. It is interesting because it addresses the emerging security needs of AI agent ecosystems with a fail-closed, type-safe architecture and integrates with multiple agent frameworks like Claude Code, GitHub Copilot, and OpenClaw.

Target audience: backend devs, security engineers, ai engineers
