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

Shield KYA is an open-source audit trail and policy gate for AI agent tool calls, recording every action on a local dashboard and checking calls against an Agent Trust Baseline. It integrates with MCP hosts like Cursor and Claude Code, offering fail-open local hooks and a hosted enforcement plane. The project addresses a growing need for agent observability and control, though its core enforcement is tied to a paid cloud service.

Target audience: AI engineers, DevOps, security teams
