Shield KYA open-source agent tool-call auditing and gating
Understand this story
Shield Agent has open-sourced Shield KYA on GitHub to record every tool call made by AI agents, display audit trails in a local real-time dashboard, and check them against the Agent Trust Baseline. The open-source client is permanently free under the MIT license and requires Node.js 22 or later (24 recommended). The open-source client is only advisory and fails open on errors; only dangerous calls on a small "never list" are always denied. Actual blocking and human approval run on the MCP policy path for hosted workspaces (the Shield Agent cloud service).

- Hacker News AIShow HN: Shield KYA – Open-source audit trail and gate for AI agent tool calls
Shield KYA is an MIT-licensed CLI and local MCP gate that records every AI coding agent tool call on a live local dashboard and checks calls against a policy baseline, returning Allow, Review, or Deny. The open-source client is advisory and fails open except for a small never-list of dangerous calls, while real blocking and human approval run on the hosted MCP policy path. It installs via npm (@shield-agent/kya) and requires Node.js 22+, with plugins for Claude Code, Copilot CLI, Codex, and Gemini CLI.
