gvyshnya · x · 2026-08-07
As AI agents gain widespread system-level access, controlling their behavior is becoming a key trend. Perplexity has open-sourced Numbat, a local monitoring tool designed to secure endpoints.
- Live Monitoring: Tracks activities of coding agents like Claude Code and Codex live on your local device.
- Proactive Blocking: Flags and can block high-risk actions before execution, such as reading SSH keys, accessing .env files, or grabbing browser cookies.
- After-the-fact Reconstruction: Accurately rebuilds the exact sequence of actions an agent took.
- Cross-Platform: Ships as a single binary for macOS, Linux, and Windows.
