Perplexity Open Sources Numbat To Monitor Risky AI Coding Agents

Perplexity open-sourced Numbat, a security tool for monitoring AI coding agents on laptops and workstations.

It uses hooks and session logs to flag suspicious behavior like secret access, privilege escalation, and data exfiltration.

Numbat works with Perplexity’s internal agent harnesses and supports macOS, Linux, and Windows.

The release reflects rising concern that AI agents can break out of constrained environments and create security risks on their own.
