Perplexity open sources numbat to monitor risky ai coding agents

Perplexity has released Numbat, an open-source tool designed to monitor the activities of AI coding agents on local endpoints. The utility provides detection and opt-in blocking capabilities to prevent unauthorised or dangerous actions by autonomous systems. This follows growing security concerns regarding the direct access AI agents have to development environments.

For enterprise teams deploying autonomous agents, Numbat offers a layer of observability and safety to mitigate risks like data exfiltration. It addresses the critical trust gap between agentic capabilities and strict enterprise security requirements.

  • Numbat monitors agent activity on endpoints to detect potentially malicious behaviour
  • It provides developers with the ability to opt in to blocking specific risky actions
  • The tool is open source to allow for community contributions and transparent security auditing
