Anthropic releases open-source OS-level sandbox for AI agents

By PulseAugur Editorial · [2 sources] ·

Anthropic has released an open-source tool called sandbox-runtime (srt) that provides OS-level sandboxing for AI agents and other processes without using containers. This tool limits file and network access for applications, aiming to reduce the frequency of permission prompts for developers. It utilizes native OS isolation primitives, such as Seatbelt on macOS and bubblewrap on Linux, with alpha support for Windows. AI

IMPACT This tool could improve security and reduce developer friction when running AI agents and command-line programs.

RANK_REASON Open-source tool release from an AI lab, not a core model release.
