Cursor Launches Cross-Platform Agent Sandboxing, Cutting User Interruptions by 40%
Summary
Cursor launches cross-platform agent sandboxing across macOS, Linux, and Windows, using platform-specific security technologies to cut user interruptions by 40% while allowing AI agents to recover from failures and request elevated permissions when needed.
Key Points
- Cursor rolls out agent sandboxing on macOS, Linux, and Windows to reduce approval fatigue, with sandboxed agents interrupting users 40% less than unsandboxed ones.
- Each platform uses distinct sandboxing technologies — macOS leverages Seatbelt via sandbox-exec, Linux combines Landlock and seccomp for filesystem and syscall restrictions, and Windows runs the Linux sandbox inside WSL2.
- Agents are trained to understand sandbox constraints through updated tool descriptions and improved error surfacing, enabling them to recover gracefully from failures and request elevated permissions when needed.
