    Use Cases & Benefits

    • Enforces OS-level filesystem and network restrictions on arbitrary processes without using containers.
    • Leverages native OS sandboxing primitives and proxy-based network filtering for secure-by-default, minimal-access process isolation.
    • Use for sandboxing AI agents or local servers to restrict filesystem and network capabilities securely.
    • Use for running untrusted commands or scripts with fine-grained control over file and network access.
    • Use for developing and testing software that requires strict isolation without full container overhead.

    From the README

    A lightweight sandboxing tool for enforcing filesystem and network restrictions on arbitrary processes at the OS level, without requiring a container.

    srt uses native OS sandboxing primitives (sandbox-exec on macOS, bubblewrap on Linux) and proxy-based network filtering. It can be used to sandbox the behaviour of agents, local MCP servers, bash commands and arbitrary processes.

    Beta Research Preview

    The Sandbox Runtime is a research preview developed for Claude Code to enable safer AI agents. It's being made available as an early open source preview to help the broader ecosystem build more secure agentic systems. As this is an early research preview, APIs and configuration formats may evolve. We welcome feedback and contributions to make AI agents safer by default!
