vscode-sandbox-runtime

This is an npm module and CLI for applying OS-level filesystem and network restrictions to arbitrary processes. This repository is a fork of Anthropic Sandbox Runtime, adapted for VS Code packaging and distribution.

How it works

• Install the @vscode/sandbox-runtime package as a dependency or global CLI.
• Configure filesystem and network restrictions in ~/.srt-settings.json, or pass a custom configuration with srt --settings .
• Run commands through the srt CLI, or use the exported SandboxManager API to wrap commands programmatically.
• The runtime applies native sandboxing primitives: sandbox-exec on macOS and bubblewrap/seccomp-based isolation on Linux.
• Network access is mediated through local HTTP and SOCKS proxy helpers so allowed and denied domains can be enforced for the sandboxed process tree.

Usage example

Install the package and run a command through the sandbox:

npm install -g @vscode/sandbox-runtime

cat > ~/.srt-settings.json {
await SandboxManager.reset()
})
