Autobox is an MCP server that lets AI agents sandbox themselves by running JavaScript in isolated V8 isolates and shell commands under macOS seatbelt, with per-call permissions for network, filesystem, CPU, and memory. It lowers the friction of sandboxing for agents that otherwise run unsandboxed, using copy-then-sync workspaces for safe host edits.

Target audience: AI agent developers, devops, backend devs
