Strands Box runs AI agent programs inside a sandbox that restricts what they can execute, read, write, and reach on the network. It combines operating-system isolation with semantic policies written in the Dogwood language, evaluated by an embedded local engine that denies operations by default. Configuration is done via box.toml and policy.dw, with an egress gateway and MCP broker routing agent operations through policy checks. The project is harness-agnostic, written in Rust, and supports macOS on Apple silicon and Linux.
