Let your agent write code and execute code directly in the browser with WASM

mcpsandbox provides a lightweight sandbox object inspired by Daytona-style ergonomics but built around command projection instead of a full VM or container. It maps capabilities into a minimal runtime and lets an agent use them through shell commands and a small typed API. It supports just-bash as the execution engine, built-in filesystem sandboxing, git integration, MCP-backed commands, TypeScript handlers, existing binaries, and external sandbox providers.

    WASM sandboxing is the right security model for untrusted agent-generated code.
