QuickJS Sandbox

An MCP server that provides a secure JavaScript execution environment using QuickJS compiled to WebAssembly. It exposes a single tool, 'run_javascript_code', which executes arbitrary JavaScript code within a sandboxed WASM environment, capturing stdout, stderr, and execution errors. The implementation uses Node.js's built-in WASI module and temporary files to safely isolate potentially untrusted code from the host system, making it ideal for language models that need to test or demonstrate JavaScript code without security risks.
