Securely executes arbitrary JavaScript code within a sandboxed QuickJS engine using Node.js WASI.
Sponsored
This server acts as an MCP tool provider, offering a secure method to execute JavaScript code. It exposes the `run_javascript_code` tool, which takes JavaScript code as input and executes it within a sandboxed QuickJS WASM environment. The server captures standard output and standard error streams, reporting any execution errors back to the MCP client, enabling safe execution of potentially untrusted JavaScript code snippets.
