Node Code Sandbox MCP Overview

alfonsograziano/node-code-sandbox-mcp MCP server runs JavaScript inside isolated Docker containers and installs requested npm packages for each job. It supports one-off execution, persistent sandbox sessions, shell commands, stdout capture, and optional port exposure for detached processes. Use it when an MCP client needs to execute Node.js code without running it directly on the host, or when scripts need generated files returned from an ephemeral job. Docker must be installed and running, with access to the Docker socket.
