🧙♂️ Simplified JavaScript Execution Environment
A streamlined direct Node.js execution environment that enables seamless code execution with full support for:
- ESM Modules - Native import/export syntax
- Dynamic Imports - Full support for await import()
- CommonJS compatibility - Works with require() through createRequire
- Native Node.js API access - Direct access to all Node.js features
🧩 Configuration
For Claude Code:

For Cursor, update your .cursor/mcp.json configuration:
local-only server
The server can only run on the client's local machine because it depends on local resources.
