FAQ

What NestJS versions are supported?

The package is designed to work with modern NestJS versions. Check the package documentation for specific version compatibility.

Can I use this with non-NestJS Node.js applications?

While designed specifically for NestJS, the underlying MCP functionality could potentially be adapted for other Node.js frameworks, though this would require additional integration work.
