Any recommendation of tool to evaluate any loss of functionality that this is not installed on server with AEM
This is not a clear question. Please try to make it clearer. I have no idea what you mean by a tool that specifies a loss of functionality.
As far as I know, there is no such tool to evaluate the loss of functionality that is not installed in AEM.
It means any ghost script we can install on server any loss of functionality that this is not installed on server
