Other than the plugin, there are no other 'Tools' available. However, there are a lot of resources and examples, which are laid down with the installer. Any programming language that can access REST API's and/or run COM objects will work. You can find several examples here...
1. Rest API example calls (recommended) - C:\Program Files\Quest Software\Toad DevOps Toolkit x.x\examples
2. COM examples - C:\Program Files\Quest Software\Toad DevOps Toolkit x.x\examples\COM
In both of those paths, x.x is the version of Toad DevOps Toolkit.
