Unfortunately it's no longer updated (Been more than a year since the last update) and is not on github.  
 
And stuff like the GUI interface is hardcoded to work with the versions in the package, so it's very hard to make changes yourself.  
 
So I ended up switching to 
Neard, which is on github and has several active developers. (Uniform Server only have one *absent* developer afik.)
And it's much easier to add other 3rd-parto tools to Neard.
