We used Dokuwiki in a similar situation. It's been a few years since I last used it (new client uses confluence) but I remember it was super easy to connect external tools. If your script can output text, Dokuwiki can display it :)
I have a docuwiki running on RPi at home (files are stored on a USB-connected HDD) as a personal knowledge management system. It doesn't even need any DB, just stores it in text files. Took just a few minutes to set up. Doesn't get any simpler (other than using plain text files on local of course :)
Is this a good choice for a company? These sorts of "hacker" solutions inevitably fall flat because people want a bunch of bells and whistles and don't mind things like never being able to find anything (arguably the single most important feature of a wiki) or being able to integrate their documentation with other systems.
It integrated well with our LDAP server. Its search is great, and everything is plain text so you can do whatever you like. It has a rich text editor but you can also edit plain text.
Dokuwiki has been my go-to solution for docs everywhere I've been for the past ten years or so unless they already have a (usable) wiki in place.
Trivial to set up. Trivial to migrate to, and from (should you ever need to). Doesn't need a database. There are lots of plugins available and it's sooo easy to write plugins for. Even if you hate PHP.
