A MediaWiki extension that implemented DiscourseConnect consumer, allows your MediaWiki instance login with Discourse account, and more features are working in progress.
WARNING: It’s a crude extension that may have bugs that harm the security of your website.

Yep, just OAuth, although I’m not sure how much custom work there was to support it (I vaguely remember something about differing OAuth spec versions).
