Method to get installed plugins remotely?

Hey guys,
some months ago, I stumbled accross some website, that listed custom plugins, installed on Rust servers. I am not sure, if someone added them on the site manually or if they retrieved it automatically. 

I found "oxide" is available at the steam server tags. So is there a way to get the oxide plugins, once found out oxide is installed?

Thanks in advance

You can use RCON and the 'plugins' command.

I'm pretty sure OP wanted to retrieve list of plugins on the server he plays at (without admin auth and without rcon access ofc).

Ah, then the answer would be nope.
I see. Thanks for both answers :-)
