Gsmapper can be used to get such a map. It's not a mod but a patch - which means you've got to change the source code of your local copy of Minetest. It works independent of the server. Personally, I didn't find it very practical as the view range is naturally limeted (you can only see what the server has sent so far), and there seems to be no way to scale the size of the map on-the-fly during gameplay.
The general approach to the lack of maps is to consult overview-maps provided by the server as huge images for large-scale orientation, use /home and /spawn and whatever teleportation mods exist, and apart from that, don't bother.
