Display coordinates of the opponents?

In minecraft 1.12.2 can I use the mod-loader forge to display the coordinates of other players using any mod? So for example:

I'm on the server gommehd.net, play a round speeduhc, press a button (for example M) and get the coordinates (and possibly the direction) of all other players displayed.

If you can't play on these servers without cheating, then just leave it and do not screw up the fun of every player.

This is more of a hack client, unless you want all players to have this feature.
