MXP stands for Mud Extension Protocol.
It is a method for MUD servers to specify formatting and content information which goes beyond the scope of what is available with ANSI escape codes. For instance, using MXP a server can designate a line as a room description, exit, hyperlink, and so on.
For example:
This word is <b>bold</b>.
<RoomDesc>This is a room description</RoomDesc>
MUSHclient support
MUSHclient supports most of the MXP features as documented in the MXP specs. When receiving MXP commands from a MUD you will probably see hyperlinks (that you can click on) and pop-up menus (by right-mouse clicking on a link).
Server support
Various MUDs now support MXP. Probably one of the best is in the Dawn Of Time server, which has extensive support. Various other MUDs also have MXP support.
