MUME Help

GENERIC MUD COMMUNICATION PROTOCOL, GMCP


The Generic Mud Communication Protocol (GMCP) allows for out-of-band information to be sent from the MUD server to the client.

The messages are sent as telnet commands, invisible to the player. Clients that support GMCP can receive such messages and also send GMCP messages to the game. See below for supported GMCP commands.

MUME tries to keep a level playing field for all players and clients by not providing additional information over GMCP that might disadvantage players on more basic clients.

Note: GMCP module and message names are not case-sensitive but message body key names are case-sensitive.

See https://www.gammon.com.au/gmcp and https://tintin.mudhalla.net/protocols/gmcp for more information on GMCP.

What is MUME?

MUME, Multi-Users in Middle-earth, is a multiplayer text-based online game based upon J. R. R. Tolkien’s Middle-earth during the epic wars of the late Third Age between the forces of the Dark Lord and the armies of the Free peoples. MUME is completely at no cost and has been continuously running, expanded, and remastered by a community of volunteers since 1991.
