MUD Protocol Reference

Comprehensive guide to Multi-User Dungeon communication protocols - everything you need to understand how MUDs communicate with players and servers.

What are MUD Protocols?

MUD protocols are standardized communication methods that enable enhanced functionality between Multi-User Dungeon (MUD) servers and clients. These protocols extend the basic Telnet connection to provide features like structured data exchange, compression, terminal capability negotiation, and rich user interfaces.

Most MUD protocols are implemented as Telnet options, following RFC854 and RFC855 specifications for option negotiation. They allow servers and clients to discover each other's capabilities and exchange information beyond simple text.
