MUSHclient (version 3.10 onwards) supports MXP - the Mud eXtension Protocol.
You can read about MXP at MXP design notes on this site.
The official MXP spec is at Zugg's site: MUD eXtension Protocol Specifications.
The purpose of this part of our forum is to discuss issues arising from MXP, in order to assist
- Implementors of MUD servers, so they understand how MXP is implemented on the client end
- Developers of other clients, so that clients can implement MXP in a consistent way
You are welcome to comment on MUSHclient's implementation, and also on the spec itself. If you have any problems implementing MXP on your server, please let us know so we can suggest solutions.
