open-sourceNetwork analysis tool configuration for sniffing and debugging GMCP payloads between client and server.
Pros
- + Inspects raw negotiation sequences (IAC WILL/DO)
- + Validates JSON payload integrity
- + Independent of client/server logs
Cons
- − Difficult to use with encrypted (TLS) connections
- − Steep learning curve for packet analysis
Aardwolf GMCP Reference
freeA practical list of GMCP packages and sub-messages used by one of the largest MUDs, useful for testing client compatibility.
Pros
- + Shows real-world implementation of complex packages
- + Examples of map and quest data via GMCP
- + Proven at high scale
Cons
- − Specific to Aardwolf's custom engine
- − Documentation is wiki-style and non-linear
Mudlet GMCP Debugger Script
freeA Lua script for Mudlet that provides an on-screen console to view real-time GMCP traffic.
Pros
- + Instant visualization of incoming data
- + No external tools required
- + Easy to toggle during development
Cons
- − Can impact performance if traffic is heavy
- − Only works within Mudlet
GMCP (Generic MUD Communication Protocol)
freeA protocol used to send structured data (JSON) from the server to the client, enabling non-visual status bars and map data.
Pros
- + Allows clients to track HP/Mana without screen reader noise
- + Enables precise room and coordinate tracking
- + Decouples data from the main text stream
Cons
- − Requires server-side implementation
- − Complex to script client-side for novice users
