MSMP Enhanced

MSMP Enhanced is a server-side Fabric Mod that extends the Minecraft Server Management Protocol introduced in Minecraft 1.21.9 (25w35a).

This mod provides optional Unix socket support and adds additional RPC methods. MSMP Enhanced can also be used as a remote server console backend, similar to RCON but with support for structured Text Components and command tab completion. This allows external tools (like web panels or CLI utilities) to run commands, view styled output, and get live suggestions for commands as you type.
