UsCmdRelay is a lightweight socket server designed for remote command execution on the host system based on defined comand relays. By utilizing authentication keys and command cluster definitions, it ensures authorized access.

This tool functions as a command executor rather than a remote shell, making it ideal for trusted environments like internal networks or VPNs.

Clients communicate with the server over TCP sockets using JSON format for data exchange. Before executing commands, the server authenticates clients with auth_keys, enabling precise control over command cluster access.
