public OnPlayerCommandText(playerid, cmdtext[])
{
    if(!strcmp(cmdtext, "/COMMAND")){
        if(IsPlayerAdmin(playerid)){ //The "IsPlayerAdmin" checks if the player is an RCON admin!
            //The command
        }
        else{ //If he's NOT an RCON admin
            //Do you wanna do something? Like a message?
        }
    }
    return 1;
}

So the "IsPlayerAdmin(playerid)"
