For my plugin I have to intercept messages and commands sent (msg or command ex: "Hello word" or "/kill player1") by players or the console and check it before sending / executing they.

Is there any way to do it?

I'm using Spigot 1.18.1

You should use event. Firstly, register it in your onEnable() like that :

getServer().getPluginManager().registerEvent(new ManageChatAndCommandListener(), this);

Manage messages

To manage message, you should use AsyncPlayerChatEvent (Documentation) like that :

@EventHandler
public void onChat(AsyncPlayerChatEvent e){
   if(e.getMessage().equalsIgnoreCase("My not allowed message")) {
       e.setCancelled(true); // don't send the message
   }
}

Manage commands

To manage commands, you should use PlayerCommandPreprocessEvent (Documentation) like that :

@EventHandler
public void onCommand(PlayerCommandPreprocessEvent e){
   if(e.getMessage().equalsIgnoreCase("/not-allowed-command")) {
       e.setCancelled(true); // don't run the command
   }
}

Warn: the message correspond to the command, with the /. Even if most of people use /, you should just ignore the first char and not the / itself
