This is the code i’m using:

var mineflayer = require('mineflayer');
var bot = mineflayer.createBot({
  host: "server.ip",
  port: 25565,
  username: "email",
  password: "password",
  version: "1.8"
});
bot.on('spawn', function() {
    bot.chat("/server ruby");
});

Tried setting up a bungeecord locally with 2 servers and it worked. Player logged in as bot has permissions to /server
