Could use an alternative connection for write only which is ServerTap websocket

import shulker as mc
import time
import websocket

import time

authentication_key = "my-key"
url = "ws://localhost:4567/v1/ws/console"
ws = websocket.WebSocket()
ws.connect(url, cookie="x-servertap-key=" + authentication_key)

mc.connect()

poster = {
    'rcon': lambda cmd: mc.post(cmd),
    'servertap': lambda cmd: ws.send(cmd)
}

ret = mc.post("sudo PortalHub /replacenear 300 stone,netherrack air")
time.sleep(2)

with ws.connect(url, cookie="x-servertap-key=" + authentication_key) as ws:
    for option in ['servertap']:
