MIcropython as MQTT broker

Hi, I am new to MQTT. I have it working with my ESP32 broad with my windows (or Rasb) as Mqtt broker.
wondering if it is possible to have the same ESP32 micro controller to be a mqtt broker (running Micro Python on it)
If so, any direction on how to do this?

Thanks,
James
