@JiYiNo is talking about addons, so that would be a ‘yes’.
The Official Addons / Mosquitto is an mqtt broker that works well.
The Community Addons / MQTT Server & Web client has the same broker but also has Hivemq’s web client that you can use to subscribe or publish to topics for inspection/debugging. You can see more about it here: Home Assistant Community Add-on: MQTT Server & Web client
I use the first option in hassio and an install of mqttfx on my PC for mqtt debugging as I prefer the mqttfx interface.
