IF you are using OP2 they have not finished implementing the local MQTT server (mosquito). It is coming soon. Thats why you may have a problems.
In easy ESP I have had success with both OpenHAB and Domoticz MQTT. OpenHAB seems easier.
Here is a screen shot of my current configuration on my esp for MQTT.
The controller IP is the local address of your pi. This one I am running on my home wireless network so the IP address of the Pi running mosquito is used.
I asked the same question about MQTT and OP2 a few weeks ago. They are pretty busy and plan to get to it. In the mean time you could always use OP 1.2 which has mosquito installed.
