An open source step counter or foot pod with MQTT would be highly desirable. Adafruit offers a step counter in a fashionable housing:
Unfortunately, it offers no MQTT support. According to the Adafruit video instruction, it should be possible to add MQTT.
The Adafruit Step counter has an LCD display. It should be possible to compare step counting accuracy from a Suunto fod paired to a training tracker, a Stryd food pod paired to a training tracker with the Clue step counter LCD display.
In the Bitalino Forum, Bitalino published an instruction how to build a foot pod from Bitalino components with a step counting algorythm.
Unfortunately, the Bitalino forum is not available anymore:

Here is a paper about an IoT based Pedometer using Raspberry-Pi:

Unfortunately, it seems not to use MQTT either.
Rasperri PI ANT+ can be modified to support ANT+ foot pod:
The number of steps can be calculated from stride length and distance.
