Is there a way to make a serial2mqtt gateway (e.g. a NodeMCU is getting MySensor data on the serial interface and should just bridge that to MQTT)?

Serial 2 MQTT Gateway
I have a moteino. This MCU has no WIFI. I want to forward all messages as the arrive in the moteino and forward thenm 1:1 to a MQTT broker (like mosquitto). And from there I will consume and process the messages with node-red and fhem/openhab in parallel.
This allows me to change the controller layer easily since the all support MQTT.
