Like so much, that this feature is there now. But how to update description through MQTT? Did not find any hint.

@pepp86 You can change a description using the zigbee2mqtt/bridge/request/device/options topic, see documentation

Example:

mosquitto_pub -h "localhost" -u user -P "password" \
    -t "zigbee2mqtt/bridge/request/device/options" \
    -m '{"id": "ieee_addr or friendlyname", "options": {"description": "the new description"}}'

If you want the request the current description you can trigger a new publish of the device info using:

mosquitto_pub -h "localhost" -u user -P "password" \
    -t "zigbee2mqtt/bridge/request/device/options" \
    -m '{"id": "ieee_addr or friendlyname", "options": {}}'

The options of all devices will then be published to zigbee2mqtt/bridge/devices see documentation
