Use next shortcode:
[mdf_value key='medafi_textinput' post_id=5 reflection=0]
- key - meta key
- post_id - ID of the post where its value should be taken. You have to set it if you are going to use this shortcode out of single post page. If inside of single page, you can skip it.
- reflection - set 1 if you are sure that this meta key is reflected, for example price
