ruby is what most command uses but anything default installed on osx is 
fine (which python are afaik).

about how commands call things then its fairly simple - the best article 
about I know is http://1klb.com/posts/2016/02/26/mailmate-bundles/

but in short using my org-mode bundle as example then you have:

A 
[plist](https://github.com/mailmate/org-mode.mmbundle/blob/master/info.plist) 
file to describe the extension - see the link above for how to make that

A 
[mmCommand](https://github.com/mailmate/org-mode.mmbundle/blob/master/Commands/Add%20With%20Summary.mmCommand) 
to define the action - here you'll see MM_* env vars being set using 
mail mates syntax for accessing elements. That is used to pass content 
to the scripts.
Since you need encoded you probably want to use "decoded" for how you 
want your input/output.

And then your [actual 
script](https://github.com/mailmate/org-mode.mmbundle/blob/master/Support/bin/add) 
which will be able to get the various MM_* vars.

hope that helps.
