May I ask why MetaFun depends on ConTeXt? In my simple world, MetaFun is
just a collection of macros for MetaPost, so I don't see where the TeX
format comes in.

That would be applicable in, say, a private document. However, I'd like
to use it in a package, so in the end the user should only need to say a
TeX command and it should result in a MetaPost graphic. And this should
be independent of the TeX format and not require an extra context run
(as this would need shell-escape).
So from your answer I conclude that an extra context run is the best
way; however, is there another way for me, even if some macro are
