I've added a "--mapfiles" option to "mtxrun --script metapost" (the more 
modern replacement for mptopdf) and default to some base map files. Will 
be in next beta. In context itself (when embedding such graphics) one 
still need to include those map files. However, when
using mp graphics in context, it makes much more sense to define them 
runtime.

Alternatively, you can consider making your mp graphics like this:

\startMPpage
   some code
\stopMPpage

This will use the regular font system, gives access to everything 
context as well, and makes it possible to opentype fonts. The resulting 
(cropped) graphic can of course be included. One can also have more of 
them:

\starttext

\startMPpage
   some code
\stopMPpage

\startMPpage
   some code
\stopMPpage

\stoptext

and include the pages selectively.
