In ConTeXt one can say:

\setupinteraction[state=start]
\setupcolors     [state=start]

\starttext

Hello There! \blank

\startMPcode
pickup pencircle scaled 5 ;
draw fullcircle scaled 4cm withcolor red ;
hyperpath "nextpage" boundingbox currentpicture ;
draw origin withcolor blue ;
\stopMPcode

\page This is an already pretty old feature and i must admit that i never 
use it.

\stoptext

The problem with this kind of functionality is that it is rather closely 
related to the way macro packages handle such things,
