metafun loads plain to so that's why there is a clash

you can try running with --metafun

alternatively, if you're not too dependent on latex you can wrap the mp 
code in

\startMPpage
...
\stopMPpage

and process that with the 'context' command. (In the latest context you 
can directly process mp files using the 'context' command.)
