You can use

     \startTEXpage
         \processMPbuffer[…]
     \stopTEXpage

but loading a buffer in MPpage doesn’t work because the content of the 
environment
is just passed to MetaPost and buffers can’t be loaded inside MetaPost 
code unless
Hans adds a function for this, e.g.

     \startMPcode
         buffer("mybuffer")
     \stopMPcode
