btex .. etex returns a picture picked up from a file generated by a bunch
of mp tools.

it's metapost's btex etex btw

This is not needed in context since it saves environments and additional
data already. Also, this macro is rather hard coded -) 

see metafun manual: 

\startMPenvironment 
  \setupbodyfont[pos,12pt]
\stopMPenvironment 

So, for string composition purposes, one may define: 

vardef TEX primary s = 
  write "btex " &s " etex" & EOF to "mptextmp.mp" ;
  scantokens "input mptextmp"  
enddef ;  

But there are easier ways I think. 

Btw, i'm thinking of a different mechanism which permits making macros with
embedded btex/etex things,
