I hoped to be able to make an executable MetaPost source file by writing:

#!/usr/bin/env mpost -no-parse-first-line
\relax % Needed?
%MetaPost code goes here

but it doesn't work:

This is MetaPost, Version 1.005 (Web2C 7.5.7)
>> #!
>> usr
! Not implemented: (unknown numeric)/(unknown numeric).
<to be read again> 
l.1 #!/usr/
           bin/env mpost -no-parse-first-line

Has -no-parse-first-line indeed any effect?
