If you are in control of the export backend, you can directly process
the metapost source blocks during export and ignore/filter their output
as needed.

Or you can use "raw" results by default and format everything as you
wish in your Org Babel module programatically.

If above is not sufficient, you can install global export filters that
can transform the metapost blocks/source blocks/their results as you
need in other export backends.
