When I run this example with mpost amd mptopdf, everything is fine.
But running it with context mkiv, using its mplib I get
an error.
The problematic command is dotlabels.top(0,1,2,3,4,5,6);
Commented it out, then it works with context, too.

Yes, you would. This is the text from
http://wiki.contextgarden.net/MkIV_Differences about metapost in context
mkiv:
All inline metapost code in your document is executed in a large
continuous run.
This means there are two things you have to watch out for:
You should load the MP packages you need in
\startMPinclusions..\stopMPinclusions; not inside a graphic.
You have to make sure that you do not re-state equations that were
already solved in a previous graphic.
These are in fact the exact same rules that you have to adhere to in
mkii if \runMPgraphicsfalse is active.
Best wishes,
Taco
