This is kind of like phoning your doctor and telling him you have a spot - and asking what it could be 
If the motor runs strong through the rev range it is unlikely to be the crank issue I'd say.
Engine mounts - a good starting point.
Best thing is to visit your doctor - I mean MX5 mechanic.

What RPM is the idle speed at? If the idle speed is low it will be a bit rough.

I would suggest getting a mechanic to look at it. If you adjust up the idle to around 1000rpm does it keep doing it?

buy a Haynes manual- small investment for a reference source. When were the plugs last changed etc ?

Its not the plugs that can be a issue, rather the plug leads...
It sounds to me like you have the classic idle droop problem where the manual idle speed is set too low.
The manual idle control is located on the top of the throttle body. You'll need to bridge the 10 and gnd terminals in the engine diagnostics box to put the car in manual idle speed mode rather than ECU controlled idle. You then adjust the manual idle via the screw and match it to the ECU idle by unplugging the briding wire in the diagonstics box. when the idle doesn't change irrespective of it being bridged or not you've got it right.
Make sure the car is warmed up properly when you do this otherwise you'll cause it to idle ever worse and possibly stall.
