Are MOSFET's voltage, not current, devices?

In reading the specs of a very well known line of amps that use MOSFET output transistors, I noticed that they have surprisingly low maximum output current.

I know that MOSFET's are said to mimic the operation of a vacuum tube (hence, the more tubey sound as compared to bipolar transistors). Is it also the case that, like tubes, they produce primarily voltage and not current?

Thanks in advance for your responses.
