can you describe what can it be used for?
Can it parse out MDX requests into a logical plan? What is mdx logical plan class model?

Sounds like you are looking for an MDX engine. olap4j-xmlaserver's goals are much more limited: If you already have an MDX engine and an olap4j driver for it, then olap4j-xmlaserver will provide an XMLA interface to that engine.

olap4j-xmlaserver doesn't parse MDX, it just passes it through to the underlying olap4j driver.

Mondrian is, of course, an MDX engine that has an olap4j driver, and the one used by olap4j-xmlaserver most of the time. But now it is at least possible to write your own MDX engine and now have to write an XMLA interface as well.
