I have MathML that I need to render in my LaTeX document. Is there a recommended way of doing so?
So far, from googling, I've found MathParser – a Java converter. But I was hoping there might be a better way to do it.

tex4ht can convert to XHTML and MathML. See my answer to this question.
MathML is very verbose and is a pain to write manually, which is no problem if your code is automatically generated. For programs it is easy to parse, since it is XML.
TeX math code was designed to be written by humans and results in much shorter code. I cannot answer your question if one format will replace the other. As I mentioned they serve different purposes.
Is there any attempt to automatically transform one into the other that anyone is aware of?
I cannot speak for LaTeX, but in ConTeXt you can input MathML directly. Information about MathML in ConTeXt and the Wiki - MathML. Here is an example (credits to Hans Hagen) taken from one of the ConTeXt manuals:
\usemodule[mathml]
\starttext
\xmlprocessdata{}{
<?xml version="1.0" encoding="UTF-8"?>
<math xmlns="http://www.w3c.org/mathml" version="2.0">
<apply>
<eq/>
<apply>
<diff/>
<bvar>
<ci> x </ci>
</bvar>
<apply>
<root/>
<ci> u </ci>
</apply>
</apply>
<apply>
<times/>
<apply>
<divide/>
<cn> 1 </cn>
<apply>
<times/>
<cn> 2 </cn>
<apply>
<root/>
<ci> u </ci>
</apply>
</apply>
</apply>
<apply>
<diff/>
<bvar>
<ci> x </ci>
</bvar>
<ci> u </ci>
</apply>
</apply>
</apply>
</math>
}{}
\stoptext
The output:
For a TeX to MathML conversion, you can use the XML export, see ConTeXt wiki - epub and my answer to the question Converting ConTeXt document to HTML.

You can get TeX to parse the MathML, see for example xmltex, https://www.ctan.org/pkg/xmltex which comes with some mathml setup, however I wouldn't do it that way these days, I'd convert the MathML using XSLT, see for example pmml2tex which is available on github
