Hi all!
I developed this a while ago for personal use, but now that I've had a second to clean up the documentation a bit I figure I should share it with the community for feedback and to see if anyone finds it useful.
This is a basic requests wrapper that allows easy calling of MCC and MCWS commands from Python or the command-line. For example, I'm using linux and can't call MCC from the command line so this allows me to use MCC to set the rating of my songs via a hot key. I can also get information about currently playing tracks to display in my status bar. I also use it to get my media keys working. I also use it for mass updates of scraped genre tags. Other applications can include the development of other Python based plugins that need to interact with the JRiver database.
The project is available on github at:
