I followed the instructions from Mopidy's website step-by-step including brew install python. After running brew install mopidy and the apprent successful installation and build of mopidy, it seems to not actually be installed.
This is the result of brew info mopidy:

To have launchd start mopidy/mopidy/mopidy now and restart at login:
brew services start mopidy/mopidy/mopidy
Or, if you don't want/need a background service you can just run:
mopidy
If I run mopidy:
-bash: mopidy: command not found
