Navigate to the handbook page for MuseScore 3: Plugins
Plugins are small pieces of code that add a particular feature to MuseScore. By adding a plugin, a new menu will be appended to the Plugins menu in MuseScore to accomplish a given action on the score or a part of it. Plugins are a way to let users with minimal programming skills add features to the software.
Some plugins are already delivered with MuseScore, see →below. You can find more plugins in the plugin repository. Some plugins there work with MuseScore 2; others will only work with older versions of MuseScore.
Note that some plugins may require the installation of other components (fonts, e.g.) to work. Check the plugin's documentation for more information.
Most plugins are provided as ZIP archives, so download the plugin's .zip file and uncompress it to one of the directories mentioned below.
Some may be provided directly as a .qml file, download and place into one of these directories.
MuseScore looks for plugins in
%ProgramFiles%\MuseScore 2\Plugins (or
%ProgramFiles(x86)%\MuseScore 2\Plugins for the 64-bit versions) and in
%LOCALAPPDATA%\MuseScore\MuseScore 2\plugins on Vista and Seven or
C:\Documents and Settings\USERNAME\Local Settings\Application Data\MuseScore\MuseScore 2\plugins (adjusted to your language version) on XP.
Mac OS X
On Mac OS X, MuseScore looks for plugins in the MuseScore bundle in
/Applications/MuseScore 2.app/Contents/Resources/plugins and in
~/Library/Application Support/MuseScore/MuseScore 2/plugins. To be able to move files in the app bundle, right click (Control-click) on MuseScore.app and choose "Show package contents" to reveal the
Contents directory. Be careful to use

Here also the documentation of all available elements can be found
Plugins installed by default
Some plugins come pre-installed with MuseScore, but they are not enabled by default. See →above to enable plugins.
This plugin imports ABC text from a file or the clipboard. Internet connection is required, because it uses an external web-service for the conversion, which uses abc2xml and gets send the ABC data, returns MusicXML and imports that into MuseScore.
Break Every X Measures
This plugin enters line breaks in the interval you select on the selected measures or, if no measures are selected, the entire score. It is no longer being distributed and has been replaced by Edit → Tools → Add/Remove Line Breaks. If you ever used an early beta version of MuseScore 2, though, you may still see the plugin left over.
Notes → Color Notes
This demo plugin colors notes in the selection depending on pitch. It colors the note head of all notes in all staves and voices according to the BoomWhackers convention. Each pitch has a different color. C and C♯ have a different color. C♯ and D♭ have the same color.
To color all the notes in black, just run that plugin again (on the same selection). You could also use the 'Remove Notes Color' plugin for this.
This demo plugin creates a new score. It creates a new piano score with 4 quarters C D E F. It's a good start to learn how to make a new score and add notes from a plugin.
This demo plugin shows some basic tasks.
Notes → Note Names
This plugin names notes. It displays the English names of the notes (as a staff text), for voice 1 and 3 above, for voice 2 and 4 below the staff, chords in a comma separated list, starting with the top note.
A translated version, which uses note names as per your language settings, is available from the plugin repository.

Some tools act as plugin as they "automate" some things, see Tools, actually some of those mentioned there used to be plugins.
