If you are using Teleport, you may find the process of creating a database tunnel somewhat tedious.
Maulwurf is a simple CLI tool that will list available databases, login in and create a tunnel for the selected database.
$ npm install --global @mcombuec/maulwurf$ maulwurf [--port|-p <PORT_NUMBER>] [DB_NAME] [...<SEARCH_TERM>]
