harlequin-mysql

This repo provides the Harlequin adapter for MySQL/MariaDB.

Installation

You must install the harlequin-mysql package into the same environment as harlequin. The best and easiest way to do this is to use uv to install Harlequin with the mysql extra:

uv tool install 'harlequin[mysql]'

Usage and Configuration

You can open Harlequin with the MySQL/MariaDB adapter by selecting it with the -a option and passing connection parameters as CLI options:

harlequin -a mysql -h localhost -p 3306 -U root --password example --database dev

Note: use -a mysql for both MySQL and MariaDB servers.

The MySQL/MariaDB adapter does not accept a connection string or DSN.

Many more options are available; to see the full list, run:
