-- **Ephemeral PostgreSQL Instances**: Create temporary PostgreSQL databases in Docker containers
+- **Multi-Database Support**: Create temporary PostgreSQL, MySQL, and MariaDB instances in Docker containers
 - **Dynamic Port Allocation**: Automatic port assignment to prevent conflicts (range: 15432-25432)
-- **Multiple PostgreSQL Versions**: Support for PostgreSQL 15, 16, and 17 (default: 17)
+- **Multiple Database Versions**: Support for various versions of each database type
+  - PostgreSQL: 15, 16, 17 (default: 17)
+  - MySQL: 5.7, 8.0 (default: 8.0)
+  - MariaDB: 10.6, 11 (default: 11)
 - **Superuser Access**: Auto-generated credentials with full database access
 - **MCP Integration**: Compatible with Augment Code and other MCP clients
 - **CLI Management**: Command-line tools for instance management outside of MCP
-- **Health Monitoring**: Built-in health checks for PostgreSQL instances
+- **Health Monitoring**: Built-in health checks for all database types
 - **Comprehensive Logging**: Structured logging with configurable levels and formats
