mycli is an interactive command-line client for MySQL, MariaDB and Percona Server. It enhances the conventional database shell with context-aware completion, syntax highlighting and tools for exploring query results.
The application suggests SQL keywords, table names, column names and other database objects while users type. Its completion system considers the context of the query, reducing repetitive typing and helping users construct statements more efficiently. Syntax highlighting is provided through Pygments, with configurable colour schemes.
mycli supports saved queries, searchable command history and several output formats. Queries can be redirected to files or external commands, while optional integrations allow tabular results to be processed using Polars dataframes and exported to formats such as Parquet. Users can also inspect query output through external interactive tools.
The application offers configurable keyboard bindings, secure credential storage and integration with SSH and other connection mechanisms. It is designed for database administrators and developers who prefer terminal-based workflows without sacrificing convenience.
This is free and open source software.
