What is Dbhub?

Dbhub is a zero-dependency, token-efficient MCP (Model Context Protocol) server that allows MCP-compatible clients to connect to and explore various databases. It supports PostgreSQL, MySQL, MariaDB, SQL Server, and SQLite through a single interface and is brought to you by Bytebase.

How to use Dbhub?

Install via Docker or NPM, then start with command-line arguments such as --transport, --port, and --dsn. For multi-database setups, use a TOML configuration file. Demo mode is available via --demo. The server also includes a built-in web interface (Workbench) for visual interaction.
