Overview

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.

FAQ from Dbhub

What databases does Dbhub support?

PostgreSQL, MySQL, MariaDB, SQL Server, and SQLite.

How do I install Dbhub?

Use Docker (docker run --rm --init --name dbhub --publish 8080:8080 bytebase/dbhub) or NPM (npx @bytebase/dbhub@latest) with required flags like --transport, --port, and --dsn. A demo mode is also available.

Does Dbhub require authentication?

The HTTP transport does not authenticate HTTP clients. For production, bind to 127.0.0.1 and use a reverse proxy or firewall.

What safety controls does Dbhub provide?

Read-only mode, row limiting, and query timeout to prevent runaway operations.

Is there a web interface?

Yes, Dbhub includes a built-in Workbench that provides a visual way to execute queries, run custom tools, and view request traces without needing an MCP client.
