Summary

A universal database MCP server — one integration for PostgreSQL, MySQL, SQL Server, SQLite, and MariaDB.

Features

One server for Postgres, MySQL, SQL Server, SQLite, and MariaDB
Token-efficient schema exposure for large databases
Read-only mode and SSH tunnel support

Installation

Set up this MCP server in your favorite AI agent — copy a ready-made configuration below.

Any MCP-compatible agent

Most agents (Claude, Cursor, Windsurf, VS Code, and more) read a standard mcpServers configuration.

Open your agent's MCP configuration file.
Merge the snippet below into it.
Restart the agent — the "DBHub" tools will be available.

{
  "mcpServers": {
    "dbhub": {
      "command": "npx",
      "args": [
        "-y",
        "@bytebase/dbhub",
        "--transport",
        "stdio",
        "--dsn",
        "postgres://user:pass@localhost:5432/db"
      ]
    }
  }
}

Claude Code

Add the server with a single CLI command.

claude mcp add dbhub -- npx -y @bytebase/dbhub --transport stdio --dsn postgres://user:pass@localhost:5432/db

Claude Desktop

Add the server to claude_desktop_config.json (Settings → Developer → Edit Config).

Description

DBHub is a single MCP server that speaks to every common relational database, which saves configuring and maintaining a different server per engine.

Supported databases

PostgreSQL, MySQL, MariaDB, SQL Server, and SQLite, all through one connection-string interface.

What makes it practical

Token efficiency. Schema information is exposed compactly, which matters enormously on a database with hundreds of tables — naive schema dumps consume the entire context window before a query is written.
Read-only mode, enforced at the server rather than trusted to the model.
SSH tunnelling for databases that are not directly reachable, which is most production databases.
Multiple transports — stdio for local clients, HTTP for remote deployment.
A demo mode with a sample database, so you can evaluate it without pointing it at anything real.

Setup

npx @bytebase/dbhub --transport stdio --dsn "<connection string>". Built and maintained by Bytebase, whose main product is database change management, so the operational instincts show.
