• 2

  Generate or explain SQL for multiple database engines (PostgreSQL, MySQL, MariaDB, SQL Server, SQLite) with contextual knowledge of the schema.

Description

DBHub is an open-source MCP (Model Context Protocol) server by Bytebase that exposes database schema, tables, indexes, and procedures and provides tools to generate, explain, and execute SQL. It supports PostgreSQL, MySQL, MariaDB, SQL Server, and SQLite, with transports for stdio and HTTP, demo mode, SSH tunnel support, and read-only protections and row limiting for safety. Integrations are provided for agents and clients like Claude Desktop, Claude Code, Cursor, and VSCode/Copilot, making it easy to attach LLM-based agents to real or demo databases.
