DBHub

DBHub is a minimal database MCP server that connects Claude and AI editors to relational databases.

DBHub is a minimal database MCP server that connects AI tools like Claude Code, VS Code, and Cursor to multiple relational databases through a single interface. It serves as the official example in the Claude Code docs for connecting to PostgreSQL via MCP. The software supports PostgreSQL, MySQL, MariaDB, SQL Server, Oracle, and SQLite simultaneously using TOML configuration. It provides features such as read-only mode, row limiting, query timeouts, SSH tunneling, and SSL/TLS encryption for secure access. Users can execute SQL queries, search schema objects, explain query execution plans, and define custom parameterized operations.
