DBHub

DBHub is a zero-dependency, token-efficient MCP (Model Context Protocol) server designed to allow MCP-compatible AI agents and tools to connect directly to relational databases like PostgreSQL, MySQL, MariaDB, SQL Server, and SQLite. It exposes tools for executing SQL queries, exploring database schemas, and defining custom, parameterized SQL actions, all from a unified interface. Secure by design, it offers guardrails such as read-only mode, row limits, and query timeouts, supports multiple simultaneous database connections, and includes a built-in web-based workbench for interactive management. DBHub is ideal for AI/ML engineers, data scientists, developers, and teams needing safe, efficient programmatic or conversational database access through AI clients like Claude and Cursor.
