DBHub

DBHub is a zero-dependency, token efficient MCP server implementing the Model Context Protocol (MCP). It allows MCP-compatible clients like Claude Desktop, Claude Code, Cursor, VS Code, and Copilot CLI to connect to and explore different databases through a single, unified interface. Built by Bytebase, the open-source database DevSecOps platform, DBHub is designed for AI-native database interactions. It supports multiple database types including PostgreSQL, MySQL, MariaDB, SQL Server, and SQLite through one consistent MCP interface. Key features include: - **Multi-Database Support**: Connect to PostgreSQL, MySQL, SQL Server, MariaDB, and SQLite through a single MCP server - **Token Efficiency**: Implements just two core MCP tools (execute_sql and search_objects) to maximize the AI context window - **Safety Guardrails**: Read-only mode, row limiting (default 100 rows), and query timeout protection prevent runaway operations - **Multi-Connection**: Connect to multiple databases simultaneously using a simple TOML configuration file - **Built-in Workbench**: Web-based UI for executing queries, running custom tools, and viewing request traces without an MCP client - **Secure Access**: SSH tunneling and SSL/TLS encryption support for secure database connections - **Zero Dependencies**: Runs standalone with Docker or npx — no external runtime dependencies required DBHub is perfect for AI developers who want their coding agents to safely interact with databases. Whether you're building with Claude, Cursor, or custom MCP clients, DBHub provides a clean, secure, and efficient bridge between AI agents and your data.
