MCP Clients MCP Server DatabasesDBHub is a zero-dependency, token efficient MCP server implementing the Model Context Protocol (MCP) server interface. This lightweight gateway allows MCP-compatible clients to connect to and explore different databases:
- Local Development First: Zero dependency, token efficient with just two MCP tools to maximize context window
- Multi-Database: PostgreSQL, MySQL, MariaDB, SQL Server, and SQLite through a single interface
- Multi-Connection: Connect to multiple databases simultaneously with TOML configuration
- Guardrails: Read-only mode, row limiting, and query timeout to prevent runaway operations
- Secure Access: SSH tunneling and SSL/TLS encryption
Supported Databases
PostgreSQL, MySQL, SQL Server, MariaDB, and SQLite.
MCP Tools
DBHub implements MCP tools for database operations:
- [execute_sql](https://dbhub.ai/tools/execute-sql): Execute SQL queries with transaction support and safety controls
- [search_objects](https://dbhub.ai/tools/search-objects): Search and explore database schemas, tables, columns, indexes, and procedures with progressive disclosure
- [Custom Tools](https://dbhub.ai/tools/custom-tools): Define reusable, parameterized SQL operations in your
dbhub.tomlconfiguration file
Workbench
DBHub includes a built-in web interface for interacting with your database tools. It provides a visual way to execute queries, run custom tools, and view request traces without requiring an MCP client.
Installation
Don't lose this
Three weeks from now, you'll want Dbhub again. Will you remember where to find it?
Save it to your library and the next time you need Dbhub, it’s one tap away — from any AI app you use. Group it into a bench with the rest of the team for that kind of task and you can pull the whole stack at once.
⚡ Pro tip for geeks: add a-gnt 🤵🏻♂️ as a custom connector in Claude or a custom GPT in ChatGPT — one click and your library is right there in the chat. Or, if you’re in an editor, install the a-gnt MCP server and say “use my [bench name]” in Claude Code, Cursor, VS Code, or Windsurf.
