Zero-dependency, token-efficient database MCP server for Postgres, MySQL, SQL Server, MariaDB, SQLite.
DBHub is a TypeScript MCP server that acts as a gateway between MCP-compatible clients and relational databases, supporting PostgreSQL, MySQL, MariaDB, SQL Server, and SQLite through a single interface. It exposes three MCP tools: `execute_sql` for running queries with transaction support and safety controls, `search_objects` for exploring schemas, tables, columns, indexes, and stored procedures via progressive disclosure, and `custom_tools` for defining reusable parameterized SQL operations in a `dbhub.toml` file. The server connects to Claude Desktop, Claude Code, and other MCP clients over stdio or HTTP transport, and can handle multiple database connections simultaneously from one instance. A built-in web workbench lets users run queries and inspect request traces without any MCP client. Notably, the entire server ships with zero external dependencies and intentionally limits itself to two core MCP tools by default to minimize token consumption, preserving context window space for developers, data analysts, and database administrators working with AI coding assistants.
