Trial costMedium lift

Testable in one sitting, but you will likely touch real infra or local setup before you know if it sticks.

Fastest way to find out if dbhub belongs in your setup.

Copy the install command, run a real test, and back it out cleanly if it slows you down.

Try now
claude mcp add dbhub -- npx dbhub

Run this first. You will know quickly if the workflow earns a permanent slot.

                 MCP Clients           MCP Server             Databases

DBHub 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: Execute SQL queries with transaction support and safety controls
  • search_objects: Search and explore database schemas, tables, columns, indexes, and procedures with progressive disclosure
  • Custom Tools: Define reusable, parameterized SQL operations in your dbhub.toml configuration 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.
