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.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.
