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 dis...
