Database MCP Server provides a unified interface for connecting to and interacting with multiple database systems (SQLite, PostgreSQL, MySQL/MariaDB, and SQL Server) through a consistent set of tools. It features connection management, query execution, schema manipulation, and transaction support across all supported database types. The implementation uses a modular architecture with database-specific connectors that abstract away differences between database systems, making it ideal for applications that need to work with multiple database types or for AI assistants that require database access capabilities without dealing with database-specific syntax and connection details.
