## Description

A multi-database MCP server that provides secure SQL query execution across MySQL, PostgreSQL, and SQLite databases with granular permission controls and enterprise-ready features. Built with an adapter pattern for extensibility, it supports both single-database and multi-database modes, schema-specific permissions for different operations (INSERT, UPDATE, DELETE, DDL), SSL/TLS connections for cloud databases, and Unix socket connections for local setups. The implementation emphasizes security through read-only mode by default, transaction-based query execution, and configurable write operation permissions, making it suitable for controlled database access in production environments.
