## Overview The DB MCP Server provides a standardized way for AI models to interact with multiple databases simultaneously. Built on the [FreePeak/cortex](https://github.com/FreePeak/cortex) framework, it enables AI assistants to execute SQL queries, manage transactions, explore schemas, and analyze performance across different database systems through a unified interface. ## Core Concepts ### Multi-Database Support Unlike traditional database connectors, DB MCP Server can connect to and interact with multiple databases concurrently: ```json { "connections": [ { "id": "mysql1", "type": "mysql", "host": "localhost", "port": 3306, "name": "db1", "user": "user1", "password": "password1" }, { "id": "postgres1", "type": "postgres", "host": "localhost", "port": 5432, "name": "db2", "user": "user2", "password": "password2" } ] } ``` ### Dynamic Tool Generation For each connected database, the server automatically generates specialized tools: ```go // For a database with ID "mysql1", these tools are generated: query_mysql1 // Execute SQL queries execute_mysql1 // Run data modification statements transaction_mysql1 // Manage transactions schema_mysql1 // Explore database schema performance_mysql1 // Analyze query performance ``` ### Clean Architecture The server follows Clean Architecture principles with these layers: 1. **Domain Layer**: Core business entities and interfaces 2. **Repository Layer**: Data access implementations 3. **Use Case Layer**: Application business logic 4. **Delivery Layer**: External interfaces (MCP tools) ## Features - **Simultaneous Multi-Database Support**: Connect to multiple MySQL and PostgreSQL databases concurrently
