# Database Connection & Management I'll help you connect to and manage databases through MCP servers for data exploration, schema inspection, and queries. Arguments: `$ARGUMENTS` - database type (postgres, mysql, mongodb), connection details, or query ## Database Capabilities **Supported Databases:** - PostgreSQL (via MCP or native psql) - MySQL/MariaDB (via MCP or native mysql) - MongoDB (via MCP or native mongo) - SQLite (local database files) **Operations:** - Schema inspection and exploration - Safe query execution - Data exploration and analysis - Migration support ## Token Optimization This skill uses database-specific patterns to minimize token usage: ### 1. Database Configuration Caching (700 token savings) **Pattern:** Cache database connection details and configuration - Store config in `.database-connection-cache` (1 hour TTL) - Cache: DB type, connection string pattern, ORM tool, schema location - Read cached config on subsequent runs (50 tokens vs 750 tokens fresh) - Invalidate on config file changes (.env, schema.prisma, etc.) - **Savings:** 93% on repeat connections ### 2. MCP Integration for Database Operations (1,500 token savings) **Pattern:** Use MCP server for database interactions - Connect via MCP database server (200 tokens) - Execute queries through MCP (300 tokens) - No Task agents for database operations - Direct tool-to-database communication - **Savings:** 83% vs LLM-mediated database operations ### 3. Bash-Based Schema Inspection (1,000
