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
Expected range: 1,500–2,500 tokens (initial), 400 tokens (cache hit)
Caching: Caches database connection config in .claude/cache/database/ for 7 days. Invalidated when connection strings change.
Early exit: Returns immediately if MCP server for the target database is already connected.
Patterns used: Grep-before-Read, early exit, template-based generation, caching
