Need to connect Claude to SQL Server with proper Windows authentication? This gives you 12 tools for database exploration: list databases and tables, describe schemas with columns and constraints, map foreign key relationships, search across tables and procedures, and execute read-only SELECT queries with automatic timeouts. Ships with schema caching (60 minute TTL by default) and query validation to prevent writes. Windows version uses native ODBC with msnodesqlv8 for Windows Auth support, while the macOS fork uses the pure JavaScript mssql driver. Install via npx or clone for development. Good fit if you're running SQL Server locally and want natural language database queries without switching contexts.
