Overview
What is Mcp Sql Server?
A Model Context Protocol server that provides comprehensive access to SQL databases, starting with MSSQL support. It enables AI assistants to inspect database schemas, execute queries, and perform database operations with enterprise‑grade security and performance monitoring.
How to use Mcp Sql Server?
Install globally via npm install -g @donggyunryu/mcp-sql or run with npx -y @donggyunryu/mcp-sql. Create a .env file with your MSSQL credentials (DB_HOST, DB_PORT, DB_DATABASE, DB_USER, DB_PASSWORD). Then add the server configuration to your MCP‑compatible assistant (e.g., Claude Desktop, Cursor) using the provided JSON settings. Restart the assistant and start with natural‑language queries like “Show me all tables in my database.”
