Build Secure AI SQL Server Agent with C# and MCP

A new guide details how to build a secure AI database agent using C# and the Model Context Protocol (MCP). This server allows AI models like Claude Desktop and VS Code's Copilot to query SQL Server databases directly. The system incorporates multiple safety layers, including a read-only database user, a T-SQL parser with an allow-list, cost limitations, and row caps to prevent malicious queries. AI

IMPACT Enables AI models to securely interact with and query SQL databases, potentially streamlining data analysis workflows.

RANK_REASON The item describes a technical guide for building a specific tool (an AI database agent) rather than a core AI model release or research.
