SQL Sentinel MCP Server
This server wraps SQL Server Extended Events in MCP tools so Claude can monitor production databases without ODBC. You get session lifecycle control, query fingerprinting, deadlock and blocking analysis, wait stats from sys.dm_os_wait_stats, and real-time event streaming. It also handles basic database operations like listing tables, describing schemas, and running SELECT/INSERT/UPDATE queries. Built on Microsoft.Data.SqlClient with native TDS protocol. Ships as a Docker container or .NET global tool. Useful when you need to diagnose slow queries, trace execution sequences, or let an agent interact with SQL Server metadata and performance counters directly from chat.
