SQL Server MCP
One MCP entry, every SQL Server you administer. Connections live in a single connections.json, grouped by client or environment, hot-reloaded without restarting your AI agent - plus execution plans, index audits and stored-procedure analysis. It runs locally over stdio via the published package.
People who work with database, dba and execution plan and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.
