 A cross-platform SQL Server execution plan analyzer with built-in MCP server for AI-assisted analysis. Parses `.sqlplan` XML, identifies performance problems, suggests missing indexes, and provides actionable warnings — from the command line or a desktop GUI.
 
 Built for developers and DBAs who want fast, automated plan analysis without clicking through SSMS.
