PerformanceStudio vs shellguard

PerformanceStudio: Performance Studio is a cross-platform SQL Server execution plan analyzer that parses .sqlplan XML, identifies performance problems, suggests missing indexes, and provides actionable warnings via CLI or desktop GUI. It includes a built-in MCP server for AI-assisted analysis, supports live plan capture from SQL Server, and offers features like plan comparison, Query Store integration, and SSMS extension.; shellguard: ShellGuard is an MCP server that provides LLM agents with controlled, read-only bash access to remote servers over SSH. It parses and validates every command against an allowlist, blocking destructive operations with helpful suggestions. The LLM can connect, run diagnostics, inspect logs, query databases, and download files without manual context-switching.
