358-359: LGTM! Clean WSL detection implementation.The WSL detection logic is well-implemented and follows the standard approach of checking for "microsoft" in the platform release string.
360-385: Well-implemented WSL URL adjustment logic.The code correctly handles the WSL networking challenge where Windows applications need to access WSL services. The fallback mechanism ensures the service remains functional even if IP detection fails.
404-405: Good addition of debug logging for server name tracking.The debug logging will help troubleshoot configuration matching issues between installation and verification.
515-522: Good consistency improvement in server name generation.The server name generation now matches the install function logic, including proper handling of default folder names. This ensures reliable configuration checking.
src/frontend/src/pages/MainPage/pages/homePage/components/McpServerTab.tsx (1)
412-412: Excellent UX improvement for the success message.The updated message clearly informs users that a client restart may be needed, which aligns perfectly with the backend MCP configuration changes and helps prevent user confusion.

This pull request enhances the handling of configurations for MCP servers, particularly in WSL environments, and improves logging for better debugging and user feedback. Key changes include introducing WSL-specific logic for determining configuration paths, adding detailed debug logs, and updating user-facing messages.
