Before optimization:
- McpPanel.tsx: 298 lines (component + business logic)
After optimization:
- McpPanel.tsx: 234 lines (-21%, UI focused)
- useMcpActions.ts: 137 lines (business logic)
Benefits:
✅ Separation of concerns: UI vs business logic
✅ Reusability: MCP operations can be used in other components
✅ Testability: business logic can be tested independently
✅ Consistency: follows same pattern as useProviderActions
✅ Optimistic updates: toggle enabled status with rollback on error
✅ Unified error handling: all MCP errors use toast notifications
Technical details:
- Extract reload, toggleEnabled, saveServer, deleteServer
- Implement optimistic UI updates for toggle
- Centralize error handling and toast messages
- Remove duplicate error handling code from component
