* refactor(frontend): improve McpServerTab with separation of concerns and type safety - Extract business logic into useMcpServer custom hook - Move utility functions to mcpServerUtils for better organization - Extract memoized components to McpCodeDisplay for reusability - Remove all 'any' types and add proper TypeScript typing (ToolFlow, HandleOnNewValueParam) - Improve code readability by separating UI from business logic - Fix critical bugs: handleOnNewValue callback, selectedPlatform parameter passing - Add generateApiKey to authStore for centralized API key management Component structure: - McpServerTab: Pure UI component (state + rendering) - useMcpServer: Business logic hook (API calls + data transformation) - mcpServerUtils: Pure utility functions - McpCodeDisplay: Reusable memoized components * fix(frontend): fix sidebar cookie state and use-mobile event listener cleanup - Fix sidebar cookie to use computed next value instead of stale state - Fix use-mobile hook to properly remove event listener on cleanup * refactor(frontend): extract McpServerTab sections into focused components - Move computed values (hasAuthentication, isAuthApiKey, hasOAuthError) to useMcpServer hook - Extract McpFlowsSection component (45 lines) - Tools selector UI - Extract McpAuthSection component (82 lines) - Auth status and configuration - Extract McpJsonContent component (85 lines) - JSON display with platform tabs - Extract McpAutoInstallContent component (101 lines) - Auto-install UI - Improve extractInstalledClientNames to filter undefined values for type safety Component improvements: - McpServerTab reduced from 385 to 181 lines (53% reduction) - Better separation of concerns - each section handles one responsibility - Main component is now pure presentational component - All components follow Mcp naming convention - No linting errors, proper TypeScript types throughout * refactor(frontend): merge McpCodeDisplay into McpJsonContent for better cohesion - Move MemoizedApiKeyButton and MemoizedCodeTag into McpJsonContent - Delete McpCodeDisplay.tsx (now redundant) - Keep related code together - memoized components are only used by JSON display - Reduce total component count from 5 to 4 files * refactor(frontend): organize types and interfaces at the top of McpJsonContent -

SUMMARY
Refactored McpServerTab.tsx following separation of concerns principle to improve code organization and type safety.
CHANGES
-> Separation of Concerns
- Extracted business logic into useMcpServer custom hook
- Moved utility functions to mcpServerUtils.tsx
- Split UI into 4 focused section components:
- McpFlowsSection - Tools selector
- McpAuthSection - Auth status and configuration
- McpJsonContent - JSON display with syntax highlighting
- McpAutoInstallContent - Auto-install interface
- Main component reduced from 741 to 181 lines (now pure presentational)
-> Type Safety
- Removed all any types, added proper TypeScript interfaces
- Organized types/interfaces at top of files
- Added generateApiKey to authStore for centralized management
- Bug Fixes
- Fixed sidebar cookie state bug (was using stale state)
- Fixed use-mobile hook event listener cleanup
- Testing
- Added 77 unit tests:
- 35 component tests (user flows, UI behavior)
- 7 hook tests (business logic)
- 28 utility tests (pure functions)
- 7 bug fix tests (sidebar, use-mobile)
All tests passing, including verification that tests catch regressions.
