All MCP operations already auto-sync to live configs:
- upsert_server() → sync_server_to_apps()
- toggle_app() → sync_server_to_app() or remove_server_from_app()
- delete_server() → remove_server_from_all_apps()
The manual 'Sync All' button was redundant and could confuse users
into thinking they need to manually sync after each change.
Changes:
- Remove 'Sync All' button from UnifiedMcpPanel header
- Remove useSyncAllMcpServers hook
- Remove handleSyncAll function and syncAllMutation state
- Remove RefreshCw icon import
- Remove sync-related i18n translations (en/zh)
Note: Backend sync_all_mcp_servers command remains for potential
future use (e.g., recovery tool), but is no longer exposed in UI.
Complete Phase 3 (P0) frontend implementation for unified MCP management:
**New Files:**
- src/hooks/useMcp.ts: React Query hooks for unified MCP operations
- src/components/mcp/UnifiedMcpPanel.tsx: Unified MCP management panel
- src/components/ui/checkbox.tsx: Checkbox component from shadcn/ui
**Features:**
- Unified panel with three-column layout: server info + app checkboxes + actions
- Multi-app control: Claude/Codex/Gemini checkboxes for each server
- Real-time stats: Show enabled server counts per app
- Full CRUD operations: Add, edit, delete, sync all servers
**Integration:**
- Replace old app-specific McpPanel with UnifiedMcpPanel in App.tsx
- Update McpFormModal to support unified mode with apps field
- Add i18n support: mcp.unifiedPanel namespace (zh/en)
**Type Safety:**
- Ensure McpServer.apps field always initialized
- Fix all test files to include apps field
- TypeScript type check passes ✅
**Architecture:**
- Single source of truth: mcp.servers manages all MCP configs
- Per-server app control: apps.claude/codex/gemini boolean flags
- Backward compatible: McpFormModal supports both unified and legacy modes
Next: P1 tasks (import dialogs, sub-components, tests)
