## Integration Roadmap: Phase Implementation

### 🔴 PHASE 1: IMMEDIATE SECURITY FIX (1-2 days) - CRITICAL

**Problem**: 5 widgets expose API keys to client-side code

**Widgets Affected**:
1. AgentChatWidget
2. AudioTranscriberWidget
3. ImageAnalyzerWidget
4. LiveConversationWidget
5. VideoAnalyzerWidget

**Solution**: Create MCP proxy routes for Gemini APIs

**Implementation**:
```bash
New routes in backend:
POST /api/mcp/gemini/chat          - Chat completions
POST /api/mcp/gemini/audio         - Audio transcription
POST /api/mcp/gemini/vision        - Image analysis
POST /api/mcp/gemini/video         - Video analysis
WebSocket /api/mcp/gemini/live     - Live multimodal streaming

Changes to widgets:
- Move GoogleGenAI initialization to backend
- Replace direct fetch with `/api/mcp/gemini/*` calls
- Remove client-side API key exposure
- Use secure JWT/session-based authentication
```

**Timeline**: 1-2 days
**Blocking**: Prevents moving widgets to production

---

### 🟡 PHASE 2: CONSOLIDATE NON-MCP APIs (3-5 days) - HIGH PRIORITY

**Problem**: 4 widgets use direct HTTP to backend services, bypassing MCP

**Widgets Affected**:
1. AiPalWidget
2. CmaDecisionWidget
3. EvolutionAgentWidget
4. SragGovernanceWidget

**Solution**: Route through MCP consolidation layer

**Implementation**:
```
Changes to backend:
- Add MCP routes that wrap existing `/api/{service}/*` endpoints
- Implement request/response standardization
- Add logging and monitoring at MCP layer

Changes to widgets:
- Replace direct localhost calls with `/api/mcp/{service}/*`
- Update error handling for standardized MCP response format
```

**Timeline**: 3-5 days
**Dependencies**: Requires Phase 1 patterns to be established

---

### 🟡 PHASE 3: REPLACE MOCK DATA WITH MCP (5-7 days) - MEDIUM PRIORITY

**Problem**: 6 widgets use hardcoded mock data instead of real backends

**Widgets Affected**:
1. IntelligentNotesWidget → `/api/mcp/notes/query`
2. MCPEmailRAGWidget → `/api/mcp/email/{inbox,suggestions}`
3. CybersecurityOverwatchWidget → `/api/mcp/security/threats`
4. AgentBuilderWidget → `/api/mcp/agents/{tools,registry}`
5. PromptLibraryWidget → `/api/mcp/prompts/{library,search}`
6. ProcurementIntelligenceWidget → `/api/mcp/procurement/opportunities`

**Solution**: Implement real backends and wire through MCP

**Implementation**:
```
For each mock widget:
1. Design MCP endpoint contract (request/response schema)
2. Implement backend endpoint
3. Update widget to call MCP endpoint
4. Remove mock data constants
5. Test end-to-end
```

**Effort Breakdown**:
- IntelligentNotesWidget: 2-3 days
- MCPEmailRAGWidget: 3-4 days (needs real RAG)
- CybersecurityOverwatchWidget: 4-5 days (threat integration)
- AgentBuilderWidget: 2-3 days
- PromptLibraryWidget: 1-2 days
- ProcurementIntelligenceWidget: 3-4 days

**Timeline**: 5-7 days
**Dependencies**: Can run in parallel with Phase 2

---

### 🟢 PHASE 4: POLISH CONFIGURATION UIs (3-4 days) - LOW PRIORITY

**Widgets**:
1. MCPConnectorWidget - Replace mock testing with real connection validation
2. Verify WidgetImporterWidget MCP integration pattern
3. Audit StatusWidget and SystemSettingsWidget

**Timeline**: 3-4 days
**Dependencies**: Can run after other phases complete

## Recommendations

### Immediate (This Week)
1. ✅ Complete Phase 1 security fix (secure Gemini API keys)
2. ✅ Create MCP proxy routes for all external APIs
3. ✅ Test LiveConversationWidget WebSocket reliability

### Short-term (Next Week)
4. ⏳ Phase 2: Consolidate non-MCP HTTP calls through MCP layer
5. ⏳ Phase 3: Begin real data backend implementation
6. ⏳ Start with highest-value widgets (MCPEmailRAGWidget, CybersecurityOverwatchWidget)

### Medium-term (Dec 1-15)
7. ⏳ Complete Phase 3: All mock data replaced
8. ⏳ Phase 4: Polish configuration UIs
9. ⏳ End-to-end testing with real data

### Quality Gates
- ✅ All widgets must pass security audit (no API keys in browser)
- ✅ All widgets must route through MCP for data access
- ✅ 95%+ test coverage for MCP integration points
- ✅ Performance: <100ms latency added by MCP layer

---

## MCP as "Foundation" - Reality Check

### Current State
- ✅ MCP infrastructure exists (backend, routing, tools registered)
- ✅ 1 widget demonstrates proper MCP usage (McpRouterWidget)
- ❌ MCP "foundation" is infrastructure-only, not integrated into widgets

### The Gap
- **Claim**: "MCP is the foundation for our solution"
- **Reality**: Only ~4% of widgets actually use it
- **Root Cause**: Widgets built before or without MCP wiring complete

### Path Forward
Completing this 3-phase roadmap (12-18 days) will transform MCP from "infrastructure only" to "actual foundation":
- ✅ 100% of widgets routed through MCP
- ✅ Centralized security (API key management)
- ✅ Unified service layer (all backends via MCP)
- ✅ European sovereignty (MCP routes can enforce EU-only data processing)
