## 🔍 Mock Data Status

### Identified Mock Locations
1. `MultiModalProcessor.ts` - Image/audio/video embeddings (placeholder)
2. `llmService.ts` - Fallback mock responses
3. `MCPPowerPointBackend.ts` - Mock MCP client
4. `agentController.ts` - Mock agent responses
5. `toolHandlers.ts` - Mock status returns

### Action Required
⚠️ **These need real implementations before production deployment**

Recommendations:
- MultiModal: Integrate actual CLIP/Wav2Vec models
- LLM: Ensure API keys configured, remove fallback
- MCP: Connect to real MCP server
- Agents: Implement actual agent logic
- Tools: Connect to real data sources

---
