🔍 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
