Embedding AI Intelligence into Enterprise Apps: Building AI Agents with NestJS and Claude

This practical guide demonstrates how to integrate AI capabilities directly into existing ERP systems without separate infrastructure. By building a custom tool-calling layer with Claude Haiku and leveraging generative UI components, developers can transform data queries into intelligent agent responses that render dynamic React components. This approach eliminates the need to maintain separate MCP servers while enabling both traditional API responses and AI-generated UI components.
