Integrating AI Agents with Web Apps Using the Model Context Protocol (MCP)

Central Theme: Multi-Agent AI Integration

The video demonstrates how to create sophisticated, “multi-agent” workflows by connecting an AI assistant like Claude to multiple, independent web services using the Model Context Protocol (MCP). The core idea is to move beyond a simple AI chatbot on a single website and enable an AI to orchestrate tasks across different systems on a user’s behalf.

Key Arguments & Demonstration

The presentation uses a demo involving a fictional e-commerce site (“Yam’s Cheesesteaks”) and an HR data service to illustrate the concept:

  • Single-Agent AI: First, the AI (Claude) is connected to the e-commerce site’s API via an MCP server. This allows the AI to perform actions for the authenticated user, such as getting the menu and adding items to the cart.
  • Multi-Agent Workflow: The true power is shown by introducing a second, separate service—an “HR server” with employee food preferences. The AI connects to both the e-commerce server and the HR server simultaneously.
  • Agentic Task: The AI is asked to order lunch for a group. It first queries the HR server to retrieve food preferences and then uses that information to place a customized order on the e-commerce site. This showcases an “agentic workflow” where the AI gathers data from one source to take action on another.

Technical Implementation Highlights

  • Authentication Bridge: The system securely bridges the web user’s identity (managed by Clerk) to the AI agent. It uses a .well-known/oauth-protected-resource endpoint to inform the MCP client how to handle authentication, ensuring the AI acts with the correct permissions.
  • Real-Time UI Updates: When the AI adds an item to the cart, the web interface updates instantly without a page refresh. This is achieved using Server-Sent Events (SSE), where the client maintains a live connection to the server, which pushes any cart updates in real-time.

Conclusion & Takeaways

While MCP for HTTP is still an evolving standard, it enables powerful and flexible AI-driven automation. This approach allows an AI to act as a central orchestrator, connecting disparate services to automate complex tasks. This is a significant step beyond simple, embedded chatbots and points toward a future of more capable, integrated AI agents.

Mentoring Question

What multi-system workflows in your own projects or daily tasks could be automated by an AI agent that can access and act upon different data sources?
