Continuing our journey of integrating AI agents into existing App Service applications - now with multi-agent architecture, MCP tools, .NET Aspire, and Premium v4.
Introduction: The Evolution of AI-Powered App Service Applications
Over the past few months, we've been exploring how to supercharge existing Azure App Service applications with AI capabilities. If you've been following along with this series, you've seen how we can quickly integrate AI Foundry agents with MCP servers and host remote MCP servers directly on App Service.
Today, we're taking the next leap forward by demonstrating how to build sophisticated multi-agent systems that leverage connected agents, Model Context Protocol (MCP), and OpenAPI tools - all running on Azure App Service's Premium v4 tier with .NET Aspire for enhanced observability and cloud-native development experience.

What Makes This Sample Special?
This fashion e-commerce demo showcases several cutting-edge technologies working together:
๐ค Multi-Agent Architecture with Connected Agents
Unlike single-agent systems, this sample implements an orchestration pattern where specialized agents work together:
- Main Orchestrator: Coordinates workflow and handles inventory queries via MCP tools
- Cart Manager: Specialized in shopping cart operations via OpenAPI tools
- Fashion Advisor: Provides expert styling recommendations
- Content Moderator: Ensures safe, professional interactions
๐ง Advanced Tool Integration
- MCP Tools: Real-time connection to external inventory systems using the Model Context Protocol
- OpenAPI Tools: Direct agent integration with your existing App Service APIs
- Connected Agent Tools: Seamless agent-to-agent communication with automatic orchestration
โก .NET Aspire Integration
- Enhanced development experience with built-in observability
- Simplified cloud-native application patterns
- Real-time monitoring and telemetry (when developing locally)
๐ Premium v4 App Service Tier
- Latest App Service performance capabilities
- Optimized for modern cloud-native workloads
- Enhanced scalability for AI-powered applications
Key Technical Innovations
Connected Agent Orchestration
Your application communicates with a single main agent, which automatically coordinates with specialist agents as needed. No changes to your existing App Service code required.
Dual Tool Integration
This sample demonstrates both MCP tools for external system connectivity and OpenAPI tools for direct API integration.
Zero-Infrastructure Overhead
Agents work directly with your existing App Service APIs and external endpoints - no additional infrastructure deployment needed.
Why These Technologies Matter for Real Applications
The combination of these technologies isn't just about showcasing the latest features - it's about solving real business challenges. Let's explore how each component contributes to building production-ready AI applications.
.NET Aspire: Enhancing the Development Experience
This sample leverages .NET Aspire to provide enhanced observability and simplified cloud-native development patterns. While .NET Aspire is still in preview on App Service, we encourage you to start exploring its capabilities and keep an eye out for future updates planned for later this year.
What's particularly exciting about Aspire is how it maintains the core principle we've emphasized throughout this series: making AI integration as simple as possible. You don't need to completely restructure your application to benefit from enhanced observability and modern development patterns.
Premium v4 App Service: Built for Modern AI Workloads
This sample is designed to run on Azure App Service Premium v4, which we recently announced is Generally Available. Premium v4 is the latest offering in the Azure App Service family, delivering enhanced performance, scalability, and cost efficiency.
From Concept to Implementation: Staying True to Our Core Promise
Throughout this blog series, we've consistently demonstrated that adding AI capabilities to existing applications doesn't require massive rewrites or complex architectural changes. This multi-agent sample continues that tradition - what might seem like a complex system is actually built using the same principles we've established:
โ
Incremental Enhancement: Build on your existing App Service infrastructure
โ
Simple Integration: Use familiar tools like azd up
for deployment
โ
Production-Ready: Leverage mature Azure services you already trust
โ
Future-Proof: Easy to extend as new capabilities become available
Looking Forward: What's Coming Next
This sample represents just the beginning of what's possible with AI-powered App Service applications. Here's what we're working on next:
๐ MCP Authentication Integration
Enhanced security patterns for production MCP server deployments, including Azure Entra ID integration.
๐ New Azure AI Foundry Features
As Azure AI Foundry continues to evolve, we'll be updating this sample to showcase:
- New agent capabilities
- Enhanced tool integrations
- Performance optimizations
- Additional model support
๐ Advanced Analytics and Monitoring
Deeper integration with Azure Monitor for:
- Agent performance analytics
- Business intelligence from agent interactions
๐ง Additional Programming Language Support
Following our multi-language MCP server samples, we'll be adding support for other languages in samples that will be added to the App Service documentation.
Getting Started Today
Ready to add multi-agent capabilities to your existing App Service application? The process follows the same streamlined approach we've used throughout this series.
Quick Overview
- Clone and Deploy: Use
azd up
for one-command infrastructure deployment - Create Your Agents: Run a Python setup script to configure the multi-agent system
- Connect Everything: Add one environment variable to link your agents
