Lessons Learned: Building Multi-Agent Systems with Anthropic’s MCP & Pydantic AI

AI agent integration is transforming GenAI development, but standardization remains the missing piece. 🧩

In this talk, Maks Operlejn, Senior ML Engineer, explores how Model Context Protocol (MCP) and modern frameworks are reshaping how we build production-grade AI systems.

You’ll learn about:

  • Pydantic AI essentials – building type-safe, production-grade agents with structured outputs, dependency injection, and powerful evaluation tools,
  • MCP fundamentals – Anthropic’s open standard for connecting AI models to external data sources and tools,
  • Multi-agent system architecture – structuring data on demand with distributed, collaborative AI agents,
  • 10 lessons learned – mistakes and breakthroughs from building scalable agent systems,
  • Practical recommendations – best practices for creating secure, maintainable AI integrations.

If you’re building LLM-powered applications or exploring agentic AI workflows, this talk is your field guide to standardizing agent integration.
