OSS AI Summit: Building with LangChain


Most AI demos look impressive in a notebook, but they fall apart the moment they touch real data, real users, or real scale. The companies that will win in 2026 aren’t the ones with the flashiest prototypes, they’re the ones who can reliably design, debug, and deploy agent-powered AI applications.

That’s exactly why we created the OSS AI Summit.

On December 10th we’re bringing together people from LangChain and Microsoft for a focused, no-fluff 2-hour online event centered on LangChain v1 and the patterns that turn experiments into production systems.

What you’ll walk away with

  • A clear mental model of LangChain v1: how components, agents, tools, and memory actually fit together in Python and JavaScript
  • Real-world war stories from teams running agents to solve real-world problems (including a candid fireside chat with people from Intercom)
  • Live walkthrough of MCP (Model Context Protocol) powering single and multi-agent systems with LangChain.js
  • Practical demos you can run today including agents that query databases, call APIs, and coordinate across specialized roles
  • A Q&A panel with Hunter Lovell and Sydney Runkle from LangChain

We’re sharing three complete reference apps so you can explore the concepts hands-on:

• AI Sales Analyst – Python agent that analyzes real sales data in PostgreSQL using LangChain + Azure OpenAI + MCP

https://github.com/Azure-Samples/langchain-agent-python

• AI Travel Agency – Multi-agent system in LangChain.js with MCP servers in Python, Node.js, Java, and .NET, deployed on Azure Container Apps

https://github.com/Azure-Samples/ai-travel-agents

• Serverless Burger-Order Agent – End-to-end LangChain.js agent using MCP to place orders via a real API, running on Azure Static Web Apps + Azure Functions

https://github.com/Azure-Samples/mcp-agent-langchainjs

Who this is for

  • Developers moving from simple chatbots to agentic workflows
  • Architects figuring out how to connect LLMs to internal systems securely
  • Engineering leads who need proven patterns for reliability, observability, and scale on Azure
