How Foundry integrates with open-source frameworks and tools | DEM333
Foundry lets agents built with open-source frameworks deploy to production without rewriting, using OpenAI-compatible APIs and MCP.
“Changing the model target is configuration not a rewrite.”
A Microsoft Build session (DEM333) demonstrates building an open-source agent with LangChain/LangGraph and MCP, then deploying it to Microsoft Foundry for production. The pitch is that Foundry's OpenAI-compatible APIs let developers swap model targets via configuration rather than rewriting code. It signals Microsoft's positioning of Foundry as an open-framework-friendly production layer for agents.
