Microsoft and Anthropic jointly present how to build enterprise AI agents using Claude models (Opus, Sonnet, Haiku) within Microsoft Foundry. The webinar covers the Claude Agent SDK, which provides a production-ready agentic loop with built-in tools (code execution, file system, web search, MCP integration), context management, memory, permissions, and observability. A live demo shows a cupcake ordering agent built with Claude Sonnet via MCP, and a customer support intelligence agent using the Claude Agent SDK running as a hosted agent in Foundry. Key topics include model selection guidance (Sonnet as default, Opus for complex reasoning, Haiku for high-throughput tasks), agent evaluation pillars (quality, risk/safety, agentic task adherence), and enterprise governance via Microsoft Entra, Purview, and Defender.
