Microsoft Teams SDK / Hacker News (70pts)·medium signal

Microsoft released the Teams SDK for building and deploying agents directly into Microsoft Teams, with support for Model Context Protocol (MCP) and Google's Agent-to-Agent (A2A) protocol. Available in JavaScript, C#, and Python (dev preview), the SDK treats Teams as just another adapter — your server infrastructure stays yours. Agents deploy across Teams, Outlook, and M365 Chat from a single codebase.
