Teams is where human and agent collaboration happens

People collaborate together in Teams to get work done. Agents, AI-powered assistants that can automate tasks, are now collaborators in getting work done in Teams— across chats, meetings, channels, and business apps. Microsoft offers native agents like Facilitator, Interpreter, and Channel Agent, while also enabling developers and partners to bring third-party agents into Teams through the Agent Marketplace.

Teams is a high-engagement surface where agents can collaborate with users in the natural flow of work — without requiring users to switch applications or adopt entirely new experiences. By building agents for Teams, developers can tap into an enterprise-ready platform with identity, security, collaboration, meetings, and Microsoft 365 context already built in. This reduces development complexity, accelerates time-to-market, and drives stronger adoption by embedding agents directly into the places where customers already communicate, collaborate, and make decisions every day.

Microsoft Teams SDK

Teams SDK is the developer toolkit for building conversational agents and other app experiences in Teams. Generally available for C#, TypeScript and Python, you can use Teams SDK to bring existing agents to Teams or build brand new collaborative experiences. Bring agents to life in 1:1 chats with users, group chats and channels with conversational features like emoji reactions, targeted messages, @mentions, quoted and threaded replies, slash commands and dynamic prompt suggestions.

Latest developer tools

The Teams developer CLI, included with Teams SDK, streamlines app development with quickstart project templates and app lifecycle management tools. With the CLI, you can be using the real Teams client to chat with a starter agent running from code in your development environment in minutes.
