# Microsoft 365 Agents SDK

The Microsoft 365 Agents SDK lets developers build agents once and deploy them across channels such as Microsoft 365 Copilot, Microsoft Teams, and custom web apps, using whichever AI services or models they choose, with separate client libraries for C#, JavaScript and Python.

The Microsoft 365 Agents SDK gives developers scaffolding to build an agent's container, handling state, storage and the management of activities and events, then deploy that same agent across channels such as Microsoft 365 Copilot, Microsoft Teams, and custom web and other apps. A Microsoft 365 Copilot subscription is not required to use the SDK unless a project specifically targets that channel.

The SDK is agnostic about which AI services or models a developer uses to implement agentic patterns, and lets an agent be customized to match the specific behavior of a client such as Teams. Client libraries for C#/.NET, JavaScript and Python live in their own per-language repositories, with this repository acting as the general entry point and home for cross-cutting issues, and it also provides AI coding-assistant plugins with deep knowledge of the SDK's APIs.
