Microsoft (Client Credentials)

The Microsoft OAuth2 Client Credentials flow enables secure service-to-service authentication with Microsoft services without requiring user interaction. This server-to-server authentication method allows applications to authenticate using their own credentials via the Microsoft identity platform.

AI agents can use this integration to programmatically access Microsoft Graph APIs and other Microsoft cloud services, enabling automation of tasks like managing organizational data, calendar operations, email sending, and file management in a secure, scalable manner.
