This server connects to Microsoft Graph to pull organizational data about users in your tenant. It's designed for agents that need to understand reporting structures and team relationships within Microsoft 365. You'll reach for this when building tools that need to know who someone's manager is, who reports to them, or general user profile details from your directory. The streamable-http transport means it runs as a hosted service under Microsoft's Agent365 infrastructure rather than locally, and you'll need to authenticate against your specific tenant. If you're building AI assistants that need to navigate org charts or route requests based on team structure, this gives you those Graph API lookups without building your own integration.
