This connects Claude to your Microsoft 365 tenant through the Agent365 service, letting you search across emails, SharePoint sites, OneDrive files, Teams chats, and other M365 content from a single interface. You'll need a tenant ID to configure the remote endpoint. Reach for this when you want Claude to pull information from your organization's scattered M365 data without switching between Outlook, Teams, and SharePoint. It uses streamable HTTP transport, so responses can start flowing before the full search completes. Note that the source repository appears to require Microsoft EMU authentication, suggesting this is intended for enterprise Microsoft customers with existing agent infrastructure.
