This is Microsoft's official remote MCP server for accessing OneDrive and SharePoint through their Agent365 cloud service. It runs as a hosted endpoint rather than a local process, which means you authenticate once through your Microsoft tenant and can then query files, folders, and documents across your organization's SharePoint sites and OneDrive accounts. The streamable HTTP transport suggests it handles file operations efficiently without loading everything into memory. You'd reach for this when building agents that need to search company documentation, retrieve specific files, or work with collaborative documents stored in Microsoft 365. Note that it requires tenant-level configuration and routes through Microsoft's enterprise infrastructure, so this is aimed at organizations already invested in the Microsoft 365 ecosystem.
