This is Microsoft's official MCP server for Word document operations, hosted on their Agent365 cloud infrastructure. It exposes tools for programmatic Word document manipulation through a streamable HTTP transport. You'll need a Microsoft tenant ID to connect to the remote endpoint. The source repository lives in Microsoft's EMU (Enterprise Managed User) GitHub organization, which requires SSO authentication to access, so documentation and implementation details aren't publicly visible. Reach for this when you're building AI workflows that need to create, modify, or extract content from Word documents within a Microsoft 365 environment, though you'll likely need to work with your enterprise admin to get proper access credentials and discover the full API surface.
