Creativity · MCP — server

MCP OneDrive Server

The MCP OneDrive Server uses Microsoft Graph to expose OneDrive personal and OneDrive for Business as structured tools: list children, download content, upload bytes, search, and create sharing links. Auth uses Azure AD app registration with delegated or application permissions and respects Microsoft 365 sharing policies.

Frequently asked questions

Does it work with OneDrive for Business?

Yes — both OneDrive personal (Microsoft account) and OneDrive for Business (work/school account) are accessed through the same Microsoft Graph endpoints.

What permissions does the Azure AD app need?

At minimum Files.ReadWrite for the user's own drive. For multi-user scenarios use delegated permissions with offline_access for refresh tokens.

Can it open Office documents?

It downloads the raw bytes. For rendered content, pair it with the SharePoint or Microsoft Graph Search MCP servers that return extracted text.
