Enables MCP-capable AI clients to use a 21Vianet-operated Microsoft 365 tenant on the user's behalf — reading mail, analyzing calendar conflicts, searching OneDrive and SharePoint files, and sending messages after confirmation — through a single Streamable HTTP endpoint with OAuth and delegated Microsoft Graph China permissions. Respects existing tenant roles, scopes, and audit boundaries, so access never exceeds what the signed-in user already has.
