Can AI agents automate SharePoint?

SharePoint's strongest documented automation path is PowerShell (best path: CLI). Microsoft maintains separate SharePoint Online and SharePoint Server modules that return structured objects for tenant, site, farm, service, application, and content administration; they are not one interchangeable command surface, and Server commands often require elevated farm access. API and Power Automate also score 8. CLI is the chosen path because farm and tenant administration remain PowerShell-specific and the Online versus Server split is explicit on the opened module indexes. Microsoft Graph gives stable read and write access to Online sites, lists, list items, document libraries, files, pages, permissions, and tenant settings, while native SharePoint REST exposes OData-style CRUD over a wider object model and also applies to supported Server versions. Online uses Microsoft identity platform delegated or application permissions; least-privilege site-scoped grants should replace tenant-wide rights where possible. SharePoint Server supports claims-based Windows, SAML, forms, and, in Subscription Edition, OIDC authentication. SharePoint Framework is the current client-side extension model; the older SharePoint Add-in model and Azure ACS authorization path are retired for Microsoft 365 and must not anchor new Online automation. Microsoft's first-party Power Automate connector is extensive for lists, libraries, files, approvals, permissions, forms, and triggers, including a smaller on-premises set through the data gateway. Native list and document-library webhooks remove polling but expire and carry only change signals, so clients must renew and reconcile changes. Version, tenant, site, sensitivity-label, retention, permission, and data residency boundaries remain load-bearing. A scored first-party MCP path and a repeatable computer-use result remain unassessed.
