WHAT IT DOES

What create_view does on SharePoint MCP Server

AI agents use create_view to create or update resources in SharePoint MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your SharePoint MCP Server environment.

WHY IT NEEDS A POLICY

Why create_view needs a policy

The tool creates a new view (a reversible configuration change) on a SharePoint list or library. This is a Write operation: it modifies the schema/structure of SharePoint resources by adding a view, but the operation is reversible (the view can be deleted). It does not execute arbitrary code, delete data irreversibly, or move money.

From the tool's definition create_view" tool that "Create[s] a new view for a list or library" — this is a create operation that adds a new view configuration to SharePoint.
