create_page

What create_page does on Ncp

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

Why create_page is rated Medium

This tool creates a new page, which is a Write operation (creates/modifies data reversibly). It is not Destructive because page creation can be undone by deletion. Severity is medium because unauthorized page creation could lead to cluttered workspaces, information disclosure if sensitive pages are created, or resource exhaustion, but the blast radius is limited compared to destructive or financial operations.

From the tool's definition Tool description states 'Create a new page in Notion workspace' - the verb 'create' and 'new page' explicitly indicate a reversible write operation that modifies the workspace by adding a resource.
