duplicate_page · Notion MCP: Risk & Policy

WHAT IT DOES

What duplicate_page does on Notion

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

WHY IT NEEDS A POLICY

Why duplicate_page needs a policy

The tool creates new data (a page duplicate) in the Notion workspace without deleting the original, making it a Write operation. While reversible (the duplicate can be deleted), it modifies the workspace state by adding new content. Severity is medium because duplicating pages could clutter workspaces or create unintended copies if misused by an agent, but the impact is containable through deletion of the duplicate.

From the tool's definition duplicate_page creates a copy of a page with the same content in Notion workspace, which is a reversible modification operation

Verdict

duplicate_page Rate-limited

duplicate_page stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
