update_page · Multi-MCPs MCP: Risk & Policy

WHAT IT DOES

What update_page does on Multi-MCPs

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

WHY IT NEEDS A POLICY

Why update_page needs a policy

The tool creates or modifies data in a reversible manner by updating Notion page properties. This is a classic Write operation. Severity is medium because inadvertent or malicious updates could modify important documentation or information in Notion workspaces, but the changes are not destructive (pages remain intact) and can be reverted.

From the tool's definition Tool name is 'update_page' and description states 'Update a Notion page properties' — this modifies existing data (Notion pages) reversibly through property updates.

Verdict

update_page Rate-limited

update_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.
