unfavorite_page · Collectives MCP: Risk & Policy

WHAT IT DOES

What unfavorite_page does on Collectives

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

WHY IT NEEDS A POLICY

Why unfavorite_page needs a policy

Unfavoriting a page removes a user preference/association but does not delete the page itself. This is a reversible modification to user data (favorites list), making it a Write operation. The blast radius is low since it only affects the current user's favorites and can be easily reversed by re-favoriting.

From the tool's definition 'unfavorite_page' and 'Remove a page from the authenticated user' — removes a favorite/bookmark association

unfavorite_page Rate-limited

unfavorite_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.
