set_page_tags · Collectives MCP: Risk & Policy

WHAT IT DOES

What set_page_tags does on Collectives

AI agents use set_page_tags 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 set_page_tags needs a policy

This tool modifies page attributes (tags) but does not delete, destroy, or execute arbitrary operations. The change is reversible—tags can be replaced again with different values. While it does alter data, the scope is limited to tag associations on a page, making it a Write operation.

From the tool's definition Tool description states 'Replace the tags on a page', which modifies page metadata. The term 'Replace' indicates reversible alteration of existing tags, not deletion of the page itself. Tag assignment is a standard write operation.
