revert_post · Blogger MCP: Risk & Policy

WHAT IT DOES

What revert_post does on Blogger

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

WHY IT NEEDS A POLICY

Why revert_post needs a policy

This tool modifies post state reversibly (published → draft). It does not delete data (would be Destructive), nor does it execute arbitrary code (would be Execute). The change is reversible—the post content remains intact and can be re-published. Severity is medium because reverting a post could disrupt published content availability or audience expectations, but the action is undoable.

From the tool's definition Tool description states 'Revert a published post back to draft' — changes post state from published to draft, modifying metadata/status without deleting content.
