WHAT IT DOES

What restore-story does on MCP Storyblok Server

WHY IT NEEDS A POLICY

Why restore-story needs a policy

Restoring a story to a previous version is a Write operation—it modifies the current state of a story. Although it can be undone by restoring to another version, the action itself overwrites the current version's content. This is less severe than Destructive (which would be irreversible deletion) and more than Read.

From the tool's definition Tool name 'restore-story' and description 'Restores a story to a specific version' indicate reverting content to a prior state, which modifies data but remains reversible via another restore operation.
