Fetch details of a specific asset folder by its ID.
AI agents call fetch_asset_folder to retrieve information from Storyblok MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about an asset folder without creating, modifying, deleting, or executing any operations. It has no side effects and poses minimal security risk even if misused by an AI agent, as it only returns existing folder information.
From the tool's definition Tool name 'fetch_asset_folder' and description 'Fetch details of a specific asset folder by its ID' indicate a retrieval operation with no modification or deletion. The verb 'fetch' and the focus on 'details' confirm this is a read-only query.
