Fetches asset folders from Storyblok space
AI agents call fetch-asset-folders to retrieve information from MCP Storyblok Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries asset folder metadata without causing side effects. It is purely informational and aligns with the Read category (search, list, get, fetch). The low severity reflects minimal blast radius if misused by an AI agent, as it only exposes folder structure information without write or destructive capabilities.
