get_folder_children
AI agents call get_folder_children to retrieve information from Looker MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool appears to retrieve folder hierarchy or contents from Looker's content management system without modifying, deleting, or executing operations. The 'get' prefix and 'children' reference (suggesting a query for child items) are consistent with Read category operations.
