Get a unique list of all article folders to understand the knowledge repository structure
AI agents call listFolders to retrieve information from Article Manager MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool only retrieves and lists existing folder metadata without creating, modifying, deleting, or executing any operations. It has minimal blast radius—an AI agent calling this repeatedly poses no meaningful security risk beyond potential information disclosure of folder structure, which is typically low-sensitivity metadata.
From the tool's definition Tool name is 'listFolders' and description states it 'Get[s] a unique list of all article folders to understand the knowledge repository structure'. This is a pure read/query operation with no side effects.
