列出所有文件夹
AI agents call list_folders to retrieve information from Mi Note MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns a list of existing folders without modifying, deleting, or executing any operations. It is a pure read operation that retrieves data from Xiaomi Cloud Notes. The low severity reflects that listing folders poses minimal risk—an AI agent cannot cause harm by reading folder metadata.
From the tool's definition Tool name 'list_folders' and description '列出所有文件夹' (list all folders) indicate a retrieval operation with no side effects.
