根据关键词搜索笔记标题和摘要
AI agents call search_notes 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 searches and retrieves note metadata (titles and summaries) based on keywords. It has no side effects—it only reads and returns matching results. While the server includes destructive tools (delete_note, delete_folder) and write operations (create_note, update_note), this specific tool is purely informational retrieval, placing it in the Read category with low severity.
From the tool's definition Tool name 'search_notes' and description '根据关键词搜索笔记标题和摘要' (search notes by keyword in titles and summaries) indicate a query operation that retrieves data without modifying or executing operations.
