search_memos
AI agents call search_memos to retrieve information from Memos MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Search operations retrieve and query data without side effects. While the tool description is empty, the explicit mention of 'searching' in the server overview and the tool's name ('search_memos') provide strong evidence this is a Read category tool.
From the tool's definition Tool name 'search_memos' indicates a query/search operation. Server description states tool enables 'searching' memos. No description provided for this specific tool, but the name and server context clearly indicate data retrieval without modification.
