Get the most recent memos.
AI agents call list_recent_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.
This tool retrieves existing memo data without side effects. It performs a read-only query to list memos ordered by recency. There is no data creation, modification, deletion, code execution, or financial impact. The blast radius of misuse is minimal—an agent could only exfiltrate memo contents that already exist, not cause irreversible harm or execute arbitrary operations.
From the tool's definition Tool name 'list_recent_memos' and description 'Get the most recent memos' indicate a query/retrieval operation with no modification or deletion of data.
