List memories with optional filtering
AI agents call list_memories to retrieve information from SelfHub 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 or queries stored memory data with optional filtering. It performs no side effects, creation, modification, or deletion. However, the severity is medium rather than low because the tool accesses personal AI memory data which could be sensitive (conversations, personal preferences, private information), so misuse or unauthorized access could expose private user information to an AI agent.
From the tool's definition Tool name 'list_memories' and description 'List memories with optional filtering' indicate data retrieval without modification.
