Search and retrieve relevant short-term memories based on recent conversation context. Returns top relevant, next relevant, and random flashback memories.
AI agents call search_short_term_memories to retrieve information from Memory 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 memory data without creating, modifying, or deleting anything. It performs a query operation with no side effects, fitting the Read category. Severity is low because even if an agent misuses retrieval, it only accesses existing data without affecting system integrity or data state.
From the tool's definition Tool description states 'Search and retrieve relevant short-term memories' with no modifications, deletions, or state changes. The verb 'retrieve' and 'returns' confirm read-only operation.
