Search through stored memories using keywords or tags. Returns relevant memories that match the search criteria.
AI agents call search_memories to retrieve information from AI Memory MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
search_memories queries and retrieves data based on search parameters but does not create, modify, or delete any memories. It has no side effects beyond returning matching results. This is a classic Read operation with minimal blast radius if misused—an agent could retrieve unintended memories but cannot harm data integrity or system state.
From the tool's definition Tool description states it 'Search through stored memories using keywords or tags. Returns relevant memories that match the search criteria.' The verb 'search' and 'returns' indicate data retrieval with no modification.
Attacks that exploit this kind of access
Search through stored memories using keywords or tags. Returns relevant memories that match the search criteria. It is categorised as a Read tool in the AI Memory MCP Server MCP Server, which means it retrieves data without modifying state.
Register the AI Memory MCP Server MCP server in PolicyLayer and add a rule for search_memories: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches AI Memory MCP Server. Nothing to install.
search_memories is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the search_memories rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for search_memories. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
search_memories is provided by the AI Memory MCP Server MCP server (scofieldkoh/mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
