Retrieve relevant memories based on context
AI agents call retrieve_memory to retrieve information from memU MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves stored memory data based on contextual input. It has no side effects—it does not create, modify, delete, execute code, or move money. The action is read-only, making it the lowest risk category. Confidence is high because the name and description clearly indicate retrieval/query semantics typical of Read operations.
From the tool's definition Tool name 'retrieve_memory' with description 'Retrieve relevant memories based on context' performs data retrieval without modification or deletion.
Attacks that exploit this kind of access
Retrieve relevant memories based on context. It is categorised as a Read tool in the memU MCP Server MCP Server, which means it retrieves data without modifying state.
Register the memU MCP Server MCP server in PolicyLayer and add a rule for retrieve_memory: 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 memU MCP Server. Nothing to install.
retrieve_memory 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 retrieve_memory 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 retrieve_memory. 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.
retrieve_memory is provided by the memU MCP Server MCP server (monsterone1/memu-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
retrieve_memory is one line of memU MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
