AI agents call list_memories to retrieve information from Memoraeu without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns stored memory data without modifying, deleting, or executing any operations. It is purely informational, allowing users to view their stored memories. The blast radius of misuse is minimal—an agent could retrieve memory contents but cannot modify or destroy them.
From the tool's definition Tool name 'list_memories' and description 'Liste les mémoires récentes' (List recent memories) indicate a retrieval operation with no side effects. The verb 'list' is explicitly a Read operation.

list_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 list_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 list_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.
