List stored memories, optionally filtered by category.
AI agents call list_memories to retrieve information from SAE4U Memory without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates stored memories without creating, modifying, deleting, or executing any operations. It is a pure read operation with minimal blast radius—an agent listing memories cannot cause harm beyond information disclosure of whatever memories have been previously stored. The filtering is a query parameter, not a destructive action.
From the tool's definition Tool name 'list_memories' and description 'List stored memories, optionally filtered by category' indicate a retrieval/query operation with no data modification.
Attacks that exploit this kind of access
List stored memories, optionally filtered by category. It is categorised as a Read tool in the SAE4U Memory MCP Server, which means it retrieves data without modifying state.
Register the SAE4U Memory MCP server in PolicyLayer and add a rule for list_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 SAE4U Memory. Nothing to install.
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.
list_memories is provided by the SAE4U Memory MCP server (simple4uhq/sae4u-memory). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
