Suggest reviewable memory operations from explicit conversation signals. Use this after
AI agents call memory_extract to retrieve information from Munin Memory without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears designed to query and surface memory-related information from conversation context for review purposes. It does not create, modify, delete, or execute operations—it merely extracts and suggests them to the user for approval/review. This is a read-class operation with low severity since it only retrieves data without side effects.
From the tool's definition Tool name is 'memory_extract' and description indicates it suggests/reviews memory operations based on conversation signals.
Attacks that exploit this kind of access
Suggest reviewable memory operations from explicit conversation signals. Use this after. It is categorised as a Read tool in the Munin Memory MCP Server, which means it retrieves data without modifying state.
Register the Munin Memory MCP server in PolicyLayer and add a rule for memory_extract: 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 Munin Memory. Nothing to install.
memory_extract 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 memory_extract 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 memory_extract. 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.
memory_extract is provided by the Munin Memory MCP server (magnus-gille/munin-memory). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
