Retrieve the full content of a single memory entry by its UUID. Use this after
AI agents call memory_get 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 retrieves stored memory data by identifier without modifying, deleting, or executing operations. This is a straightforward read operation. Severity is low because retrieving stored context poses minimal risk—the blast radius of misuse is limited to information disclosure of the agent's own stored memory.
From the tool's definition Tool name 'memory_get' and description 'Retrieve the full content of a single memory entry by its UUID' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
Retrieve the full content of a single memory entry by its UUID. 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_get: 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_get 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_get 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_get. 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_get 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.
