Retrieve a memory by ID
AI agents call get_memory to retrieve information from Memory MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves stored memories by identifier without side effects. It is a simple data retrieval operation analogous to a GET request or SELECT query. No data is created, modified, deleted, or executed. The low severity reflects minimal blast radius—misuse would only expose already-stored data readable by the authenticated user.
From the tool's definition Tool name 'get_memory' with description 'Retrieve a memory by ID' indicates a query operation that fetches existing data without modification.
Attacks that exploit this kind of access
Retrieve a memory by ID. It is categorised as a Read tool in the Memory MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Memory MCP Server MCP server in PolicyLayer and add a rule for get_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 Memory MCP Server. Nothing to install.
get_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 get_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 get_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.
get_memory is provided by the Memory MCP Server MCP server (nareshtt/mcp-memory-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
