Retrieve a specific memory by its ID
AI agents call get_memory to retrieve information from Claude Memory Server 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 a straightforward read operation analogous to a database fetch by primary key. Severity is low because retrieving stored memories has minimal blast radius even if misused by an AI agent—it cannot modify state, execute code, or cause financial transactions.
From the tool's definition Tool description states 'Retrieve a specific memory by its ID' - retrieval operation with no side effects. The verb 'Retrieve' and the read-only nature of fetching an existing memory by identifier confirm this is a data retrieval action.
Attacks that exploit this kind of access
Retrieve a specific memory by its ID. It is categorised as a Read tool in the Claude Memory Server MCP Server, which means it retrieves data without modifying state.
Register the Claude Memory 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 Claude Memory 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 Claude Memory Server MCP server (xiy/claude-memory-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
