This tool searches the persistent memory layer for relevant information, preferences, and past context. It uses semantic matching to find connections between your query and stored memories, even when exact keywords don
AI agents call searchMCPMemory to retrieve information from MCP Memory without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
searchMCPMemory retrieves and queries stored data without side effects. It performs search operations only, returning matching memories based on semantic similarity. No data is created, modified, deleted, or executed. This is a straightforward Read category tool with low severity because even if misused by an agent, it only exposes information without causing irreversible harm.
From the tool's definition Tool description states it 'searches the persistent memory layer' and 'uses semantic matching to find connections' — pure information retrieval with no modification or deletion.
Attacks that exploit this kind of access
This tool searches the persistent memory layer for relevant information, preferences, and past context. It uses semantic matching to find connections between your query and stored memories, even when exact keywords don. It is categorised as a Read tool in the MCP Memory MCP Server, which means it retrieves data without modifying state.
Register the MCP Memory MCP server in PolicyLayer and add a rule for searchMCPMemory: 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 MCP Memory. Nothing to install.
searchMCPMemory 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 searchMCPMemory 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 searchMCPMemory. 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.
searchMCPMemory is provided by the MCP Memory MCP server (redaphid/mcp-memory). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
searchMCPMemory is one line of MCP Memory's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
