Search across all memory for a term
AI agents call search_memory to retrieve information from Enhanced 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 or queries data from a memory store without side effects. It is a search/query function that returns matching results. No data is created, modified, deleted, or executed. The blast radius of misuse is minimal — an agent might retrieve sensitive information already stored in memory, but cannot alter state or perform actions outside the read scope.
From the tool's definition Tool name is 'search_memory' and description states 'Search across all memory for a term' — a query operation with no data modification, deletion, or execution of external commands.
Attacks that exploit this kind of access
Search across all memory for a term. It is categorised as a Read tool in the Enhanced MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Enhanced MCP Server MCP server in PolicyLayer and add a rule for search_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 Enhanced MCP Server. Nothing to install.
search_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 search_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 search_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.
search_memory is provided by the Enhanced MCP Server MCP server (pbulbule13/mcpwithgoogle). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
