AI agents call search to retrieve information from Memoraeu without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation that retrieves or searches through stored memories using natural language. It has no side effects on the data—it does not create, modify, delete, or execute external operations. The search capability presents minimal security risk as it only returns information already accessible to the user within their own encrypted memory store.
From the tool's definition Tool name 'search' combined with description 'Search memories by natural language query' indicates a retrieval operation that queries existing data without modification or deletion.
Attacks that exploit this kind of access
Search memories by natural language query. It is categorised as a Read tool in the Memoraeu MCP Server, which means it retrieves data without modifying state.
Register the Memoraeu MCP server in PolicyLayer and add a rule for search: 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 Memoraeu. Nothing to install.
search 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 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. 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 is provided by the Memoraeu MCP server (pquattro/memoraeu-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
