AI agents call search_memories to retrieve information from RememberMe without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool's name and context within a memory management system with semantic search capabilities indicate this performs data retrieval. Despite the empty description, the functional pattern of sibling tools and the server's stated search feature strongly suggest read-only semantics. No evidence of modification, deletion, execution, or financial impact.
From the tool's definition Tool name 'search_memories' indicates a query/search operation. The server description emphasizes 'semantic search' as a core function, and the sibling tools include add/delete/update/get_memory, suggesting this tool performs retrieval without modification.
Documented attack patterns abuse exactly the kind of access search_memories gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and RememberMe, and nothing reaches the server without passing your rules. This is the rule we recommend for search_memories:
{
"version": "1",
"default": "deny",
"tools": {
"search_memories": {}
}
}search_memories is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

search_memories. It is categorised as a Read tool in the RememberMe MCP Server, which means it retrieves data without modifying state.
Register the RememberMe MCP server in PolicyLayer and add a rule for search_memories: 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 RememberMe. Nothing to install.
search_memories 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_memories 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_memories. 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_memories is provided by the RememberMe MCP server (joexie/remember-me). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from RememberMe, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
