AI agents call search_memories to retrieve information from A-Modular-Kingdom without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name 'search_memories' indicates a query/retrieval function. Despite the lack of description, the semantic context—appearing alongside save/delete/query tools on a memory-management server—suggests this performs read-only searches of stored data with no side effects. The absence of verbs like 'delete', 'modify', or 'execute' further supports a Read classification.
From the tool's definition Tool name 'search_memories' strongly implies a read operation that queries memory without modification. The empty description prevents full certainty, but the naming convention aligns with non-destructive retrieval, consistent with sibling tools like…
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 A-Modular-Kingdom, 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 A-Modular-Kingdom MCP Server, which means it retrieves data without modifying state.
Register the A-Modular-Kingdom 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 A-Modular-Kingdom. 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 A-Modular-Kingdom MCP server (masihmoafi/a-modular-kingdom). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from A-Modular-Kingdom, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
