AI agents call get_memory_stats to retrieve information from Robust Long-Term Memory MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves statistical information about the memory system without modifying or deleting data. Read operations have low blast radius as they cannot cause data loss or unintended state changes. The empty description is a limitation, but the naming convention ('get_') and context of sibling tools (search_*, remember, update_memory, delete_memory) clearly establish this as a retrieval operation.
From the tool's definition Tool name 'get_memory_stats' indicates retrieval of statistics/metrics about memory system; sibling tools show this server performs memory operations, and 'get_*' prefixed tools consistently retrieve data without modification; empty description lowers…
Documented attack patterns abuse exactly the kind of access get_memory_stats gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Robust Long-Term Memory MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_memory_stats:
{
"version": "1",
"default": "deny",
"tools": {
"get_memory_stats": {}
}
}get_memory_stats is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_memory_stats. It is categorised as a Read tool in the Robust Long-Term Memory MCP MCP Server, which means it retrieves data without modifying state.
Register the Robust Long-Term Memory MCP server in PolicyLayer and add a rule for get_memory_stats: 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 Robust Long-Term Memory MCP. Nothing to install.
get_memory_stats 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 get_memory_stats 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 get_memory_stats. 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.
get_memory_stats is provided by the Robust Long-Term Memory MCP server (rotoslider/long-term-memory-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
