AI agents call memory_statistics to retrieve information from MCP Mathematics without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about memory usage without side effects. It falls under the Read category as it queries and returns data (memory statistics) without creating, modifying, deleting, or executing operations. The severity is low because obtaining memory statistics poses minimal security risk even if misused by an AI agent.
From the tool's definition Tool name 'memory_statistics' and description 'Get memory statistics' indicate a read-only query of system or session memory metrics with no data modification, execution, or destructive capabilities.
Documented attack patterns abuse exactly the kind of access memory_statistics gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Mathematics, and nothing reaches the server without passing your rules. This is the rule we recommend for memory_statistics:
{
"version": "1",
"default": "deny",
"tools": {
"memory_statistics": {}
}
}memory_statistics is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get memory statistics. It is categorised as a Read tool in the MCP Mathematics MCP Server, which means it retrieves data without modifying state.
Register the MCP Mathematics MCP server in PolicyLayer and add a rule for memory_statistics: 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 MCP Mathematics. Nothing to install.
memory_statistics 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 memory_statistics 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 memory_statistics. 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.
memory_statistics is provided by the MCP Mathematics MCP server (shsharkar/mcp-mathematics). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MCP Mathematics, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
