AI agents call statistics_analyzer to retrieve information from Math MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Statistics analysis typically retrieves, processes, and computes summary metrics from data without side effects. While the tool description is empty (reducing confidence), the server's mathematical computation context and the naming pattern of sibling tools suggest this is a read-only analytical tool.
From the tool's definition Tool name 'statistics_analyzer' indicates data analysis functionality. Server context describes 'mathematical computation tools' with 'statistics' as one topic area.
Documented attack patterns abuse exactly the kind of access statistics_analyzer gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Math MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for statistics_analyzer:
{
"version": "1",
"default": "deny",
"tools": {
"statistics_analyzer": {}
}
}statistics_analyzer is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
statistics_analyzer. It is categorised as a Read tool in the Math MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Math MCP Server MCP server in PolicyLayer and add a rule for statistics_analyzer: 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 Math MCP Server. Nothing to install.
statistics_analyzer 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 statistics_analyzer 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 statistics_analyzer. 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.
statistics_analyzer is provided by the Math MCP Server MCP server (111-test-111/math-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Math MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
