What statistics does on Gateway
AI agents call statistics to retrieve information from Gateway without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
sample | boolean | — | Use sample (n-1) variance/stddev instead of population |
numbers | array | Yes | Array of numbers |
Parameters from the server's own tool schema.
Why statistics is rated Low
This is a computational utility that analyzes numerical data and returns statistical summaries. No data is created, modified, deleted, or executed. The tool has no external effects beyond returning calculated results. It poses minimal risk if misused by an AI agent, as it can only process and return statistics from input numbers.
From the tool's definition Tool performs purely analytical operations: 'Descriptive Statistics Calculator — Mean, median, min/max, range, variance and standard deviation of a number list.' These are read-only mathematical computations over provided data with no side effects, data…
Attacks that exploit this kind of access
The rule that runs statistics safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Gateway, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For statistics, this is the rule to start with:
statistics is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Gateway, apply this rule, and every statistics call is checked against it from then on.
Questions about statistics
Descriptive Statistics Calculator — Mean, median, min/max, range, variance and standard deviation of a number list. It is categorised as a Read tool in the Gateway MCP Server, which means it retrieves data without modifying state.
statistics accepts 2 parameters: sample, numbers. Required: numbers. The full parameter table on this page comes from the server's own tool schema.
Register the Gateway MCP server in PolicyLayer and add a rule for 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 Gateway. Nothing to install.
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 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 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.
statistics is provided by the Gateway MCP server (https://wingmanprotocol.com/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
