What confidence_interval does on Gateway
AI agents call confidence_interval 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 |
|---|---|---|---|
n | integer | — | Sample size |
mean | number | — | Sample mean (mean mode) |
mode | string | — | mean or proportion |
std_dev | number | — | Sample standard deviation (mean mode) |
successes | integer | — | Successes (proportion mode) |
confidence | number | — | Confidence level 0..1 (default 0.95) |
Parameters from the server's own tool schema.
Why confidence_interval is rated Low
This is a pure mathematical calculator that performs statistical computations (confidence intervals for means/proportions). It takes input data and returns calculated results without modifying, creating, deleting, or executing external operations. No financial transactions, code execution, or irreversible actions are involved.
From the tool's definition Tool is a 'Confidence Interval Calculator' that computes statistical measures given sample statistics. The description indicates it retrieves or calculates mathematical outputs based on input parameters with no side effects on data or systems.
Attacks that exploit this kind of access
The rule that runs confidence_interval 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 confidence_interval, this is the rule to start with:
confidence_interval 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 confidence_interval call is checked against it from then on.
Questions about confidence_interval
Confidence Interval Calculator — Confidence interval for a population mean or proportion given sample statistics. It is categorised as a Read tool in the Gateway MCP Server, which means it retrieves data without modifying state.
confidence_interval accepts 6 parameters: n, mean, mode, std_dev, successes, confidence. 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 confidence_interval: 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.
confidence_interval 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 confidence_interval 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 confidence_interval. 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.
confidence_interval 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.
