What standard_deviation_calculator does on SmartTools
AI agents call standard_deviation_calculator to retrieve information from SmartTools 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 |
|---|---|---|---|
locale | string | — | Language for the source_url link (default en) |
values | array | Yes | The data set (at least 2 numbers) |
Parameters from the server's own tool schema.
Why standard_deviation_calculator is rated Low
Even though standard_deviation_calculator only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
The rule that runs standard_deviation_calculator safely
PolicyLayer is an MCP gateway: it sits between your AI agents and SmartTools, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For standard_deviation_calculator, this is the rule to start with:
standard_deviation_calculator 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 SmartTools, apply this rule, and every standard_deviation_calculator call is checked against it from then on.
