What age_calculator does on SmartTools
AI agents invoke age_calculator to trigger actions in SmartTools. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
| Parameter | Type | Required | Description |
|---|---|---|---|
locale | string | — | Language for the source_url link (default en) |
at_date | string | — | Reference date, YYYY-MM-DD (default: today) |
birth_date | string | Yes | Date of birth, YYYY-MM-DD |
Parameters from the server's own tool schema.
Why age_calculator is rated High
age_calculator triggers real processes with real consequences. An agent gone sideways doesn't fire it once. It starts dozens of builds, sends mass notifications, or burns through compute before anyone looks up.
Attacks that exploit this kind of access
The rule that runs age_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 age_calculator, this is the rule to start with:
age_calculator stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. 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 age_calculator call is checked against it from then on.
