## Why mortgage_calculator is rated Low

This tool performs financial calculations and returns computed results (monthly payments, total interest, amortization schedule). It does not move money, commit financial obligations, or have any side effects — it is purely a read/compute operation similar to a calculator.

From the tool's own definition: "Calculate monthly mortgage payments, total interest, and amortization"

## Use case

AI agents call mortgage_calculator to retrieve information from GadgetHumans API Hub without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches GadgetHumans API Hub:

```json

  "tools": {
    "mortgage_calculator": {}
  }
}
```
