Why calculate_route needs a policy

With an empty description, classification is uncertain. The name 'calculate_route' suggests a read-like computation (e.g., Amazon Location Service route calculation), which would be a Read operation with low severity. However, without description, confidence is low. Defaulting to Other due to insufficient information, though Read is the most likely true category.

From the tool's definition Tool name is 'calculate_route' but description is empty or uninformative. The name suggests a route calculation (likely a read/query operation), but no description is provided to confirm.

How to control calculate_route

PolicyLayer is an MCP gateway — it sits between your AI agents and AWS Labs Amazon Kendra Index MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for calculate_route:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "calculate_route": {
      "limits": [
        {
          "counter": "calculate_route_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

calculate_route gets a rate cap, and everything else on the server is denied unless you say otherwise.
