Why gateway_target_update needs a policy

The description is empty and uninformative, making it impossible to determine the exact behavior. The tool name suggests a write/update operation on a gateway target, but this is inconsistent with the Amazon Translate server context. Without further evidence, confidence is very low. Assigning 'Other' with medium severity to be cautious given the update semantics in the name.

From the tool's definition Tool name is 'gateway_target_update' but description is empty; name alone does not match the Amazon Translate server's stated functionality (translation, terminology management, batch processing).

POLICY

How to control gateway_target_update

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "gateway_target_update": {
      "limits": [
        {
          "counter": "gateway_target_update_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

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