Why copy_image_set needs a policy

The tool name suggests it creates a duplicate of an image set, which is a write operation that modifies state by creating new data. However, the empty description and incongruity with the stated server purpose (Amazon Translate for text translation) creates uncertainty.

From the tool's definition Tool name 'copy_image_set' combined with sibling tools like 'add_attachments_to_set' and 'add_communication_to_case' suggests data creation/modification operations.

POLICY

How to control copy_image_set

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 copy_image_set:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "copy_image_set": {
      "limits": [
        {
          "counter": "copy_image_set_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

copy_image_set stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Point your MCP client (Claude, Cursor, anything) at your gateway URL.
