THE RISK

Medium Risk

Why create_access_key needs a policy

Creating access keys is a reversible Write operation (keys can be deactivated/deleted), but carries high severity due to credential exposure risk if an AI agent generates keys without authorization or safeguards. The tool creates new authentication material that could be misused for unauthorized access to AWS resources.

From the tool's definition Tool name 'create_access_key' indicates creation of AWS access credentials, which modifies AWS account security posture. Description is empty, requiring inference from name.

POLICY

How to control create_access_key

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 create_access_key:

policy.json

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

create_access_key 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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
