Why CreateTokenWithIAM needs a policy

The name suggests creating an authentication token using IAM credentials, which could be a Write or Execute action. However, with no description available, it's unclear whether this creates a persistent resource, triggers external operations, or simply exchanges credentials for a token (which may be ephemeral). Lowering confidence significantly due to the empty description.

From the tool's definition Tool name: CreateTokenWithIAM — description is empty/uninformative

POLICY

How to control CreateTokenWithIAM

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

policy.json

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

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