THE RISK

Medium Risk

Why create_data_processing_role needs a policy

The tool creates an IAM role, which is a Write action (creates data/configuration). While reversible (roles can be deleted), it has high severity because misconfigured roles grant permissions that could enable further attacks. Empty description lowers confidence slightly, but the name clearly indicates role creation within an EKS management context.

From the tool's definition Tool name 'create_data_processing_role' indicates creation of an IAM role. Sibling tools include 'add_inline_policy' and 'add_user_to_group', confirming this server manages IAM/identity operations. Creating roles is a reversible Write operation.

POLICY

How to control create_data_processing_role

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

policy.json

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

create_data_processing_role 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.

FAQ

Questions about create_data_processing_role

What does the create_data_processing_role tool do? +

create_data_processing_role. It is categorised as a Write tool in the Amazon EKS MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_data_processing_role? +

Register the Amazon EKS MCP Server MCP server in PolicyLayer and add a rule for create_data_processing_role: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Amazon EKS MCP Server. Nothing to install.

What risk level is create_data_processing_role? +

create_data_processing_role is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_data_processing_role? +

Yes. Add a rate_limit block to the create_data_processing_role rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block create_data_processing_role completely? +

Set action: deny in the PolicyLayer policy for create_data_processing_role. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides create_data_processing_role? +

create_data_processing_role is provided by the Amazon EKS MCP Server MCP server (awslabs.eks-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Amazon EKS MCP Server tool call.

Start from Amazon EKS MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
