THE RISK

Why StartAHORun needs a policy

The tool initiates a run/operation in an EKS-related system (AHO likely refers to an AWS service like Analysis or Operational tooling). While the description is empty, the 'Start' prefix and 'Run' suffix strongly indicate execution of external operations whose effects depend on parameters.

From the tool's definition Tool name 'StartAHORun' suggests launching or initiating an operation within AWS EKS context. The 'Start' verb indicates triggering execution of a process.

Documented attack patterns abuse exactly the kind of access StartAHORun gives an agent:

POLICY

How to control StartAHORun

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 StartAHORun:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "StartAHORun": {
      "limits": [
        {
          "counter": "startahorun_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

StartAHORun stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Amazon EKS MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

What risk level is StartAHORun? +

StartAHORun is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit StartAHORun? +

Yes. Add a rate_limit block to the StartAHORun 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 StartAHORun completely? +

Set action: deny in the PolicyLayer policy for StartAHORun. 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 StartAHORun? +

StartAHORun 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.
