Why gateway_target_create needs a policy

The tool creates (Write category) a new gateway target, likely an AWS resource such as a load balancer target or network gateway endpoint. This is reversible via deletion, distinguishing it from Destructive actions. High severity reflects the potential blast radius: misconfigured gateway targets could redirect traffic, expose services, or disrupt cluster networking.

From the tool's definition Tool name 'gateway_target_create' indicates creation of a gateway target resource in AWS EKS context. The 'create' verb signifies a reversible write operation that establishes new infrastructure. No description provided, limiting certainty.

POLICY

How to control gateway_target_create

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 gateway_target_create:

policy.json

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

gateway_target_create 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 gateway_target_create

What does the gateway_target_create tool do? +

gateway_target_create. 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 gateway_target_create? +

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 gateway_target_create? +

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

Can I rate-limit gateway_target_create? +

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

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