What insert does on Amazon EKS MCP Server

AI agents use insert to create or update resources in Amazon EKS MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Amazon EKS MCP Server environment.

Why insert needs a policy

In database and data management contexts, 'insert' creates new records or adds data. Within an AWS EKS server, this likely creates or adds entries to EKS-related resources (e.g., configurations, records, or metadata). This is reversible (can be updated/deleted later), making it Write rather than Destructive. Medium severity reflects potential for unintended data creation in a Kubernetes management context.

From the tool's definition Tool name 'insert' combined with EKS context suggests data creation/modification. Description is empty, limiting certainty.

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

How to control insert

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 insert:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "insert": {
      "limits": [
        {
          "counter": "insert_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

insert 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.

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

How do I enforce a policy on insert? +

Register the Amazon EKS MCP Server MCP server in PolicyLayer and add a rule for insert: 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 insert? +

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

Can I rate-limit insert? +

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

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

insert 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.
