get_user · Amazon EKS MCP Server MCP: Risk & Policy

WHAT IT DOES

What get_user does on Amazon EKS MCP Server

AI agents call get_user to retrieve information from Amazon EKS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why get_user needs a policy

The tool name 'get_user' indicates a query/retrieval operation that retrieves user data without side effects. However, confidence is reduced to 0.7 because the description is empty, preventing full assessment of scope (e.g., whether it returns sensitive credentials or is restricted by IAM).

From the tool's definition Tool name 'get_user' with empty description suggests a retrieval operation for user information. No write, delete, or execute keywords present.

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

POLICY

How to control get_user

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 get_user:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_user": {}
  }
}

get_user is read-only, so it stays allowed — but 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.
