AI agents call policy_list 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.
Based on naming convention, 'policy_list' most likely queries or retrieves a list of IAM policies in an AWS/EKS context. This is a read-only retrieval operation with no side effects. However, confidence is not higher due to the empty description, which prevents direct confirmation.
From the tool's definition Tool name 'policy_list' with no description; pattern consistent with sibling tools like 'add_user_to_group' and 'add_inline_policy' on an AWS/EKS management server. The 'list' operation typically retrieves data without modification.
Documented attack patterns abuse exactly the kind of access policy_list gives an agent:
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 policy_list:
{
"version": "1",
"default": "deny",
"tools": {
"policy_list": {}
}
}policy_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

policy_list. It is categorised as a Read tool in the Amazon EKS MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Amazon EKS MCP Server MCP server in PolicyLayer and add a rule for policy_list: 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.
policy_list is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the policy_list 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.
Set action: deny in the PolicyLayer policy for policy_list. 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.
policy_list 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.
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.
