gateway_list · Amazon EKS MCP Server MCP: Risk & Policy

WHAT IT DOES

What gateway_list does on Amazon EKS MCP Server

AI agents call gateway_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.

THE RISK

Low Risk

Why gateway_list needs a policy

The naming convention suggests this tool retrieves or enumerates gateway resources from EKS without side effects. Although the description is empty, the verb 'list' in the name strongly indicates a Read operation. Confidence is moderate rather than high due to the lack of descriptive text, but the naming pattern aligns clearly with non-destructive data retrieval operations.

From the tool's definition Tool name 'gateway_list' indicates a listing/querying operation typical of Read category tools (list, get, fetch). The 'list' verb specifically suggests retrieval without modification.

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

POLICY

How to control gateway_list

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_list:

policy.json

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

gateway_list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
