WHAT IT DOES

What get_eks_vpc_config does on Amazon Bedrock Knowledge Base Retrieval MCP Server

AI agents call get_eks_vpc_config to retrieve information from Amazon Bedrock Knowledge Base Retrieval 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_eks_vpc_config needs a policy

The 'get_' prefix is a strong indicator of a retrieval operation. Reading EKS VPC configuration is a non-destructive query that would retrieve existing infrastructure metadata. Given the empty description, confidence is moderately reduced, but the tool name alone provides sufficient signal for a Read classification with low severity.

From the tool's definition Tool name 'get_eks_vpc_config' contains 'get', which is a canonical Read operation that retrieves configuration data.

POLICY

How to control get_eks_vpc_config

PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon Bedrock Knowledge Base Retrieval MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_eks_vpc_config:

policy.json

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

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