WHAT IT DOES

What get_graph_status does on Amazon Bedrock Knowledge Base Retrieval MCP Server

AI agents call get_graph_status 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_graph_status needs a policy

This tool retrieves status information about an existing Neptune graph. It performs a query-only operation with no ability to modify, delete, or execute operations. The status query has minimal blast radius even if called arbitrarily by an AI agent.

From the tool's definition Tool name is 'get_graph_status' and description states 'Get the status of the currently configured Amazon Neptune graph' — uses the verb 'Get' which indicates a retrieval operation with no side effects.

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

POLICY

How to control get_graph_status

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_graph_status:

policy.json

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

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