WHAT IT DOES

What get_children does on Enhanced Knowledge Graph Memory Server

AI agents call get_children to retrieve information from Enhanced Knowledge Graph Memory Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why get_children is rated Low

This tool retrieves hierarchical relationship data from the knowledge graph. It has no side effects, does not modify state, and poses minimal risk if invoked by an AI agent. The worst-case misuse would be exposing the structure of stored entities, which is a read-only information disclosure risk at most.

From the tool's definition Tool name 'get_children' and description 'Get all child entities of an entity' indicate a retrieval operation that queries the knowledge graph structure without modifying, deleting, or executing external operations.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs get_children safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Enhanced Knowledge Graph Memory Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_children, this is the rule to start with:

get_children Allowed

get_children is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Enhanced Knowledge Graph Memory Server, apply this rule, and every get_children call is checked against it from then on.
