## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "get_parent",
    "arguments": {}
  }
}
```

## Why get_parent is rated Low

This tool retrieves hierarchical relationship information from a knowledge graph storage system. It performs a data query to identify a parent entity reference, which is a read-only operation with no side effects, data modification, or external state changes. The low severity reflects minimal blast radius if misused—an agent could only retrieve information about relationships that already exist in the graph.

From the tool's own definition: "Tool name 'get_parent' and description 'Get the parent entity of an entity' indicate a retrieval operation that queries relationship metadata without modification."

## Use case

AI agents call get_parent 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.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Enhanced Knowledge Graph Memory Server:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_parent": {}
  }
}
```
