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

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

## Why get_heapsnapshot_edges is rated Low

This tool queries and retrieves memory snapshot data for analysis purposes. It reads existing heap snapshot information and returns references without creating, modifying, deleting, or executing code. The operation is read-only and non-destructive, making it a Read category tool with low severity since heap analysis cannot directly harm system state or external data.

From the tool's own definition: "Tool description states it 'Loads a memory heapsnapshot and returns outgoing edges' — a retrieval operation with no modification or deletion. The verb 'returns' indicates data querying only."

## Use case

AI agents call get_heapsnapshot_edges to retrieve information from Chrome Devtools 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 Chrome Devtools:

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