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

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

## Why BinanceSubAccountAssets is rated Low

This tool only queries and retrieves financial account data (asset balances) without creating, modifying, or moving funds. It falls clearly into the Read category. However, severity is high because unauthorized access to detailed account balances of a sub-account could enable financial reconnaissance, phishing, or social engineering attacks, and is sensitive financial information.

From the tool's own definition: "Tool retrieves 'detailed asset balances' and 'shows all tokens and their free/locked amounts' with no modification, deletion, or execution capability described."

## Use case

AI agents call BinanceSubAccountAssets to retrieve information from Binance MCP 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 Binance MCP Server:

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