## Why get_market_volatility is rated Low

This tool only queries and retrieves market data (volatility metrics). It has no side effects—it does not execute trades, transfer funds, modify balances, or delete data. While the server context involves cryptocurrency operations, this specific tool is purely Read-category: it gathers information to inform decisions but does not execute those decisions.

From the tool's own definition: "Tool name 'get_market_volatility' and description state it retrieves 'current and historical volatility metrics' with no mention of modification, deletion, or financial transactions."

## Use case

AI agents call get_market_volatility to retrieve information from Agenti 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 Agenti:

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