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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "get_vol_regime",
    "arguments": {
      "coin": "<coin>"
    }
  }
}
```

## Why get_vol_regime is rated Low

This is a data retrieval tool that calculates and returns volatility regime classification based on historical price data. It has no side effects, does not execute code or commands, does not modify or delete data, and does not move funds. The $0.12 cost is a query fee, not a financial transaction. It falls squarely into the Read category.

From the tool's own definition: "Tool name 'get_vol_regime' and description indicate retrieval of volatility classification metrics ('compressed/normal/expanded/extreme' based on rolling volatility percentile)."

## Use case

AI agents call get_vol_regime to retrieve information from Crypto Intelligence 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 Crypto Intelligence:

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