## Why get_order_book is rated Low

This tool only fetches read-only market data (order book depth) from Bybit's API. It performs no writes, executions, or financial transactions. Misuse potential is minimal as it only returns publicly available market information.

From the tool's own definition: "'Get order book depth for a trading symbol' — retrieves market data with no side effects"

## Use case

AI agents call get_order_book to retrieve information from Bybit 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 Bybit MCP Server:

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