## Why get_ticker is rated Low

This tool queries and retrieves current ticker information (price, volume, bid/ask spreads) from a public financial data API. It has no side effects, does not modify data, execute commands, delete information, or move funds. The severity is low because misuse would only expose publicly available market data that the user could access directly through the Derive API.

From the tool's own definition: "Tool description states 'Get current price, volume, bid/ask for an instrument' - retrieves read-only market data with no modification or side effects."

## Use case

AI agents call get_ticker to retrieve information from Derive 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 Derive MCP Server:

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