## Why get_ticker is rated Low

This tool queries market information (ticker data) without creating orders, executing trades, or modifying any state. It is a pure read operation similar to get_orderbook, get_market, and get_candles on the same server. The blast radius of misuse is minimal—an agent could only retrieve stale or misleading pricing data, not commit financial harm directly.

From the tool's own definition: "Tool name 'get_ticker' and description 'Current best bid / best ask / last price for a market' indicate retrieval of real-time market data with no modification or execution of trades."

## Use case

AI agents call get_ticker to retrieve information from Lighter MCP 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 Lighter MCP:

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