## Why ccxt_fetch_ticker is rated Low

This is a read-only operation that retrieves current market ticker data (price, volume, etc.) for a given symbol. It has no side effects, does not execute trades, does not modify account data, and does not delete or create records. The 'fetch' operation pattern is characteristic of Read category tools. Despite being on a trading-focused server, this specific tool only queries market data.

From the tool's own definition: "Tool name 'fetch_ticker' and description 'Call exchange.fetchTicker(symbol, params)' indicate a data retrieval operation that queries market ticker information from an exchange without modifying state."

## Use case

AI agents call ccxt_fetch_ticker to retrieve information from Codex CCXT 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 Codex CCXT MCP:

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