## Why crypto_dex is rated Low

This tool only queries and displays market information from DexScreener. It does not execute trades, move funds, create orders, or modify blockchain state. The financial context (crypto/DEX) is present in the data *domain*, but the tool itself performs read-only operations. The cost is a standard API fee, not a financial transaction.

From the tool's own definition: "Tool retrieves 'Live DEX market data (price, liquidity, 24h volume, FDV, market cap, chain)' — purely data retrieval with no mutations, no fund transfers, and no execution of trades."

## Use case

AI agents call crypto_dex to retrieve information from Omnicall — Agent Tools Gateway 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 Omnicall — Agent Tools Gateway:

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