## Why compareYieldTool is rated Low

This is a read-only analysis tool that queries yield data to help inform investment decisions. It gathers information across DeFi protocols but does not execute trades, transfer assets, or trigger any irreversible actions. While it exists in a financial context (cryptocurrency yield), the tool itself performs no financial transactions or commitments.

From the tool's own definition: "The tool 'compares yield opportunities for specific assets across different protocols' — it retrieves and analyzes yield data across protocols without modifying state, executing transactions, or moving funds."

## Use case

AI agents call compareYieldTool to retrieve information from Agentek Eth 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 Agentek Eth:

```json

  }
