## Why get_overview_fees is rated Low

This tool fetches and aggregates historical fee and revenue data from DefiLlama's API. The verb 'List' and the nature of returning summaries and historical data confirm this is a read-only operation with no side effects. There is no capability to modify data, execute code, delete information, or perform financial transactions.

From the tool's own definition: "Tool name 'get_overview_fees' and description 'List all protocols along with summaries of their fees and revenue and dataType history data' indicate a retrieval/query operation with no modification or execution of code."

## Use case

AI agents call get_overview_fees to retrieve information from Defillama 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 Defillama:

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