## Why get_fees_summary is rated Low

This tool retrieves fee summary data for a specified crypto protocol. It performs a query operation without side effects, reversible modifications, or destructive actions. The blast radius of misuse is minimal—an agent could only retrieve publicly available fee statistics, not alter data or execute external operations. Classified as Read with low severity.

From the tool's own definition: "Tool name 'get_fees_summary' and endpoint 'GET /api/summary/fees/{protocol}' clearly indicate data retrieval only. The HTTP GET method and lack of any mutation keywords (create, update, delete, post) confirm read-only operation."

## Use case

AI agents call get_fees_summary to retrieve information from REI Crypto MCP Server 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 REI Crypto MCP Server:

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