## Why get_supported_dexes is rated Low

This tool queries metadata about supported DEXes and their slugs to inform other operations. It has no side effects, executes no transactions, modifies no data, and moves no funds. It is purely informational retrieval, placing it in the Read category with low severity.

From the tool's own definition: "Tool description states it 'Returns the AMMs / DEX sources' — a read-only operation that retrieves and lists supported DEX information with no modifications or side effects."

## Use case

AI agents call get_supported_dexes to retrieve information from Swapwizard 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)

```json
{
  "version": "1",
