## Why get_dex_summary is rated Low

This tool appears to query and return DEX summary data without modifying state, matching the Read category. The empty description lowers confidence slightly, but the naming convention and server context strongly suggest a data retrieval function.

From the tool's own definition: "Tool name 'get_dex_summary' indicates data retrieval of DEX (decentralized exchange) summary information. The description is empty, but the context shows this server provides 'crypto data retrieval' and sibling tools (get_active_users, get_balances_address,…"

## Use case

AI agents call get_dex_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)
