## Why ccxt_fetch_leverage_tiers is rated Low

This tool retrieves leverage tier data for specified symbols from a cryptocurrency exchange. It is a read-only query operation that has no side effects on account state, positions, or balances. The blast radius of misuse is minimal—an attacker could only gain visibility into leverage tier structures, which is informational metadata already publicly available or accessible through standard exchange APIs.

From the tool's own definition: "Tool name 'ccxt_fetch_leverage_tiers' and description 'Call exchange.fetchLeverageTiers(symbols, params)' indicate a fetch/query operation that retrieves leverage tier information from an exchange."

## Use case
