## Why binance_us_cust_supported_assets is rated Low

This tool queries and returns static configuration data about which assets are eligible for custodial operations. It performs no financial transactions, creates no orders, modifies no account state, and executes no transfers. Despite being on a financial exchange server and requiring API credentials, the tool itself is a read-only lookup of asset eligibility lists.

From the tool's own definition: "Tool description states it 'Get[s] list of assets' and 'Response includes' asset information. Verbs are purely informational: 'transferEligible', 'settlementEligible' are status fields, not actions that modify or transfer funds."
