AI agents call list_balances_leases to retrieve information from Wpm Mcp Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a straightforward data retrieval operation by filtering and returning lease records based on balance criteria. It does not create, modify, delete, or execute any operations—it only reads and returns existing data. The low severity reflects that unauthorized access would be informational rather than actionable damage.
From the tool's definition Tool name contains 'list' and description states 'Retrieves a list of leases that have outstanding balances.' This is a query operation that retrieves data with no side effects.
