Check if a specific lead is in the working leads list.
AI agents call checkWorkingLead to retrieve information from Lofty 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 simple lookup/query to determine membership in a list. It retrieves data without creating, modifying, deleting, or executing any operations. The blast radius is minimal as misuse would only expose query results about lead assignments, not enable destructive or financial actions.
From the tool's definition Tool name is 'checkWorkingLead' and description states it 'Check[s] if a specific lead is in the working leads list' — a query operation that retrieves status information with no modifications or side effects.
