AI agents call get_lead to retrieve information from Mycase without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves a single lead record by its identifier. Retrieval operations that query data without side effects are classified as Read. The low severity reflects that accessing lead information in a law firm CRM poses minimal risk—it does not modify data, execute external operations, delete records, or move funds. The confidence is high because the intent is unambiguous.
From the tool's definition Tool name 'get_lead' and description 'Get a lead by ID' indicate a retrieval operation with no modification or destructive capability.
