Get estimated delivery dates and transit times between two locations. Returns the expected delivery date and time for each available UPS service.
AI agents call get_time_in_transit to retrieve information from UPS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries UPS transit time estimates between locations, a pure information retrieval operation with no side effects, data modification, or irreversible actions. Low severity because misuse poses minimal risk—an agent could only retrieve delivery estimates, not create shipments, cancel operations, or affect financial transactions.
From the tool's definition Tool name 'get_time_in_transit' and description 'Get estimated delivery dates and transit times' indicate a query operation that retrieves information without modifying, deleting, or executing external actions.
