AI agents call calculate_working_days to retrieve information from Mcp Europe Business without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool performs a read-only calculation over date ranges and holiday calendars. It returns computed information (working day count) without creating, modifying, deleting, or executing any external operations. The severity is low because misuse poses minimal risk: worst case would be incorrect business calculations rather than data loss, financial impact, or system compromise.
From the tool's definition Tool description states it 'Counts the number of working days between two dates' and 'Returns { start_date, end_date, working_days: number }'.
