Is it safe to expose my company's payrolls to the AI?

Yes. This connector runs entirely on your local machine or trusted enclave natively. No employee data, payload information or generated queries are routed to our servers—your API interactions occur directly from your environment straight to SmartHR's endpoints.

Can the agent calculate average payroll over time automatically?

Absolutely. Just prompt your agent: 'List all payrolls from Q2, and display the average distribution'. The agent will call the `list_payrolls` endpoint, retrieve the raw figures, do the mathematical operation independently in context, and present you a very clear table or markdown summary.

How do I look up which internal department an employee works for?

You don't need to specify the exact tool. You can simply ask: 'What department is crew member [Name] in?'. Your AI will automatically use the `list_crews` tool and cross reference the results with `list_departments` to formulate a correct response.
