Instead of calculating every person individually in Excel, they use `compare_salary_scenarios` with the old and new gross pay rates. The agent instantly reports the total net pay increase across all employees, making budget approval fast. ### Onboarding New Hires An HR coordinator is talking to a potential employee who asks what their actual take-home salary will be. They run `calculate_net_payroll` with the offer amount and get the exact net pay, including all deductions, giving the candidate immediate confidence. ### Auditing Payroll Records A bookkeeper suspects a previous payroll cycle might have used outdated tax rates. They first run `get_tax_configuration` to verify the active ruleset, then use that output to validate all historical records. ### Budgeting for Q3 Compensation A finance director needs to see how much net pay their department will receive if they budget for two potential bonus levels (low and high). They feed both scenarios into the comparison function, giving a clear financial range. ## Benefits - Stop guessing deductions.

First, check the current tax rules using the configuration tool. This sets your baseline for compliance. 2.

Finally, if you're comparing options, use the scenario comparison tool to see the net pay difference between two different starting salaries. ## Frequently Asked Questions **How do I use the `calculate_net_payroll` tool?** You provide the MCP with a single gross salary amount. The tool then returns your precise net pay, automatically subtracting INSS and IRRF based on current tax law. **I need to know the latest deduction rates; how do I use `get_tax_configuration`?** Simply prompt the MCP with 'show tax configuration.' This tool pulls the live, necessary rates for INSS, IRRF, and FGTS directly from the system's current database. **How does `compare_salary_scenarios` work?** This tool takes two separate gross salary figures. It runs both through the full deduction process and shows you a clear report of the net pay difference between them. **`calculate_net_payroll` handles all tax deductions, right?** Yes. The main calculation tool applies progressive brackets for INSS and IRRF while also accounting for FGTS, giving you a complete picture of your take-home pay. **What should I do if I get an error running `calculate_net_payroll`?** The system sends a detailed error code and message. This usually means the input data is missing or formatted incorrectly, so you just need to check your required fields. **Can `calculate_net_payroll` process deductions beyond INSS, IRRF, and FGTS?** No. This MCP focuses narrowly on calculating net salary based on the standard progressive brackets for INSS and IRRF, plus the fixed rate for FGTS. It won't account for other voluntary dues. **Before I use `compare_salary_scenarios`, how do I confirm the latest tax rules are active?** First, call `get_tax_configuration`. This tool pulls the current official brackets for INSS and IRRF. You'll want to check this before comparing salaries to ensure accuracy. **Are there limitations on how frequently I can use `calculate_net_payroll`?** No explicit rate limits restrict standard usage through Vinkius.
