## Description

Handling Brazilian payroll isn't a simple math problem; it's a minefield of specific laws. This MCP gives your AI agent the specialized engine needed to calculate every essential component of CLT-governed paychecks. Instead of manually cross-referencing progressive deduction tables for INSS and applying complex tax brackets for IRRF, you simply ask your agent what the numbers should be. It calculates the precise deductions, determines the employee's net take-home salary, and, critically, figures out the total economic impact on the company. You get clear answers regarding statutory charges like FGTS or other employer burdens. Connect this MCP through Vinkius to give any compatible client—like Cursor or Claude—the ability to perform these detailed financial checks instantly, freeing up your team from compliance guesswork.

## Capabilities

### Estimate Total Employer Cost
Calculates the company's total expenditure for an employee, including all statutory charges and burdens.

### Determine Income Tax Deductions (IRRF)
Applies Brazilian federal tax rules to calculate the specific amount of income tax withheld from a paycheck.

### Calculate Progressive INSS Deduction
Determines the required Social Security deduction, applying progressive rate changes based on salary tiers.

### Compute Employee Net Pay

## Use Cases

### Determining the True Cost of Hiring
A finance manager needs to know if they can afford to hire someone. Instead of just looking at the base salary, they use the calculate_employer_total_cost tool via their agent. The result gives them the full picture—the true cost burden on the company.

### Running a Mid-Year Payroll Audit
The HR team needs to verify if previous paychecks correctly applied progressive INSS deductions for a group of employees. They use get_social_security_deduction repeatedly, quickly cross-checking compliance across dozens of records.

### Responding to Complex Pay Questions
An employee asks why their paycheck is lower than expected due to tax changes. The agent runs the necessary deductions using get_income_tax_deduction and calculate_employee_net_pay, providing a precise, immediate answer.

### Simulating Salary Adjustments
A manager needs to see how a raise impacts total payroll. They feed the new salary into all four tools—from get_social_security_deduction up through calculate_employer_total_cost—to present the full financial picture.
