This MCP server provides a specialized calculation engine for determining personal income tax liabilities in France. It implements the complex 'quotient familial' system, which adjusts taxable income based on the number of dependents (children) in a household. By using tools like calculate_tax_burden, users can determine their total tax liability, including social contributions (CSG/CRDS), and see their resulting net income. The server also includes compute_fiscal_parts to calculate household parts and assess_marginal_pressure to analyze the difference between average and marginal tax rates. It is an essential tool for financial planning and understanding the impact of family changes on French taxation.

How much tax will I pay if my gross taxable income is 50,000 EUR and I have 2 children?

With a gross income of 50,000 EUR and 2 children, your total tax liability is approximately 4,875.00 EUR, which includes both income tax and social contributions (CSG/CRDS). Your estimated net income would be 45,125.00 EUR.

Calculate the number of fiscal parts for a household with 3 children.

A household with 3 children is entitled to 2.5 fiscal parts (1 base + 0.5 for the first child + 0.5 for the second child + 0.5 for the third child).

What is my tax pressure if I earn 100,000 EUR with no children?

With an income of 100,000 EUR and no children, your average tax rate is approximately 20.45%, while your marginal tax rate is 41%. This results in a significant gap between the two rates.

The system divides your taxable income by a number of 'fiscal parts' determined by your household size and children. This reduces the amount of income subject to higher tax brackets.

Accessibility Prover MCP

Accessibility Prover is a pre-build validation system that forces WCAG 2.2 AA compliance before code is written. It audits semantic HTML, keyboard navigation, contrast ratios (4.5:1 minimum), screen reader compatibility, and motion safety across 5 structured Decision Pivots. Unlike runtime scanners, it catches div soup, missing focus traps, and inaccessible animations during the design phase — before they reach production and before they violate the European Accessibility Act (EAA 2025).
