## Tools
- calculate_fire_target - Estimate the savings target needed for Financial Independence / Early Retirement. Runs Monte Carlo simulation and returns the probability the portfolio survives the planning horizon. Endpoint: https://mcp.retirecrunch.com/mcp
- calculate_coast_fire - Compute the Coast FIRE milestone — the capital required today such that, with no further contributions, a portfolio compounds to the user's retirement target by their target age. Endpoint: https://mcp.retirecrunch.com/mcp
- compute_swiss_property_tax - Estimate the Swiss cantonal real-estate capital gains tax (Grundstückgewinnsteuer) for a property sale. Covers all 26 cantons with holding-period adjustments and Ersatzbeschaffung (replacement-residence) deferral. Educational estimate; commune surcharges and value-enhancing-improvement deductions are not modeled. Endpoint: https://mcp.retirecrunch.com/mcp
- project_wealth_plan - Run RetireCrunch's full year-by-year Wealth Plan projection for a household. Models earned income, pensions, expenses, portfolio growth, optional growth→income phase switch, mortgage amortization, optional property sale, and region-aware tax (US uses 2026 federal+state brackets; other regions use a flat rate). Returns a compact summary with 5-year milestones by default, or the full annual array when yearly_detail=true. Endpoint: https://mcp.retirecrunch.com/mcp
- get_portfolio_returns - Return RetireCrunch's historical portfolio return profiles for a currency. Each profile is a (return %, volatility %) pair derived from real index data — useful for grounding the assumptions in calculate_fire_target / project_wealth_plan in something defensible rather than guessing.
