Volatility Analysis in Claude Desktop

The `evaluate_portfolio_risk_profile` tool breaks down the actual volatility of your asset mix using this MCP. Your agent runs these numbers directly in your Claude Desktop chat window to show you how a bad market year eats your principal. This allows you to adjust your equity and bond ratios on the fly in Claude Desktop. You see the hard numbers behind different allocation strategies without exporting data to external financial software.

Run Survival Probability Math

You run the core math of your plan using `simulate_withdrawal_probabilities` to test survival rates at 0%, 3.5%, 4.0%, and 4.5% withdrawal marks. The math is stubborn, and this is where people trip up, because looking at raw survival rates prevents you from relying on blind optimism. Claude Desktop displays these probabilities instantly. You immediately know if your plan survives a historical sequence of bad market years or if you need to adjust your living expenses.

Stress-Test Worst-Case Scenarios

The `get_scenario_extremes` tool identifies the absolute limit of what your portfolio successfully endured in historical market simulations. This shows you the highest cumulative amount of cash withdrawn in a single run before failure. Knowing the worst-case boundary helps you build a cash buffer. Your agent helps you plan for the absolute bottom of the market in Claude Desktop, because hope is not a strategy.
