SUBSCRIBER PERK
Connect the grounded calculators to your own AI.
The same source-verified 2026 calculators the Roth Accelerator AI uses are available as an MCP server. Add it to your own Claude or ChatGPT and your assistant can run the widow's-penalty, RMD, inherited-IRA, and break-even math from the book's verified figures — instead of guessing.
MCP server URL
https://chigfkvoilnttscdypgu.supabase.co/functions/v1/mcp-toolsWhat it exposes
federal_tax— 2026 federal tax on ordinary income.widow_penalty— The single-filer year after.rmd_escalator— RMDs from 73 through your 90s.inherited_ira— 10-year drawdown tax bill for heirs.roth_crossover— When the conversion breaks even.bracket_headroom— Room left inside your current bracket.
Each returns a 2026 figure with its arithmetic; it refuses anything it can't ground.
