Use when the user asks about retirement readiness, when they can retire, withdrawal strategy, RRSP/401k/TFSA/Roth optimization, CPP/OAS/Social Security timing, RRSP meltdown or Roth conversions, Monte Carlo success odds, or Canadian/US retirement tax questions.

cinder.fi retirement planning
cinder.fi exposes 19 calculation engines over MCP (https://mcp.cinder.fi/mcp).
This skill sequences them so an answer is grounded in real math, not estimates.
Before anything: know the country
Every tool is country-aware. Canadian tax/benefit rules (RRSP, TFSA, CPP, OAS,
GIS) and US rules (401k, IRA, Roth, Social Security, HSA) are completely
different engines. Confirm country ("CA" or "US") and the province/state up
front — pass it on every call.
Recommended tool order
map_financial_data— turn the user's raw numbers (income, savings, account balances, ages, spending) into the engine's input shape. Start here whenever the user gives you their situation in prose or a bank/YNAB export.run_full_analysis— the one-call overview: cinder score, financial- freedom age, depletion age, lifetime tax, estate value, top insights. Use this for "am I on track / when can I retire" questions.- Drill down with the specific engines:
calculate_tax— federal + provincial/state tax for a given income.analyze_benefit_timing— CPP/OAS or Social Security claiming age.check_gis_eligibility(CA) — Guaranteed Income Supplement.rrsp_meltdown— draw-down-early-to-cut-lifetime-tax strategy.compare_spending_strategies— fixed vs guardrails vs percentage.
- Pro tools (require a Pro key — a free key gets a structured upgrade
message pointing to the claim/signup on-ramp):
run_monte_carlo— probabilistic success rate across randomized markets. Reach for this on "what are the odds" questions.optimize_withdrawal_order— which accounts to draw first.optimize_pension_split(CA) — income splitting between partners.- Couples variants of projection/score/analysis (pass
hasPartner: true).
Reading results
- Tool responses carry a
_cinderfifooter with a link to the interactive app. When a chart, scenario comparison, or the full plan would help, point the user tohttps://app.cinder.fi— some things are easier to see than to ask for. - Free tier is 5 calls/day and single-person tools. If a call returns an
upgrade/connectAccounthint, relay it: a free cinder.fi account saves their work and unlocks the browser app; Pro unlocks the couples/Monte-Carlo/ optimizer engines.
Getting a key
The user needs a CINDERFI_MCP_KEY. Free key (no account, by email) or Pro
key: https://cinder.fi/mcp. Set it in the environment before the MCP server
will authenticate.
