MCP tools — 10 exposed · ~1,935 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.

Tool Tokens
affordability_estimate ~226

Compute front-end (housing) and back-end (total debt) DTI budgets from income and debts, and the home price implied by the binding limit. Reports the standard 28/36 thresholds without ever telling the user what they "can afford". Dollar inputs are US dollars; money in the response is integer cents.

NameTypeReqDescription
backEndLimitPctnumberTotal DTI ceiling percent (default 36)
downPaymentnumberDown payment available, US dollars
frontEndLimitPctnumberHousing DTI ceiling percent (default 28)
grossMonthlyIncomenumberyesGross monthly income, US dollars
insuranceAnnualnumberAnnual homeowners insurance premium, US dollars
monthlyDebtsnumberRecurring monthly debt payments (cards, autos, student loans), US dollars
propertyTaxRatePctnumberAnnual property tax rate, % of value
rateAnnualPctnumberAnnual interest rate percent
termYearsintegerLoan term in years (default 30)

No output schema declared.

No examples provided.

benchmark_rates ~52

Return the latest benchmark mortgage rates (e.g. 30-year and 15-year fixed) from the Federal Reserve (FRED), each with its observation date and ledger receipt. Rates are fixed-precision percent strings.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

decode_loan_estimate_fee ~88

Classify a mortgage Loan Estimate fee by CFPB section and control class (set by lender, shoppable, third-party, government, or prepaid), with a plain-language explanation and an educational question a buyer could ask. Omit "fee" to list the full catalog.

NameTypeReqDescription
feestringFee name or keyword, e.g. "origination", "title"

No output schema declared.

No examples provided.

fee_benchmarks ~150

Return closing-cost and rate-spread percentile distributions (p25/p50/p75 + mean) for a US state, computed from the row-level CFPB HMDA LAR for originated, first-lien, home-purchase loans. Cells with fewer than 25 records are suppressed. Dollar metrics are integer cents (…Cents); percent metrics are fixed-precision strings (…Pct). Each distribution carries a ledger receipt hash for verification.

NameTypeReqDescription
metricstringOne of: total_loan_costs, origination_charges, rate_spread, interest_rate. Omit to return all metrics.
statestringyesTwo-letter US state code, e.g. "MA"

No output schema declared.

No examples provided.

payment_shock_estimate ~250

Estimate why a mortgage payment often jumps in year two: escrow at closing is sized from the seller's current tax bill, but the county reassesses at your purchase price, and RESPA spreads the resulting escrow shortage over 12 months. Given the purchase price, the seller's current annual tax (from the listing), a state (or county FIPS) for the reassessment rate, and insurance, returns the year-1 escrow, the year-2 ongoing escrow, the temporary catch-up peak, and the jump. Money is integer cents. This decomposes the mechanics; it is not a prediction of your specific bill.

NameTypeReqDescription
countystring5-digit county FIPS; its Census effective rate takes priority over the state rate
insuranceAnnualnumberAnnual homeowners insurance, US dollars
purchasePricenumberyesPurchase price in US dollars
reassessRatePctnumberEffective annual property-tax rate at reassessment, %. Overrides county/state.
sellersCurrentAnnualTaxnumberyesSeller's current annual property tax in US dollars (from the listing)
statestringTwo-letter US state code for the reassessment rate

No output schema declared.

No examples provided.

pressure_check ~249

Decompose the tradeoff a rushed buyer faces: the earnest money at risk by walking away versus what overpaying to "win" costs over the life of the loan. Given the earnest money at risk, the overpay amount over your walk-away price, down-payment percent, rate, and term, returns the cash and financed shares of the overpay, the extra monthly P&I, the lifetime cost of overpaying, and its ratio to the earnest money. Money is integer cents. Educational decomposition — it names the two numbers so they can be compared; it never tells the user to walk or stay.

NameTypeReqDescription
downPaymentPctnumberDown payment as a percent of price (0–100); splits the overpay into cash-at-close vs. financed
earnestMoneynumberyesEarnest money at risk if you walk away after removing contingencies, US dollars
overpaynumberyesHow much over your walk-away price the pressure would push you to pay, US dollars
rateAnnualPctnumberAnnual interest rate percent, e.g. 6.5
termYearsintegerLoan term in years (default 30)

No output schema declared.

No examples provided.

rent_vs_buy_estimate ~368

Compare the net cost of owning against renting over a holding period and find the break-even year. Owning nets upfront cash and recurring carrying costs against sale proceeds (appreciated value − selling costs − remaining loan); renting nets rent paid against the investment gain on the cash a buyer would tie up. Dollar inputs are US dollars; money in the response is integer cents. Appreciation, rent growth, and investment return are user-set assumptions. Tax deductions are excluded (documented simplification). Educational decomposition — it reports both net costs and the break-even year; it never says rent or buy.

NameTypeReqDescription
annualAppreciationPctnumberAssumed annual home-price appreciation percent
annualRentIncreasePctnumberAssumed annual rent increase percent
closingCostPctnumberUpfront buy-side closing costs, % of price
downPaymentPctnumberDown payment as a percent of price
hoaMonthlynumberMonthly HOA dues, US dollars

homePricenumberyesHome price in US dollars
insuranceAnnualnumberAnnual homeowners insurance, US dollars
investmentReturnPctnumberAssumed annual return a renter earns on invested cash percent
maintenanceRatePctnumberAnnual maintenance reserve, % of home value
monthlyRentnumberyesComparable monthly rent in US dollars
propertyTaxRatePctnumberAnnual property tax rate, % of value

termYearsintegerLoan term in years

search_dpa_programs ~95

Find down payment assistance (DPA) programs by US state and/or buyer type. Includes national programs. Each result links to its official government source and carries a ledger receipt and last-verified date.

NameTypeReqDescription
buyerstringBuyer type filter, e.g. "first-time", "veteran", "rural", "teacher"
statestringTwo-letter US state code to filter by

true_cost_estimate ~384

Estimate the full monthly cost of owning a home — principal & interest, property tax, insurance, PMI, HOA, and maintenance — and contrast it with the lender "approval" payment (PITI+PMI) to reveal the hidden monthly gap. Dollar inputs are US dollars; all money in the response is integer cents; rates are fixed-precision percent strings.

NameTypeReqDescription
countystring5-digit county FIPS code. When provided and its Census county rate is available, it takes priority over the state rate (more accurate).
downPaymentPctnumberDown payment as a percent of price (0–100)
hoaMonthlynumberMonthly HOA dues, US dollars
homePricenumberyesHome price in US dollars
homeYearBuiltintegerYear the home was built. Scales the maintenance reserve by age band: ×1.5 pre-1980, ×1.2 1980–2005, ×1.0 2006+.
insuranceAnnualnumberAnnual homeowners insurance premium, US dollars
maintenanceRatePctnumberAnnual maintenance reserve, % of home value (baseline before age adjustment)
pmiAnnualRatePctnumberAnnual PMI rate, % of loan, applied while LTV > 80%
propertyTaxRatePctnumberAnnual property tax rate, % of value. Overrides county/state-derived rates when supplied.
rateAnnualPctnumberAnnual interest rate percent, e.g. 6.5
statestringTwo-letter US state code (e.g. "NJ"). When provided and propertyTaxRatePct is omitted, the Census ACS effective property-tax rate for that state is used.

verify_receipt ~73

Verify a CandidCost ledger receipt hash (full sha256 or short "3f9a…c21e" form). Confirms the receipt exists and that its dataset hash chain is intact, proving the underlying data has not been altered since ingestion.

NameTypeReqDescription
