Connects to Singapore mortgage market data and regulatory rules. Helps compare bank packages, calculate monthly payments and total interest, check affordability under TDSR/MSR limits, estimate stamp duty, and model purchase timelines for HDB and private properties.

Example request: "Show me the best mortgage packages for a 500,000 SGD HDB purchase and calculate my monthly payment."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Cashew MCP to help me. It is a free service with an MCP server at https://www.cashew.sg/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Tools:
- recommend_packages: Rank Singapore mortgage packages for a borrower. Returns `recommended` (up to 3 picks, each with a package id and `reasoning`; ranked by the LLM when `userContext` is given, otherwise the cheapest package of each rate structure), `lowestRateIds` (up to 3 package ids, cheapest eli
- compare_packages: Compare 2–3 SPECIFIC mortgage packages side by side: average rate over the lock-in, benchmark index, effective rate and monthly instalment per year, interest paid per year, and flexibility terms (prepayment, free conversion, sale waiver, penalties, minimum loan). Pass `packageIds
- list_banks: List active banks (id + name), sorted by name. Use this to map a borrower's current lender name to the `currentBankId` UUID required by `recommend_packages` for refinance deals.
- get_property_valuation: Indicative SPML valuation for a Singapore unit. Requires postal code and unit number in FF-SS format (e.g. "04-02"). propertyType ("Condo" or "HDB") and areaSqft are optional — when propertyType is omitted, both types are probed and the one that values the unit is used (`property
- calculate_package_schedule: Compute the amortisation schedule for a SPECIFIC mortgage package using that package's real effective rates. Use this once the borrower has picked a package from `recommend_packages`; for a hypothetical "what-if" rate the borrower does not yet hold a package for, use `calculate_m
- list_market_indices: List market benchmark indices (id, slug, name, currency), sorted by slug. Use this to resolve a benchmark name like 'SORA' into the `marketIndexId` required by `get_index_quotes`.
- get_index_quotes: Return historical quotes (rate by date) for a market benchmark index such as SORA. Requires `marketIndexId` — use `list_market_indices` to resolve a benchmark name/slug into its UUID. Optional `startDate`/`endDate` narrow the range; results are paginated, newest first. Quote `rat
- calculate_affordability: Estimate the maximum loan and property price a borrower can afford from income, existing debt commitments and tenure, applying Singapore TDSR/MSR limits. Use this when you know the income and want the budget; to go the other way (a target price → the income needed), use `calculat
- calculate_required_income: Reverse affordability: work out the gross monthly income needed to support a target property price under Singapore TDSR/MSR limits. Use this when you know the target property price; to go the other way (income → maximum budget), use `calculate_affordability`.
- calculate_mortgage_repayment: Compute the monthly repayment, total interest and total cost for a hypothetical loan from an interest rate you supply (standard amortisation). Use this for "what-if" rates; for the real rates of a specific package the borrower has chosen, use `calculate_package_schedule` instead.
- calculate_refinance_savings: Compare a borrower's existing mortgage against a new rate and report monthly savings, total savings and break-even months. Set `mode` to 'original' (supply the original loan amount, tenure and start date) or 'remaining' (supply the current outstanding balance and remaining tenure
- calculate_residential_stamp_duty: Compute Buyer's Stamp Duty (BSD) and Additional Buyer's Stamp Duty (ABSD) for a Singapore residential purchase, given price/value, buyer type (singaporean | pr | foreigner | entity | trust) and the number of residential properties already owned.
- calculate_rental_stamp_duty: Compute the stamp duty payable on a property lease from the rent and lease term.
- calculate_mortgage_stamp_duty: Compute the stamp duty payable on a mortgage/loan facility.
- calculate_seller_stamp_duty: Compute Seller's Stamp Duty (SSD) from the sale price/value and how long the property has been held.
- analyze_sell_one_buy_two: Analyse a 'sell one, buy two' plan where two co-owners sell their joint home. Returns the sale proceeds (cash after loan, CPF refunds, SSD and legal fees) and each buyer's resulting cash and CPF. With `buy1`, it compares buying one replacement jointly or under either buyer alone;
- check_eligibility: Run the regulatory affordability gate for one main borrower and up to three joint borrowers. Given each borrower's income, rental, pledged/unpledged assets and liabilities plus a proposed loan, returns the qualifying income (after MAS haircuts), the TDSR and MSR for the proposed 
- analyze_decoupling: Analyse decoupling: the cost versus benefit of transferring one co-owner's share so a borrower is freed up for another purchase (including stamp duty).
- calculate_sales_proceeds: Work out what a seller walks away with when selling a property: cash proceeds after redeeming the outstanding loan, refunding each owner’s CPF (principal plus accrued interest, 1 to 4 owners), and paying agent commission (with 9% GST), legal and miscellaneous fees. Flags a negati
- calculate_purchase_cost: Calculate the full upfront cost of purchasing a Singapore residential property (HDB or private resale), with each cost line attributed to its funding source (cash, CPF or bank loan). Returns option fee, exercise fee, stamp duties (BSD and ABSD), downpayment breakdown, and a suffi
- calculate_hdb_resale_timeline: Generate a step-by-step dated timeline for an HDB resale purchase, from securing the Option to Purchase through to completion and key collection. Returns the ordered steps (what happens, the date, any payment due and its CPF/cash split), a summary (total payments, CPF and cash to
- calculate_private_resale_timeline: Generate a step-by-step dated timeline for a private (non-HDB) resale purchase, with the 1% option fee, 4% exercise payment, stamp duties and completion payment at the right steps. Exercise date defaults to 14 calendar days inclusive of the option date if not entered.
- calculate_progressive_payment: Model the monthly instalment profile of a Singapore Building Under Construction (BUC) property loan across progressive payment stages. Handles fixed and floating rate packages, per-stage cash/CPF/loan funding split, drawdown timing, rate stepping by year, and optional prepayments
