What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

  • recommend_packages

    Rank live Singapore mortgage packages for one borrower and loan. Returns `recommended` (up to 3 picks with `reasoning`), `lowestRateIds` (cheapest eligible first), `isPersonalised` and `packages` (full details by id). Required: `dealKind` (PURCHASE | REFINANCE), `propertyType` (H

  • compare_packages

  • list_banks

    List active banks and lenders (id and name), sorted by name. Use it to resolve a borrower's current lender to the `currentBankId` that `recommend_packages` requires for refinance deals. Not a rate source.

  • get_property_valuation

    Indicative valuation (SGD) for a Singapore residential unit from an external valuation source. Requires `postalCode` and `unitNumber` in FF-SS format (e.g. "04-02"). `propertyType` ("Condo" or "HDB") and `areaSqft` are optional; without `propertyType` both are tried and `property

  • calculate_package_schedule

    Compute the amortisation schedule for a specific mortgage package using that package's real effective rates. Returns loan facts (`context`), the per-tier breakdown (`periods`), rate structure, totals and the per-year schedule (`annual`). Required: `packageId` from `recommend_pack

  • 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` from `list_market_indices`. Optional `startDate`/`endDate` (YYYY-MM-DD) narrow the range; results are paginated, newest first. Quote `rate` values are decimal fractions (0.

  • calculate_affordability

    Estimate the maximum loan and property price (SGD) a borrower can afford from monthly income, existing debt commitments and tenure, applying Singapore TDSR/MSR limits. Use this when you know the income and want the budget; for the income a target price needs, use `calculate_requi

  • calculate_required_income

    Reverse affordability: work out the gross monthly income (SGD) needed to support a target property price under Singapore TDSR/MSR limits. Use this when you know the target price; for the budget a known income supports, use `calculate_affordability`.

  • calculate_mortgage_repayment

    Compute the monthly repayment, total interest and total cost (SGD) for a hypothetical loan from a loan amount, tenure and an interest rate you supply (standard amortisation). Use this for what-if rates; for the real rates of a specific package, use `calculate_package_schedule` in

  • calculate_refinance_savings

    Compare a borrower's existing mortgage against a new rate and report monthly savings, total savings (SGD) 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

  • calculate_residential_stamp_duty

    Compute Buyer's Stamp Duty (BSD) and Additional Buyer's Stamp Duty (ABSD) in SGD for a Singapore residential purchase, given the price or value, buyer type (singaporean | pr | foreigner | entity | trust) and the number of residential properties already owned. For the full upfront

  • calculate_rental_stamp_duty

    Compute the Singapore stamp duty (SGD) payable on a property lease or tenancy from the rent and lease term. Not for purchases: use `calculate_residential_stamp_duty` for BSD and ABSD.

  • calculate_mortgage_stamp_duty

    Compute the Singapore stamp duty (SGD) payable on a mortgage or loan facility from the loan amount. Not for purchases: use `calculate_residential_stamp_duty` for BSD and ABSD.

  • calculate_seller_stamp_duty

    Compute Singapore Seller's Stamp Duty (SSD, in SGD) from the sale price or value and how long the residential property has been held. For net cash from a sale, use `calculate_sales_proceeds`.

  • 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, where one co-owner of a Singapore property transfers their share to the other: the seller's cash proceeds (after loan, CPF refund, SSD and legal fees), the buyer's financing of the share, BSD and ABSD, and the cost of each option for a planned next purchase. A

  • 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

Common questions

Is Cashew safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.4.0) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, First Sale Scout

Cashew

Give your agent Singapore's mortgage brain.

Cashew's MCP server exposes our live rate engine as callable tools, the same engine behind cashew.sg. Rank real bank packages, run stamp-duty and affordability maths, and model restructuring plays, all from inside your own agent.

Every figure is computed against bank rates synced daily, the same numbers Cashew shows its own customers. All major Singapore banks. HDB, private and commercial. Fixed and floating (SORA).

What it does

  • Find the best loan packages. Rank live packages from all major Singapore banks for any borrower profile, sorted by the real first-year rate.
  • Calculate the mortgage maths. Monthly repayment, total interest, affordability and the income a target loan needs, returned in a single call.
  • Run any scenario. From refinancing savings to every IRAS stamp duty, the maths is built in.
  • Plan the bigger moves. Decoupling and sell-one-buy-two, costed end to end with valuations on tap.

Connect

Add the server to Claude Desktop, Cursor, or any MCP-compatible client. There's no key to paste.

{

"mcpServers": { "cashew": { "url": "https://www.cashew.sg/mcp" } } }

Using Claude Code? Install it as a plugin instead:

claude plugin marketplace add cashew-sg/cashew-mcp

claude plugin install cashew-mcp@cashew

Then ask your agent something like: *"Should I refinance my $640k OCBC loan at 3.1%? I have 22 years left."*

Two tools, recommend_packages and get_property_valuation, ask you to sign in with your Cashew account the first time you use them. Everything else works straight away.
