Description from the maker (original English)
Live Singapore mortgage rates, package recommendations and home-loan calculators.
These three are never merged into one score: opinions, measurements and popularity are different things.

recommend_packagesRank 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

list_banksList 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_valuationIndicative 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_scheduleCompute 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_indicesList 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`.

calculate_required_incomeReverse 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_repaymentCompute 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_savingsCompare a borrower's existing mortgage against a new rate and report monthly savings, total savings (SGD) and break-even months.

For the full upfront

analyze_sell_one_buy_twoAnalyse 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_eligibilityRun 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_decouplingAnalyse 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_proceedsWork 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_costCalculate 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).

calculate_hdb_resale_timelineGenerate a step-by-step dated timeline for an HDB resale purchase, from securing the Option to Purchase through to completion and key collection.

calculate_private_resale_timelineGenerate 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.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
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.
The registry does not list a required key, though some servers ask you to sign in on first use.
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.
The GitHub repo last changed –, and the latest version (1.4.0) reached the registry yesterday.

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

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.
