api record

This server is stateless and does not remember prior calls. A recommendation is only valid for the exact inputs of the request that produced it. If the borrower changes ANY input or preference — deal kind, current bank, property type/status, loan amount, rate-type preference, or any free-text priority — you MUST call `recommend_packages` again with the full, updated input set. Never adjust, re-rank, or re-explain a previous response from memory; always issue a fresh call. Before calling `recommend_packages`, gather the core deal facts and ask for any that are missing rather than guessing:…

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • list_market_indices open 1h ago

    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`.

  • list_banks open 1h ago

    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.

  • calculate_package_schedule unknown never probed

    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_mortgage_repayment` instead. Pass a `packageId` from `recommend_packages`, plus `loanAmount` and `tenureYears`. Always returns the full canonical schedule: loan facts (`context`), the per-tier breakdown (`periods`), rate structure, totals, and the per-year schedule (`annual`). The month-by-month schedule (`monthly`) is empty unless you pass `includeMonthly: true`. To also generate downloadable files, pass `formats` (`["pdf"]`, `["xlsx"]`, or both) — the public URLs come back under `documents` (null otherwise). Optional `firstPaymentDate` (YYYY-MM-DD, defaults to next month) dates the schedule.

  • recommend_packages unknown never probed

    Rank Singapore mortgage packages for a borrower. Returns up to 3 LLM-ranked picks with per-package reasoning, the 3 lowest-rate options, and a lookup of full package details. Core inputs (gather these first; ask the borrower if missing — do not guess): `dealKind` (PURCHASE | REFINANCE); `currentBankId` (required only for REFINANCE — use `list_banks` to resolve the lender name into its UUID); `propertyType` (HDB | PRIVATE | COMMERCIAL); `propertyStatus`; `loanAmount`. `propertyStatus` depends on `propertyType` — only these pairings are valid: HDB → COMPLETED (resale) or BTO (Build-To-Order, new); PRIVATE → COMPLETED (ready-built) or BUC (Built-Under-Construction, new); COMMERCIAL → OWNEROCCUPIED, INVESTMENT or PERSONAL. Do not mix across types (e.g. HDB + BUC or PRIVATE + BTO are invalid). Optional inputs (only refine the ranking): `ratesType` (FIXED | FLOATING) and `userContext` (free-text borrower priorities, timeline, bank relationships, citizenship, etc.). Pass `formats: ["pdf"]` to also generate a one-page comparison document of the recommended set (with per-package verdicts); the download URL comes back under `documents`. Optional `tenureYears` (default 25) sets the document's instalment assumptions. Stateless: if any input or preference changes, call this tool again with the full updated set — never infer an updated answer from a previous response.

  • compare_packages unknown never probed

    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` from `recommend_packages`, plus `loanAmount` and optionally `tenureYears` (default 25). `dealKind`/`propertyType`/`propertyStatus` only label the report header. Pass `formats: ["pdf"]` to also render the one-page comparison document — the download URL comes back under `documents.pdfUrl` (null otherwise). This comparison has no verdict/recommendation section by default because it carries no borrower context; for a personalised ranking with verdicts, use `recommend_packages` (optionally with `formats`). The optional `verdicts`/`recommendedId` inputs only carry over the reasoning from a prior `recommend_packages` call — never author them.

  • get_property_valuation unknown never probed

    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 (`propertyTypeUsed` in the result tells you which). A `valued: false` result means SPML could not value the unit — that is a valid answer, not an error.

  • check_eligibility unknown never probed

    Run the regulatory affordability gate for up to four 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 loan, the income-weighted average age (IWAA), and the maximum loan under both HDB/EC and private property rules. Use this upstream of `recommend_packages` to confirm what a borrower can qualify for.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id d117b0300e9908db.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/d117b0300e9908db/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/d117b0300e9908db/badge.svg)](https://brick.blue/agent/d117b0300e9908db?ref=badge)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
