Spec Driven Development
MCP Server that facilitates spec-driven development workflows, not just Vibe Coding.
Description from the maker (original English)
Current and past Australian bank rates: home loans, savings and term deposits, with lender and date.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

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.
find_productsFind current products by lender and words in the product name, e.g. institution "CBA" and query "standard variable". Returns institution_id and product_id for each match, with category, rate and observed_date. A product is the pair (institution_id, product_id): pass both to rate_
compare_ratesCurrent comparison across institutions for a product category (home_loan | savings | term_deposit | credit_card | personal_loan | car_loan | business_loan): each product at its own most recent observation (observedDate tells you how fresh). Home loans can be filtered by loanPurpo
rate_historyAdvertised rate history for one product (institutionId and productId). Returns each recorded rate, comparison rate and fees between two dates, with the date each was recorded. RateSonar's record starts 2026-06-12. Pass grid:true to also get `grid`, one point per day: status 'obse
rate_detailsExact CDR product-reference detail for one institution and product: every published lending or deposit rate entry and tier, with fees, features, eligibility, constraints, source quality flags, the date the version was recorded and the lender's own links. asOf returns the version
rate_changesRecent change-events, newest first: a rate moved, a product was added, or a product was withdrawn. Each event has the lender, the product's name and category, and field-level deltas (e.g. rate [6.09, 5.89], bps -20). Filter by institutionId, category, kind and direction. Returns
list_seriesEvery standard series slug the series tool accepts, with its label, kind (level or spread) and unit (% or bps). Call this before series when you do not know the slug.
seriesStandardized rate series: named LEVEL series (hl.var.oo.pi = headline variable home loan; sav.max; td.12m; biz.loan.var; cash = RBA cash rate…) and SPREAD series in bps (spread.hl.var-cash = lending pass-through; spread.hl.var-sav.max = the margin; spread.hl.var-hl.fix.36m = vari
bank_positionSelected bank deposit and loan contracts against matching peer brands, own recorded history, RBA cash and dated funding disclosures. Pass an institutionId and product cohort. No claims about private ALM, intent or margins.
bank_analysisAn evidence-checked AI reading of bank_position. Supports savings or term deposits against variable/fixed home loans, card purchase rates, personal, car or business loans. Returns cited claims, inference labels and dated records; partial readings name withheld sections; unavailab
yield_curveRBA curve nodes for an exact date or the latest publication: cash and bond yields as published, and the RBA's fitted zero, forward and discount curves (each point says whether it is observed or derived), with optional exact comparison date, instrument details, source digest and c
curve_pipeline_statusValidation, freshness, missing families, source hashes and last-good fallback status of the automated curve pipeline. An unhealthy response is evidence of a pipeline problem, not bank risk.

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 2 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 (0.1.0) reached the registry 7 days ago.
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.
