What it can do

Tool names and descriptions exactly as the server reported them on Nov 12, 2026. The maker wrote them, not us; we show them as plain text.

  • find_products

    Find 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_rates

    Current 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_history

    Advertised 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_details

    Exact 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_changes

    Recent change-events, newest first: a rate moved, a product was added, or a product was withdrawn.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_series

    Every 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.

  • series

    Standardized 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_position

    Selected 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_analysis

    An 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_curve

    RBA 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_status

    Validation, 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.

Common questions

Is RateSonar safe?

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.

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 (0.1.0) reached the registry 14 days ago.

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 on the web (full MCP on Business and above; Pro read-only).

What can I use instead?
