Supabase
Supabase’s official server lets AI create tables, query data and review project settings in your Supabase database.
Description from the maker (original English)
2025 HMDA FHA denial statistics and dated US mortgage rule tables, with verifiable receipts.
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.

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.

Supabase’s official server lets AI create tables, query data and review project settings in your Supabase database.
Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.
Read-only statistics over the complete 2025 US HMDA mortgage record (1,187,606 FHA credit decisions, reverse mortgages excluded) plus dated, machine-readable US mortgage rule tables, served to AI agents over MCP. Every figure returns with its period, population and program scope, a use contract, and a receipt that can be verified later.
The red line: every figure is a historical aggregate. This server never accepts borrower details and never returns an individual approval prediction.

Plain HTTP beside MCP: GET /server-card, GET /cite/ (receipted sentence in text, Markdown, HTML and BibTeX), GET /verify?r= (is this figure still current; if not, which correction superseded it).
A figure travels with a receipt such as ⟦FRC:national-fha-denial-rate-2025:22.1%:ebf6b00b:m2610⟧: claim id, value, the first eight hex characters of a hash of the claim object, and the channel and month it was issued through. /verify answers current, stale (corrected since; the correction is returned), hash-current-value-mismatch (the quoted value was edited) or unrecognized (this publisher never issued it). Conformance runs on every deploy and is published: https://financeratecalc.com/conformance.html
The frc-mcp npm package is the original five read-only tools from a bundled data snapshot; it does not carry the rule tables, the sentence gate or receipts. Prefer the remote endpoint.
