Nothing to run from here
The Cracks Index is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http the-cracks-index-mcp https://api.fynqo.app/mcp/cracks/
# 2 — ask your agent for something these tools do
# get_cracks_index, compare_countries, country_detail and 12 more
The Cracks Index costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http the-cracks-index-mcp https://api.fynqo.app/mcp/cracks/Reconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.

Return the index methodology: indicators, weights, direction, sources.
No parameter schema on file.
Return one area's composite-score history across every snapshot. Given an area identifier — an ISO-3166 alpha-3 country code, an EU NUTS-2 region code or a Dutch municipality CBS GM-code — walks every published Cracks Index snapshot and returns that area's composite score and rank at each point in time, plus the net change from the first to the most recent snapshot.

| area | string | yes | An ISO-3166 alpha-3 country code (e.g. 'NLD') or an area code of an EU NUTS-2 region or Dutch municipality (e.g. 'NL32', 'GM0363'). Case-insensitive. |
Return the biggest risers and fallers between the two latest snapshots. Compares every area's composite score in the most recent snapshot against the snapshot before it and returns the areas that improved most (`improvers — score fell) and worsened most (decliners` — score rose). Needs at least two snapshots; returns an explanatory empty payload otherwise. Read-only
| Parameter | Type | Required | Notes |
|---|---|---|---|
| level | string | no | Area level to rank movers within: 'country', 'nuts2' (EU regions) or 'gemeente' (Dutch municipalities). Defaults to 'country'. |
| limit | integer | no | How many risers and how many fallers to return each (1-50, default 5). |
Rank all areas by a single chosen indicator. Returns every area's value for one indicator, ordered best-first by the direction-corrected `normalized_score` (a higher normalised score always means fewer cracks on that indicator). The raw value and unit are included so the figure can be quoted directly. Read-only, area-level aggregates only, no personal data.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| indicator_key | string | yes | One of the six Cracks Index indicators: 'problem_debt', 'eviction_rate', 'mh_treatment_gap', 'youth_care_unmet', 'food_insecurity' or 'material_deprivation'. See the 'methodology' tool for definitions |

| limit | integer | no | Maximum number of areas to return (1-500, default 200). |
Return pairwise correlations between the six indicators across areas. Computes the Pearson correlation coefficient between every pair of the six Cracks Index indicators, using each area's direction-corrected normalised score. Adds a short plain-language note naming the strongest relationship. A coefficient near +1 means areas that do well on one indicator tend to do well on th
| Parameter | Type | Required | Notes |
|---|---|---|---|
| level | string | no | Area level to correlate over: 'country', 'nuts2' (EU regions) or 'gemeente' (Dutch municipalities). Defaults to 'country'. |
Return where one area sits statistically within its own level. Places an area against its peer group (all areas at the same level in the latest snapshot): its percentile, the distance from its composite score to the level median, best and worst, and the handful of areas nearest to it by score. Useful for answering "is this area typical, or an outlier?". Read-only, area-le

| area | string | yes | An ISO-3166 alpha-3 country code (e.g. 'NLD') or an area code of an EU NUTS-2 region or Dutch municipality (e.g. 'NL32', 'GM0363'). Case-insensitive. |
Return the Dutch social-domain profile for one municipality. Given a CBS GM-code, returns that municipality's four v1 social-domain indicators — social-assistance receipt, modelled homelessness, Wmo use and youth-care use — each with its raw value, source and whether it was measured or modelled. The composite score and rank are included for context, alongside the v0-equivalent
| Parameter | Type | Required | Notes |
|---|---|---|---|
| region_code | string | yes | CBS GM-code of a Dutch municipality, e.g. 'GM0363' (Amsterdam) or 'GM0599' (Rotterdam). Case-insensitive. |
Compare the social-domain profile of several Dutch municipalities. Given two to six CBS GM-codes, returns a side-by-side comparison of their four v1 social-domain indicators plus composite score and rank. Useful for an agent answering "how does municipality A compare to B on the social domain". Read-only, no personal data. wmo_pressure and youth_care_load are context only

Release 0.1.2 · scanned 20 Oct 2026
Graded from the tools this server lists, not from its source code.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish The Cracks Index can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
