Quality & Safety
Based on automated analysis of tool definitions and protocol compliance.
Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

}🟢get_regions(level, country_iso3, limit)
List sub-national areas in the Cracks Index, ranked within their level. The index covers sub-national areas as well as countries: EU regions (NUTS-2) and Dutch municipalities. This tool returns those areas with their composite score and rank. Parameters ---------- level : optional Filter by area level: ``nuts2`` (EU regions) or ``gemeente`` (Dutch municipalities). Omit to return all sub-national areas. country_iso3 : optional ISO-3166 alpha-3 country code to restrict the list to one country's areas (e.g. ``NLD``). limit : optional Maximum number of areas to return (1-1000, default 200). Read-only, no personal data. Ranks are within the area's own level.

}🟢region_detail(region_code)
Return one sub-national area: score, rank, indicator breakdown and fix. Given a region code (an EU NUTS-2 code or a Dutch municipality CBS GM-code), returns that area's composite score, its rank within its own level (regions rank against regions, municipalities against municipalities), the per-indicator breakdown and the single highest-impact improvement for the area. Read-only, no personal data.
Input Schema
{
"type": "object",
"properties": {
"region_code": {
"description": "Area code of an EU NUTS-2 region or Dutch municipality, e.g. 'NL32' (Noord-Holland) or 'GM0363' (Amsterdam). Case-insensitive.",

}🟢improvement_guidance(area)
Return constructive improvement guidance for one area. Given an area identifier — an ISO-3166 alpha-3 country code, an EU NUTS-2 region code or a Dutch municipality CBS GM-code — returns that area's highest-impact improvement lever from the Cracks Index, together with Fynqo's approach to earlier, joined-up coordination and a link to the public "claim your score" page where an organisation can request a deeper local report. Read-only, no personal data. The lever is framed as "the change most associated with improvement". It is general, aggregated guidance, not policy, medical, legal or financial advice, and carries no promise of a guaranteed score gain (sales-engine §3.4, §5).
Input Schema
{
"type": "object",
"properties": {
"area": {

}🟢score_trends(area)
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. Read-only, area-level aggregates only, no personal data.
Input Schema
{
"type": "object",
"properties": {
"area": {
"description": "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.",

}Output Schema
{
"type": "object",
"additionalProperties": true,
"title": "score_trendsDictOutput"
}🟢top_movers(level, limit)
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, area-level aggregates only, no personal data.
Input Schema
{
"type": "object",

}🟢indicator_ranking(indicator_key, level, limit)
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.
Input Schema
{
"type": "object",
"properties": {
"indicator_key": {
"description": "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.",

],
"title": "indicator_rankingArguments"
}Output Schema
{
"type": "object",
"additionalProperties": true,
"title": "indicator_rankingDictOutput"
}🟢indicator_correlations(level)
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 the other; near -1 means the opposite. Read-only, area-level aggregates only, no personal data.
Input Schema
{
"type": "object",
"properties": {
"level": {
"default": "country",
"description": "Area level to correlate over: 'country', 'nuts2' (EU regions) or 'gemeente' (Dutch municipalities). Defaults to 'country'.",

},
"title": "indicator_correlationsArguments"
}Output Schema
{
"type": "object",
"additionalProperties": true,
"title": "indicator_correlationsDictOutput"
}🟢area_statistics(area)
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-level aggregates only, no personal data.
Input Schema
{
"type": "object",
"properties": {
"area": {
"description": "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.",

"title": "area_statisticsArguments"
}Output Schema
{
"type": "object",
"additionalProperties": true,
"title": "area_statisticsDictOutput"
}🟢gemeente_social_profile(region_code)
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 score. Read-only, no personal data. wmo_pressure and youth_care_load are context only — never folded into the score. CBS aggregates describe an area, not its quality. Netherlands-only: the deeper municipal layer exists for Dutch municipalities.
Input Schema
{
"type": "object",
"properties": {
"region_code": {
"description": "CBS GM-code of a Dutch municipality, e.g. 'GM0363' (Amsterdam) or 'GM0599' (Rotterdam). Case-insensitive.",

"title": "gemeente_social_profileArguments"
}Output Schema
{
"type": "object",
"additionalProperties": true,
"title": "gemeente_social_profileDictOutput"
}🟢compare_gemeenten(region_codes)
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 — shown but never scored. CBS aggregates describe an area, not its quality. Netherlands-only.
