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_city(slug)
Get base data for a German city (population, area, coordinates). Sourced from Wikidata. Read-only. Useful as a first lookup to confirm a city exists and get its core attributes. For a broader question about the city (what data is available at all) use ``get_city_overview`` instead.
Input Schema
{
"type": "object",
"properties": {
"slug": {
"description": "City identifier, e.g. 'berlin' or 'hamburg'. Resolved leniently: the German name with or without umlauts, any casing, a common English exonym or short form also works (München/munich/munchen -> muenchen, cologne -> koeln, frankfurt -> frankfurt-am-main). An unknown name returns 404 with a 'Meintest du ...?' suggestion. list_cities gives the canonical slugs.",

}🟢get_city_overview(slug)
Get a ONE-CALL overview of everything InfraNode knows about a German city. Start here for any city question. Returns: the city's base data, a CATALOG of all 81 available data types (weather, air quality, public transit, trains, traffic, charging, parking, solar, energy, demographics, taxes, accidents, tourism, heritage, trees, population density, playgrounds, post boxes and many more), each with its coverage status and the exact tool to call next (for most data types that is ``get_city_resource(slug, resource=<type>)``), plus a small live highlights snapshot (current weather, air quality and train departures). Data types not yet covered for this city show where they ARE available so you can pivot. InfraNode keeps adding data and cities, so the catalog grows over time. Read-only.

}🟢get_city_resource(slug, resource)
Fetch ANY per-city data type by its key (generic accessor, 81 data types). One tool for the whole breadth of InfraNode: live data (air, traffic, transit stops, parking, charging, water-level, flood, sharing, fuel-prices, webcams, station-departures/-arrivals/stations, ...), statistics (demographics, unemployment, tourism, accidents, crime-stats, indicators, land-values, tax-rates, insolvencies, ...), multi-year TIME SERIES (``sustainability``: SDG indicators per municipality, one value per year from 2006 to 2023, so trends can be answered without stitching snapshots), infrastructure and environment (solar, solar-roofs, district-heating, energy, heritage, tree-cadastre, playgrounds, public-toilets, markets, education, ...) and more. Discover the valid keys and per-city coverage with ``get_city_overview(slug)`` or the ``infranode://catalog`` resource; the ``resource`` enum lists every key. Uncovered types return ``source_status="not_covered"`` (plus where they ARE available), never an error. Read-only.

Get live public-transport departures with real-time delays for a stop. Sourced from GTFS-RT/HVV/VGN. Unlike the static stop list (``get_city_resource(slug, resource='transit')``), this returns minute-fresh departures including delay for ONE stop.

Compare ONE resource across MULTIPLE cities in a single response. Fans the resource out over the listed cities and returns a per-city ``source_status`` (ok/disabled/no_data/error/not_found), so a missing or failing city source does not spoil the whole answer. Read-only.
