## Quality 91/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth

### tool hygiene: 100 (weight 30)

- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema
- pass `tools.annotations`: 12 of 12 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 2,994 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 12, about 2,994 tokens to load them all
- tool set hash: 8de92e9ff5559acdf9113026e092040e
- badge: [![protogrid quality](https://protogrid.dev/badge/dev.infranode/infranode.svg)](https://protogrid.dev/servers/dev.infranode/infranode)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (12)

- `air_quality`: Get official air quality for a German city (PM10, NO2 and more).

Sourced from the Umweltbundesamt (UBA). Read-only. For live nearest-station
hourly readings use ``get_city_resource(slug, resource='air')`` instead.

- `compare`: 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.

- `get_city`: 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.

- `get_city_overview`: 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`: 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.

- `list_cities`: List all covered cities (slug, federal state, population, coverage).

Takes no arguments. Call this first to discover valid city slugs before
invoking any city-scoped tool. Read-only.

- `pois`: Get points of interest in a German city, filtered by type.

Sourced from OpenStreetMap. Read-only.

- `sources`: List all data sources with license, attribution and availability.

Takes no arguments. Shows which upstream sources InfraNode bundles and
whether each is currently active. Read-only.

- `station_board_arrivals`: Get live arrivals for ANY railway station by its EVA number.

Mirror of ``station_board_departures`` for arriving trains (all categories,
real-time delays, disruption messages). Get the EVA from
``get_city_resource(slug, resource='stations')``. Read-only.

- `station_board_departures`: Get live departures for ANY railway station by its EVA number.

Covers all train categories including local/regional (S/RB/RE) and long
distance, with real-time delays, cancellations and disruption messages. Get
the EVA from ``get_city_resource(slug, resource='stations')``. Read-only.

- `transit_departures`: 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. A ``stop_id`` is required: fetch the
city's transit stops first to discover valid stop IDs, then pass one here.
Read-only.

- `weather`: Get current weather observations for a German city.

Sourced from the Deutscher Wetterdienst (DWD): temperature, wind,
precipitation and related fields. Read-only, current conditions only (not a
forecast). For warnings use ``get_city_resource(slug,
resource='weather-warnings')``. For a broader question about the city (not
just weather) use ``get_city_overview`` instead, which already includes a
live weather highlight.
