No: the server works without sign-in

Keyless remote MCP server for German public-infrastructure open data: weather, air quality, traffic, public transit (incl. live departures), parking, roadworks, charging, water levels, energy, statistics and more for 84 German cities. Data normalized from official sources (DWD, Umweltbundesamt, Mobilithek, GovData). 12 lean read-only tools covering 64 data types. Apache-2.0.

How to connect

How to connect InfraNode to Claude

The server address to paste into Claude settings:

https://infranode--infranode.run.tools

  1. Open Claude (claude.ai or the desktop app).
  2. Go to Settings → Connectors.
  3. Click Add custom connector.
  4. Paste the server address copied below into Remote MCP server URL and click Add.
  5. In a chat, click + → Connectors and switch the new connector on.

Custom connectors are available on Free, Pro, Max, Team and Enterprise plans (Free is limited to one). On Team and Enterprise an organization Owner adds the connector first under Organization settings → Connectors.

Authorization

After you click Add, a sign-in window for the service opens. Sign in with your own account and approve access. Claude never sees your password.

How to connect InfraNode to ChatGPT

The server address to paste into ChatGPT settings:

https://infranode--infranode.run.tools

  1. Open ChatGPT in a browser (chatgpt.com). A Plus, Pro, Business, Enterprise or Edu plan is required.
  2. Turn on developer mode once: Settings → Apps → Advanced settings → Developer mode.
  3. Open Settings → Connectors and click Create.
  4. Fill in the form: Name (anything), Description (one line about what the service does), MCP server URL (copy it below).
  5. Under Authentication choose OAuth if the service requires sign-in, otherwise None. Click Create.
  6. In a new chat open + → Apps/Connectors and enable the connector.

OpenAI has renamed this section before (Connectors → Apps/Plugins). If the label differs, search settings for "developer mode". On Business/Enterprise workspaces an admin must allow custom connectors first.

Authorization

On first use ChatGPT opens the service's sign-in window. Sign in and approve access.

How to connect InfraNode to Cursor

The server address to paste into Cursor settings:

https://infranode--infranode.run.tools

Fastest: click Open in Cursor below and confirm the prompt.

Manually:

  1. In Cursor open Settings → Cursor Settings → MCP and click Add new global MCP server.
  2. Paste the JSON copied below into ~/.cursor/mcp.json (per project: .cursor/mcp.json in the repo root).
  3. Save the file. The server appears in the MCP list; authorize it there if asked.

Authorization

If the service needs sign-in, an authorize button appears next to the server in the MCP list.

Server tool list (12)

Raw names from tools/list. Only developers need these.

get_cityGet 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_overviewGet 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 ~60 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_resourceFetch ANY per-city data type by its key (generic accessor, ~60 data types). One tool for the whole breadth of InfraNode: live data (air, traffic, transit stops, parking, charging, water-level, flood, sharing, fuel-prices, icu-live, webcams, station-departures/-arrivals/stations, ...), statistics (demographics, unemployment, tourism, accidents, crime-stats, indicators, land-values, tax-rates, insolvencies, ...), 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.
air_qualityGet 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.
weatherGet 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.
poisGet points of interest in a German city, filtered by type. Sourced from OpenStreetMap. Read-only.
station_board_departuresGet 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.
station_board_arrivalsGet 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.
transit_departuresGet 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.
list_citiesList 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.
sourcesList 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.
compareCompare 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.
