What DMI Open Data (BYOK) is for

DMI Open Data (BYOK) lets an AI assistant read your own DMI Open Data data through the DMI Open Data API with a key you supply (DMI Open Data API key). Read-only: 7 tools (list_weather_stations, get_weather_observations, list_climate_stations, get_station_climate_values, get_municipality_climate_values, get_country_climate_values, get_grid_climate_values). The BYOK key travels with each request, is used for that one call only and is never stored, logged or cached; it is only ever sent to dmigw.govcloud.dk. Unofficial connector by Unify Dynamics LLC: not affiliated with, endorsed by or sponsored by DMI Open Data. DMI Open Data and its logos are trademarks of their owners and are used only to say which service the connector works with.

Ask your assistant things like:

• "Which active DMI weather stations are around Copenhagen?"
• "What is the latest temperature at station 06180?"
• "Which climate stations does DMI have in Greenland?"
• "What was the daily mean temperature at station 05185 in October 2026?"
• "What was the mean temperature in Copenhagen municipality (0101) by month in 2025?"
• "What was Denmark's mean temperature each year since 2000?"

What it does

• list_weather_stations: List DMI weather stations with id, name, type, country, status, height and measured parameters; filter by status, type or bounding box.
• get_weather_observations: Get recent meteorological observations (10-minute and hourly values) for a station and parameter, newest first by default.
• list_climate_stations: List DMI climate stations (used for daily, monthly and yearly statistics) with id, name, type, country and status.
• get_station_climate_values: Get aggregated climate values (hourly, daily, monthly or yearly) for one station and parameter such as mean_temp.
• get_municipality_climate_values: Get aggregated climate values for a Danish municipality by four-digit municipality id.
• get_country_climate_values: Get aggregated climate values for the whole country (Denmark) for a parameter and period.
• get_grid_climate_values: Get aggregated climate values for a 10 km grid cell of the Danish national grid.

BYOK key

You bring your own DMI Open Data DMI Open Data API key (https://www.dmi.dk/friedata/). Your assistant sends it in the X-Upstream-Key header with each request. ConnectorBay uses it for that one call only: it is never stored, logged or cached, never shown in an answer, and it is only sent to dmigw.govcloud.dk over https, with no redirects followed. Create a key with the fewest permissions the tools need (read-only if the provider offers it), and revoke it at the provider whenever you like.

Data sources

• https://opendatadocs.dmi.govcloud.dk/en/APIs/Meteorological_Observation_API (the API this connector calls, with a BYOK key)

Live from the DMI Open Data API (dmigw.govcloud.dk) with a BYOK key; documentation: https://opendatadocs.dmi.govcloud.dk/en/APIs/Meteorological_Observation_API. Endpoints checked against that documentation on 2026-10-16.

DMI Open Data (BYOK) — Privacy Policy

Effective 24 October 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What DMI Open Data (BYOK) is. DMI Open Data (BYOK) is a connector (an MCP server and REST API) that an AI assistant calls on your behalf to read your own DMI Open Data data: Read Danish Meteorological Institute weather station lists, observations and climate statistics for Denmark and Greenland with your own API key. You bring your own DMI Open Data DMI Open Data API key; the assistant sends it to us with each request.

BYOK key. The key you supply is used to make the one DMI Open Data call you asked for. Our application does not store it, write it to a log, put it in a cache, or share it. It is sent only to dmigw.govcloud.dk, over https, and is removed from any text we return to you or your assistant. We do not follow redirects with your key. If DMI Open Data rejects it, we say so without repeating it.

What we receive. The arguments of each tool call, the BYOK key (for that call only), the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant) and standard server logs. What DMI Open Data receives. The request we make on your behalf, including the key and the arguments, under DMI Open Data's own terms and privacy policy. DMI Open Data acts at your direction and is the only recipient of the data of your request besides our hosting provider.

What we return. The answer DMI Open Data gives for your request, trimmed to the fields the tool documents. We do not keep it: it is returned to your assistant and not stored, cached or used to train anything.

What we do not do. We do not build a profile, sell or share personal information, or keep your DMI Open Data data. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting access logs (IP addresses, request paths and status codes) are kept for up to 30 days for security and abuse prevention; our application adds no request headers or bodies to them.

Sub-processors. DMI Open Data (the API you call with a BYOK key, at your direction). Hosting: Vercel (United States regions).

Your rights. Because we store no personal data beyond short-lived logs, requests to access, correct or delete data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. Revoke your key at DMI Open Data at any time to end all access.

Children. DMI Open Data (BYOK) is a general-audience service operated by the adult using the assistant, under DMI Open Data's own age rules.

Changes. We will post changes here with a new effective date.
