Nothing serious here today
Today is the operative word: we check UK Data: Space weather and aurora every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Read directly from the server with tools/list, grouped by what they act on.
If a tool disappears, we record the date.
solar
solar_flares_recent
Was there a big solar flare today? Lists X-ray flares detected by the GOES satellites in the last 1-7 days, newest first, with class (A, B, C, M, X), begin, peak and end times, peak flux and the NOAA radio blackout level implied, plus the largest flare in the period. From NOAA SWPC. It covers flares only, not CMEs or whether a flare will affect Earth. (cost: 1 credit)
solar_flux_10cm
What is the solar flux index today? Returns the latest daily 10.7 cm solar radio flux (F10.7, in solar flux units), the standard solar activity measure radio amateurs use for HF band conditions, from NOAA SWPC, with a rough HF conditions guide. It is a single daily value; actual propagation also depends on Kp, time of day and season. (cost: 1 credit)
solar_wind_speed
How fast is the solar wind right now? Returns the latest solar wind speed in km/s measured upstream of Earth, from NOAA SWPC, with a plain-language level (slow, moderate, fast, very fast). Aurora chasers use it to judge whether a CME or high-speed stream has arrived. Each answer gives the age of the reading and flags it as stale when it is over 30 minutes old, as the NOAA summary feed sometimes lags by hours. It does not include the magnetic field direction (Bz), which also matters for aurora. (cost: 1 credit)
space
space_weather_alerts
Is there a solar storm warning? Returns the latest official NOAA SWPC alerts, watches and warnings (geomagnetic storm watches, K-index warnings, flare and proton alerts) with type, headline, issue time and the verbatim message text. Useful for newsrooms and enthusiasts who need the official wording. The feed covers roughly the last few days only. (cost: 1 credit)
space_weather_scales
How bad is space weather right now? Returns the current NOAA space weather scales for radio blackouts (R), solar radiation storms (S) and geomagnetic storms (G), the maximum of the past 24 hours, and NOAA SWPC probabilities for the next 3 days. Useful for HF radio users, pilots, drone and GPS users, satellite and grid operators and journalists. It gives levels and probabilities, not impact assessments for a specific system. (cost: 1 credit)
aurora
aurora_chance_at_location
Can I see the northern (or southern) lights from here right now? Returns the probability of aurora overhead at a latitude and longitude from the NOAA SWPC OVATION model, a 30-90 minute forecast, plus the best chance within 5 degrees poleward (aurora there can show on the horizon). Works worldwide. It does not account for daylight, cloud or moonlight, and is not a multi-day forecast. (cost: 1 credit)
forecast
kp_forecast_3day
Will there be a geomagnetic storm in the next few days? Returns the NOAA SWPC predicted Kp for each 3-hour block over the next 3 days, the daily maximum, the peak block and any G-scale storm expected. For planning aurora trips and checking storm watches. Forecasts are uncertain by hours and 1-2 Kp; observed values are in kp_index_now. (cost: 1 credit)
index
kp_index_now
What is the Kp index right now? Returns the current planetary Kp (0-9), its storm level (G1-G5 if any) and the 3-hourly values for the last 24 hours (or up to 7 days), from NOAA SWPC. Useful for aurora chasers, radio amateurs and anyone asking whether a geomagnetic storm is under way. It reports observed activity only; use kp_forecast_3day for the coming days. (cost: 1 credit)

UK Data: Space weather and aurora — questions
Answers built from our own checks of this server.
What can UK Data: Space weather and aurora do?
It exposes 8 tools, read directly from the server on our last check. Among them: aurora_chance_at_location, kp_forecast_3day, kp_index_now, solar_flares_recent, solar_flux_10cm, solar_wind_speed and 2 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
What is UK Data: Space weather and aurora mostly used for?
Its tools cluster around solar and space. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is UK Data: Space weather and aurora working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 75 of 75 checks got a reply (100.0%), average response time 233 ms. The bar chart above shows every period we have measured.
How do I connect UK Data: Space weather and aurora?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does UK Data: Space weather and aurora need an API key?
No. UK Data: Space weather and aurora completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is UK Data: Space weather and aurora?
It answers our handshake in 233 ms on average, which is faster than 62% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
