Overview

AI-generated overview

Remote MCP server exposing NOAA SWPC space weather data: current and forecast Kp, aurora chance at any location, alerts, flares and solar wind.

What you can do
  • Check current geomagnetic activity: Kp index now, storm level and recent 3-hourly values
  • Forecast geomagnetic storms for the next three days, with daily maxima and peak blocks
  • Estimate aurora probability overhead at a latitude and longitude, plus the best chance poleward
  • Read NOAA space weather scales for radio blackouts, radiation storms and geomagnetic storms
  • List official NOAA alerts, watches and warnings with verbatim message text
  • Review recent GOES X-ray flares, solar wind speed and the daily 10.7 cm solar flux
When to use it
Useful when someone asks whether a geomagnetic storm is under way, whether the northern or southern lights might be visible from a given place, or how space weather may affect HF radio, GPS, drones or aviation. Also handy for planning aurora trips and checking official storm warnings.
Requirements
A remote streamable HTTP endpoint; nothing to install locally. Works without credentials under a free daily allowance; an optional Authorization header with a bearer key raises the limit, and a free key is obtained from the provider's key endpoint.
Before you install
The optional Authorization bearer key is a secret and should be kept private. Forecasts are stated to be uncertain by hours and 1-2 Kp, and the solar flux value is a single daily figure, so results should not be treated as precise or safety-critical. All data comes from NOAA SWPC via the provider.

Installation

In SourceWeft

  1. Open UK Data: Space weather and aurora in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/uk.co.reliness%2Fspace-weather/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

kp_index_now

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)

Parametershours

kp_forecast_3day

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)

Takes no parameters.

aurora_chance_at_location

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)

Parameterslatlon

space_weather_scales

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)

Takes no parameters.

space_weather_alerts

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)

Parameterslimitsince_hours

solar_flares_recent

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)

Parametersdayslimitmin_class

solar_wind_speed

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)

Takes no parameters.

solar_flux_10cm

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)

Takes no parameters.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
