spaceweather-mcp
A Model Context Protocol server for space weather and geomagnetic conditions — solar flares, the solar wind, geomagnetic storms (Kp/Dst), radiation storms, sunspot regions, aurora forecasts, and a catalogued event history — so an AI agent can answer "what's the sun/space weather doing right now, and will I see aurora?" from authoritative data.
Sibling to seismic-mcp: that one reconciles earthquakes across agencies; this one reports solar/geomagnetic conditions. They install side by side.
Status
15 tools across 4 data sources — all live and verified. Everything is U.S./NASA public domain except the Kyoto Dst index, which is non-commercial and clearly labeled (and kept segregated from the public-domain feeds).
NOAA SWPC (public domain)
| Tool | Returns |
|---|

get_kp_index | Observed planetary Kp series (~1 week) |
get_kp_forecast | NOAA 3-day Kp forecast |
get_solar_wind | L1 magnetic field + plasma (window: 1-day/7-day) |
get_alerts | Recent SWPC alerts/watches/warnings |
get_noaa_scales | G/S/R scales for today + 3 days |
get_27day_outlook | Daily F10.7 flux, Ap, largest Kp for 27 days |
get_solar_flares | Recent GOES X-ray flares (C/M/X class events) |
get_radiation_storm | Current proton flux + NOAA S-scale (radiation storm) |
get_solar_regions | Today's sunspot regions + C/M/X flare probabilities |
get_aurora_forecast | OVATION aurora probability (pass lat/lon for a local %) |
NASA DONKI (public domain) — get_space_weather_events (CME / GST / FLR / SEP / IPS / HSS event catalog)
USGS Geomagnetism (public domain) — list_observatories, get_observatory (magnetometer X/Y/Z/F)
Kyoto WDC (non-commercial) — get_dst (hourly disturbance storm-time index)

- Kyoto WDC for Geomagnetism — Dst index, non-commercial use only: acknowledge "WDC for Geomagnetism, Kyoto", cite the Dst DOI; real-time values are provisional. The non-commercial restriction is documented in the
get_dst tool description and the DstReading schema (both surfaced to MCP clients), and this feed is kept separate from the public-domain ones.
⚠️ Only the Kyoto Dst feed is non-commercial. It is segregated, and its non-commercial terms are stated in the tool/schema docs the client sees, so a downstream commercial user is not silently bound by those terms.
Deliberately not included: INTERMAGNET and SILSO sunspot number (both CC BY-NC — would taint the otherwise commercially-usable server); JPL Horizons ephemeris (different domain). F10.7 is available via get_27day_outlook; GFZ Hp30/Hp60 high-cadence indices (CC BY 4.0) are a possible future add.
Safety
Informational only. Not for operational decisions affecting power grids, aviation, satellites, or human safety — consult official NOAA SWPC products for those. Real-time values are preliminary and routinely revised.
