solar-mcp
MCP server for space weather and HF propagation conditions — live solar flux, Kp index, DSCOVR solar wind, X-ray flux, alerts, 27-day forecast, and band-by-band outlook through any MCP-compatible AI assistant.
Part of the qso-graph project. No authentication required — all data from NOAA SWPC public endpoints.

| Tool | Description |
|---|---|
solar_conditions | Current SFI, Kp, and NOAA R/S/G space weather scales |
solar_forecast | 27-day SFI and Kp forecast from NOAA |
solar_alerts | Active space weather alerts and warnings |
solar_wind | Real-time DSCOVR L1 solar wind (Bz, speed, density) |
solar_xray | GOES X-ray flux and solar flare classification |
solar_band_outlook | HF band-by-band propagation assessment (160m-6m), each band rated on the scale in BAND-OUTLOOK.md |
get_version_info | Service version + upstream spec version (fleet identity attestation) |

"What are the current solar conditions?"
"Is the solar wind causing any geomagnetic disturbance?"
"What's the 27-day solar forecast look like?"
"Are any bands open right now on HF?"
"Are there any active space weather alerts?"
"What class solar flare is happening?"
Data Sources
Every value comes from a public NOAA Space Weather Prediction Center endpoint at services.swpc.noaa.gov:
| Data | Endpoint | Used by |

| Planetary K-index | /products/noaa-planetary-k-index.json | solar_conditions, solar_band_outlook |
| NOAA R/S/G scales | /products/noaa-scales.json | solar_conditions |
| Space weather alerts | /products/alerts.json | solar_alerts |
| 27-day outlook | /text/27-day-outlook.txt | solar_forecast |
| Solar wind (real-time, 1 minute) | /json/rtsw/rtsw_wind_1m.json, /json/rtsw/rtsw_mag_1m.json | solar_wind |
