# spaceweather-mcp

<!-- mcp-name: io.github.hoon1983/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](https://github.com/hoon1983/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).

## Tools

**NOAA SWPC** (public domain)
| Tool | Returns |
| --- | --- |
| `get_conditions_now` | One-call snapshot: Kp, Bz/Bt, wind speed/density, G/S/R, storm flag, summary |
| `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)

## Run

```bash
uv run spaceweather-mcp        # stdio MCP server
uv run pytest                  # tests
```

Add to `claude_desktop_config.json` (after publishing to PyPI):

```json
{ "mcpServers": { "spaceweather": { "command": "uvx", "args": ["spaceweather-mcp"] } } }
```

- **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.
