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).

Tools

NOAA SWPC (public domain)

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

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

• NASA DONKI via CCMC (kauai.ccmc.gsfc.nasa.gov/DONKI) — U.S. public domain (no API key needed). Credit NASA/CCMC DONKI.
• USGS Geomagnetism (geomag.usgs.gov) — U.S. public domain. Credit the U.S. Geological Survey. (Sourced directly from USGS, not via INTERMAGNET, to keep public-domain status.)
• 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.
