About
Space weather & geomagnetic conditions (NOAA SWPC, NASA DONKI, USGS, Kyoto) via MCP.
Security Report
A well-designed space-weather MCP server with clean, maintainable code and appropriate security controls. All network requests are made to public, authoritative data sources (NOAA, NASA, USGS, Kyoto WDC). No authentication is required, which is appropriate for public data APIs. Code quality is solid with proper input validation, error handling, and no dangerous patterns detected. The non-commercial Kyoto Dst data is appropriately segregated and clearly labeled. Supply chain analysis found 3 known vulnerabilities in dependencies (1 critical, 1 high severity). Package verification found 1 issue.

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).

(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_dsttool description and theDstReadingschema (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.
