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.

Install

uvx solar-mcp            # run it; nothing to install

Ask questions

"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?"
