For AI assistants · MCP

Space weather, served straight to your AI

solarstorm.today runs a free public MCP server — the same live NOAA data that powers this site, exposed as tools any MCP-capable assistant can call: Claude, Claude Code and other MCP clients.

Endpoint · https://mcp.solarstorm.today/mcp

What your assistant gets

ToolReturns
get_current_kpCurrent planetary Kp index, activity level and the observed 24-hour maximum.
get_kp_forecast_3dayThe official NOAA forecast: maximum expected Kp for each of the next three days.
get_solar_flares_24hCurrent GOES X-ray class and the strongest flare of the past 24 hours (e.g. M6.9).
get_aurora_visibilityFor any latitude: the Kp you need, tonight's expected maximum, and a plain-language verdict.

Connect in one minute

Claude (web/desktop): Settings → Connectors → Add custom connector → paste https://mcp.solarstorm.today/mcp. Then ask: "Will I see aurora in Vienna tonight?"

Claude Code:

claude mcp add --transport http solarstorm https://mcp.solarstorm.today/mcp

No API key, no signup. The server is stateless and fetches fresh NOAA data on every call, so answers match the live dashboard and the aurora page.

Fair use

Free for personal and research use. The upstream data is public NOAA/SWPC; please don't hammer the endpoint with automated bulk polling — for that, use NOAA's feeds directly. Questions or ideas: hello@solarstorm.today.
