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.
What your assistant gets
| Tool | Returns |
|---|---|
| get_current_kp | Current planetary Kp index, activity level and the observed 24-hour maximum. |
| get_kp_forecast_3day | The official NOAA forecast: maximum expected Kp for each of the next three days. |
| get_solar_flares_24h | Current GOES X-ray class and the strongest flare of the past 24 hours (e.g. M6.9). |
| get_aurora_visibility | For 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.
