Connect Solarstorm and your agent gets 4 tools, among them get_aurora_visibility, get_current_kp, get_kp_forecast_3day. It answers at https://mcp.solarstorm.today/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 6 of 6 times since 12 September 2026; the last check, on 24 October 2026, succeeded.
Space weather: Kp index, NOAA 3-day geomagnetic forecast, solar flares, aurora visibility.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
get_aurora_visibility | Aurora visibility outlook for a geographic latitude (degrees, e.g. 48.2 for Vienna): the Kp you need there, the expected maximum Kp in the next 24 h, and a verdict. Inputs: latitude |
get_current_kp | Current planetary Kp index: latest value, level (low/moderate/high/severe) and the observed 24-hour maximum. |
get_kp_forecast_3day | Official NOAA 3-day geomagnetic forecast: the maximum expected Kp per calendar day (Europe/Berlin days). |
get_solar_flares_24h | Solar X-ray activity of the past 24 hours from GOES: current flare class and the 24-hour peak class. |

It answered our last check on 24 October 2026 in 88 ms. Over 6 checks since 12 September 2026 it answered 6. Status here comes from Neuronto's own probes, not from the publisher.
Yes. It is published by solarstorm.today and served from mcp.solarstorm.today, the vendor's own domain: https://mcp.solarstorm.today/mcp.
4, as returned by the server's own tools/list on 23 September 2026: get_aurora_visibility, get_current_kp, get_kp_forecast_3day, get_solar_flares_24h.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.solarstorm.today/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
Publisher: today.solarstorm. Endpoint host: mcp.solarstorm.today. ARD identifier: urn:air:today.solarstorm:mcp:solarstorm.
First indexed 10 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
