Is noaa-spaceweather-mcp-server live?

Yes — it answered the hub's last check (checked 10m ago). It answered 99% of checks over the last 30 days.

Is noaa-spaceweather-mcp-server free to use?

Yes — the hub reached it with no key and no payment.

What tools does noaa-spaceweather-mcp-server have?

6 tools: noaa_spaceweather_get_aurora_forecast, noaa_spaceweather_get_kp_index, noaa_spaceweather_get_solar_activity, noaa_spaceweather_get_alerts, noaa_spaceweather_get_solar_wind, noaa_spaceweather_get_conditions.

Is noaa-spaceweather-mcp-server safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• noaa_spaceweather_get_aurora_forecast reads open 12h ago

  OVATION model aurora forecast for the next ~30–60 min: global grid of aurora probability percentages by latitude/longitude (1° resolution). With optional coordinates, returns the local aurora probability at the nearest grid point, the geomagnetic latitude those coordinates convert to, the minimum Kp and G level needed for aurora at that geomagnetic latitude, the sun’s elevation there at the forecast time (aurora is not visible in daylight), the strongest aurora within 1000 km poleward (visible low on the horizon when bright), and a plain-language go/no-go verdict. Without coordinates, returns only global metadata. Data updates every ~5 minutes. Supply coordinates as geographic (WGS84); aurora bands are geomagnetic, and the tool converts between them.

• noaa_spaceweather_get_kp_index reads open 21h ago

  Planetary K-index (0–9 geomagnetic activity scale) — recent observed 3-hour values with their NOAA G-scale equivalents and aurora-latitude guidance, plus the 3-day Kp forecast series. Kp is the primary driver of aurora visibility and geomagnetic storm severity. SWPC reports Kp in thirds and starts each G level at that level’s "minus" value: Kp 4.67 (5−) is G1, Kp 6.67 (7−) is G3 (aurora to ~50° geomagnetic), Kp 8.67 (9−) is still G4, and only Kp 9 is G5 extreme. Use noaa_spaceweather_get_conditions for a combined snapshot including storm scales; use this tool when you need the Kp time series or forecast detail.

• noaa_spaceweather_get_solar_activity reads open 21h ago

  Solar flare and radiation storm picture: discrete flare events from the past week with peak class and R-scale level, recent GOES X-ray flux with flare-class labels (A/B/C/M/X) and class magnitude, the daily F10.7 cm solar radio flux, 3-day flare-class probabilities (C/M/X), active solar regions with per-region flare probabilities, and GOES integral proton flux at ≥10 MeV with NOAA S-scale. For operators tracking HF radio blackout (R-scale, driven by X-ray) and radiation storm risk (S-scale, driven by protons). Each active region carries the C/M/X flare counts SWPC attributed to it that UTC day, which identify the region driving current activity — the flare events themselves carry no region.

• noaa_spaceweather_get_alerts reads open 12h ago

  Active SWPC alerts, watches, and warnings — parsed into structured records with product type, NOAA scale and level, issue time, serial number, validity window, and plain text. Covers geomagnetic storms, radio blackouts, and radiation storms. With active_only=false, also returns informational summaries, expired notices, and cancellations. max_age_hours controls how far back to look for candidates (default 48 h) — under active_only=true it does not cut off a product whose validity end is still in the future, and under active_only=false it is a literal age cutoff. The SWPC feed keeps all historical records and has no built-in expiry.

• noaa_spaceweather_get_solar_wind reads open 21h ago

  Real-time solar wind measurements from the active spacecraft at L1: proton speed (km/s), density (n/cm³), temperature (K), and the critical Bz component (southward Bz = negative = storm driver). Returns the recent plasma and magnetic field time series within the requested window, oldest first, each record tagged with the reporting spacecraft and bounded to 200 records per series unless resolution is set to "full" — or omitted entirely under "summary", which keeps the latest readings, Bz status, and window extremes (peak speed, density, and Bt; most southward Bz; minutes of southward Bz) for "what is Bz doing now" questions. Bz < −10 nT for sustained periods is a primary geomagnetic storm trigger — use alongside noaa_spaceweather_get_kp_index to see whether elevated solar wind has translated into a geomagnetic storm.

• noaa_spaceweather_get_conditions reads open 12h ago

  Current space-weather snapshot: NOAA R/S/G storm scales (the previous UTC day, today, and the 3-day forecast), latest Kp index with its G-scale equivalent and aurora-visibility latitude, and a plain-language status summary. Optionally includes the SWPC forecast discussion explaining what is driving the forecast. The quickest way to answer "is anything happening right now?" — use before deciding whether to drill into solar wind (noaa_spaceweather_get_solar_wind), aurora (noaa_spaceweather_get_aurora_forecast), or alert details (noaa_spaceweather_get_alerts).
