How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →
Endpoint Security66
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 6 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability69
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 1127 tokens (~187/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
- Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

noaa_spaceweather_get_alerts Get Space Weather Alerts ~202
Active SWPC alerts, watches, and warnings — parsed into structured records with product type, NOAA scale and level, issue time, 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 (default 48 h); the SWPC feed keeps all historical records and has no built-in expiry.

| max_age_hours | number | — | Maximum age of alerts to return, in hours (default 48). The SWPC feed retains all historical records — this window prevents returning weeks of historical notices as "active." |
| Name | Type | Req | Description |
|---|---|---|---|
| alerts | array | yes | Matching SWPC alert/watch/warning records. |
| fetchedAt | string | yes | ISO 8601 timestamp of when this data was fetched. |

noaa_spaceweather_get_aurora_forecast Get Aurora Forecast ~167
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 minimum Kp needed for aurora at that latitude, and a plain-language go/no-go verdict. Without coordinates, returns only global metadata. Data updates every ~5 minutes. Coordinates are geographic (WGS84), not geomagnetic.

No examples provided.
noaa_spaceweather_get_conditions Get Space Weather Conditions ~113
Current space-weather snapshot: NOAA R/S/G storm scales (today + 3-day forecast), latest Kp index with its G-scale equivalent and aurora-visibility latitude, and a plain-language status summary. 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).
Input schema present but exposes no named parameters.
| Name | Type | Req | Description |
|---|---|---|---|
| auroraLatitude | string | yes | Aurora visibility guidance for current conditions, e.g. "Aurora possible to ~55° geomagnetic latitude". |

noaa_spaceweather_get_kp_index Get Kp Index ~168
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: Kp≥5 is G1, Kp≥7 is G3 (aurora to ~50°), 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.
| Name | Type | Req | Description |
|---|---|---|---|
| window_days | integer | — | Number of past days of observed Kp to return (1–7, default 1). Larger windows show trend context. |
| Name | Type | Req | Description |
|---|---|---|---|
| auroraLatitude | string | yes | Aurora visibility guidance for current conditions. |
| currentGScale | number | yes | NOAA G-scale for current Kp. |
| currentKp | number | yes | Latest observed Kp value. |
| forecast | array | yes | Forward-looking Kp forecast series (estimated and predicted entries only; observed history excluded). |
| observed | array | yes | Observed Kp readings within the requested window, oldest first. |
| observedCount | number | yes | Number of Kp observations in the observed array, matching the requested window. |
No examples provided.

noaa_spaceweather_get_solar_wind Get Solar Wind ~214
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. 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.

|---|---|---|---|
| window_hours | integer | — | Hours of recent solar wind history to return (1–168, default 3). Records update ~every 1 min, but the feed only carries roughly the last 24 hours — a larger window returns the whole feed, not more hi… |
| Name | Type | Req | Description |
|---|---|---|---|
