Trust breakdown (6 categories)

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
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

Tool Tokens
noaa_spaceweather_get_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.

NameTypeReqDescription
active_onlybooleanWhen true (default), return only in-force Warnings, Watches, and Alerts; exclude Summaries, Other, expired products, and cancellation notices. Set false to return all products, including cancellation…
max_age_hoursnumberMaximum 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."
NameTypeReqDescription
alertsarrayyesMatching SWPC alert/watch/warning records.
fetchedAtstringyesISO 8601 timestamp of when this data was fetched.
noticestringStatus notice when no alerts are active.
totalCountnumberyesCount of records in the alerts array.

No examples provided.

noaa_spaceweather_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.

NameTypeReqDescription
latitudenumberGeographic latitude in degrees (−90 to 90). Provide with longitude for a local aurora probability lookup.
longitudenumberGeographic longitude in degrees (−180 to 180). Provide with latitude for a local aurora probability lookup.
NameTypeReqDescription
forecastTimestringyesTime the aurora forecast is valid for, ISO 8601.
gridPointCountnumberyesTotal number of grid points in the OVATION model.
localLookupyesLocal aurora lookup result. Null when no coordinates were provided.
observationTimestringyesTime of the OVATION model observation, ISO 8601.
topAuroraPercentnumberyesHighest aurora probability anywhere on the globe (0–100).
topAuroraRegionstringyesApproximate region of the highest aurora probability grid point.

No examples provided.

noaa_spaceweather_get_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.

NameTypeReqDescription
auroraLatitudestringyesAurora visibility guidance for current conditions, e.g. "Aurora possible to ~55° geomagnetic latitude".
currentGScalenumberyesNOAA G-scale equivalent for current Kp (0–5).
currentKpnumberyesLatest observed planetary K-index (0–9).
forecastarrayyes3-day NOAA scale forecast (next 1–3 days).
observedAtstringyesUTC date and time of the NOAA scales data period this snapshot reflects, e.g. "2026-06-04 15:00:00".
summarystringyesPlain-language status summary suitable for display, e.g. "Quiet conditions" or "G2 moderate geomagnetic storm in progress."
todayobjectyesCurrent observed NOAA storm scales for today.

No examples provided.

noaa_spaceweather_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.

NameTypeReqDescription
window_daysintegerNumber of past days of observed Kp to return (1–7, default 1). Larger windows show trend context.
NameTypeReqDescription
auroraLatitudestringyesAurora visibility guidance for current conditions.
currentGScalenumberyesNOAA G-scale for current Kp.
currentKpnumberyesLatest observed Kp value.
forecastarrayyesForward-looking Kp forecast series (estimated and predicted entries only; observed history excluded).
observedarrayyesObserved Kp readings within the requested window, oldest first.
observedCountnumberyesNumber of Kp observations in the observed array, matching the requested window.

No examples provided.

noaa_spaceweather_get_solar_activity ~141

Solar flare and radiation storm picture: recent GOES X-ray flux with flare-class labels (A/B/C/M/X), 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). Active region data helps identify which region is driving current activity.

NameTypeReqDescription
include_regionsbooleanInclude active solar region details (default true). Set false to skip region data and reduce response size.
NameTypeReqDescription
activeRegionsarrayyesCurrently active solar regions with per-region flare probabilities. Empty when include_regions=false or no regions are active.

latestProtonyesMost recent ≥10 MeV proton flux reading, null if unavailable.
latestXrayyesMost recent GOES X-ray flux reading, null if unavailable.
probabilitiesarrayyes3-day flare probability forecasts.
recentXrayarrayyesGOES X-ray flux readings from the past hour, oldest first.
sScalenumberyesCurrent NOAA S-scale for solar radiation storms (0–5), derived from latest proton flux.
sScaleTextstringyesPlain-language S-scale description, e.g. "S2 moderate radiation storm".

No examples provided.

noaa_spaceweather_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.

NameTypeReqDescription
window_hoursintegerHours 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…
