Get solar-mcp service version and upstream spec version.

Returns the running PyPI version of solar-mcp and the NOAA SWPC endpoint set revision currently in use. Use this to confirm fleet alignment across MCP deployments — agents can compare service_version and spec_version across servers to detect drift without going outside the MCP protocol.

Returns: service_name, service_version (PyPI), and spec_version (NOAA SWPC endpoint set).

Get current solar conditions — SFI, Kp, and NOAA space weather scales.

Returns the latest 10.7 cm solar flux index (SFI), planetary Kp index, and NOAA R/S/G scales (radio blackout, solar radiation, geomagnetic storm). Includes an HF band outlook derived from current indices.

Returns: Current SFI, Kp, NOAA scales, and band-by-band propagation outlook.

Get the NOAA 27-day solar flux and geomagnetic forecast.

Shows predicted SFI and Kp values for the next 27 days, useful for planning DX operations, contests, and POTA/SOTA activations.

Returns: Day-by-day forecast with predicted SFI and Kp values.

Get active NOAA space weather alerts and warnings.

Shows current solar flare alerts, geomagnetic storm warnings, radiation storm alerts, and other SWPC bulletins.

Returns: List of active alerts with product ID, issue time, and message text.

Get real-time DSCOVR L1 solar wind data.

Shows interplanetary magnetic field (Bz component), solar wind speed, and proton density from the DSCOVR satellite at L1 (~1.5M km sunward). Southward Bz (negative) drives geomagnetic storms.

Returns: Bz (nT), Bt (nT), wind speed (km/s), density (p/cm³), and geomagnetic storm assessment.

Get GOES X-ray flux and solar flare status.

Shows the current X-ray classification (A, B, C, M, X) from GOES satellite data. M and X class flares can cause HF radio blackouts.

Returns: Current flare class, X-ray flux, and HF impact assessment.

Get HF band-by-band propagation outlook based on current conditions.

Derives a propagation assessment for each HF band (160m through 6m) from the current SFI and Kp values. Useful for deciding which band to operate on right now.

Returns: Per-band condition rating (Poor/Fair/Good/Excellent) with explanation, plus current SFI and Kp values.
