Server Configuration
Describes the environment variables required to run the server.
| Name | Required | Description | Default |
|---|---|---|---|
| SOLAR_MCP_MOCK | No | Set to 1 to mock data for testing without network. | 0 |
Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| get_version_infoA | 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). |
| solar_conditionsA | 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. |
| solar_forecastA | 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. |
| solar_alertsA | 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. |
| solar_windA | 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. |
| solar_xrayA | 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. |
| solar_band_outlookA | 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. |

Scored across 7 tools
Each tool covers a distinct aspect of solar and space weather data—alerts, current conditions, forecasts, wind, X-ray flux, propagation outlook, and version info. There is minor overlap between solar_band_outlook and solar_conditions (both include HF outlook), but descriptions and primary outputs clearly differentiate them.
Six of seven tools follow a consistent 'solar_<noun>' pattern (solar_alerts, solar_conditions, etc.). The outlier is 'get_version_info', which uses a verb_noun style and breaks the prefix convention. This small inconsistency prevents a perfect score.
With 7 tools covering alerts, current conditions, forecasts, wind, X-ray flux, and propagation outlook, the set is well-scoped for the domain. No tool feels extraneous, and the count is typical for a focused data-providing MCP server.
The tool surface covers the core needs of an agent interested in HF propagation: current indices, alerts, forecast, solar wind, and X-ray data. Minor gaps exist, such as the lack of sunspot number or solar imagery, but these are not essential for the server's stated purpose.
