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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. Each band is rated " — ", the status one of five words defined in BAND-OUTLOOK.md: Excellent (wide open, strong long-lasting DX), Good (regular DX openings in the band's usual hours), Fair (short, patchy or weak openings; DX possible, not dependable), Poor (likely closed for DX, or degraded by absorption and noise), Sporadic (not graded from the indices: 6m opens by sporadic-E, and by F2 at high solar flux). The thresholds are rules of thumb on SFI and Kp, not a propagation model. |

Scored across 7 tools
Each tool maps to a distinct NOAA data source (conditions, forecast, alerts, wind, X-ray, band outlook), so selection is mostly clear. However, solar_conditions advertises an 'HF band outlook derived from current indices' while solar_band_outlook provides the band-by-band view, creating a real overlap that could cause misselection.
Six of seven tools follow a clean 'solar_<noun>' pattern (solar_conditions, solar_forecast, solar_wind, solar_xray, etc.) that reads predictably. get_version_info breaks the pattern with both a different prefix and a verb_noun form, but it's a single, clearly readable deviation.
Seven tools is well-scoped for a space-weather/HF-propagation server; each one covers a distinct data feed or derived assessment. No tool feels padded or redundant at the surface level.
The surface covers the full practical workflow: current indices, forecast, alerts, raw solar wind, flare class, and band-level propagation advice, plus a version tool. Minor gaps exist (e.g. sunspot number or historical/trend data), but agents can work around them via SFI and the 27-day forecast.
