Solar indices and space weather MCP server. SFI, SSN, Kp, DSCOVR, NOAA alerts.
Local MCP server that gives an assistant live NOAA space weather data — solar flux, Kp, solar wind, X-ray flares, alerts, 27-day forecast and HF band outlook.
Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.
Follow the launch instructions in the repository.
MCP server for space weather and HF propagation conditions — live solar flux, Kp index, DSCOVR solar wind, X-ray flux, alerts, 27-day forecast, and band-by-band outlook through any MCP-compatible AI assistant.
Part of the qso-graph project. No authentication required — all data from NOAA SWPC public endpoints.
No credentials needed — just install and configure your MCP client.
Add to claude_desktop_config.json (~/Library/Application Support/Claude/ on macOS, %APPDATA%\Claude\ on Windows):
Add to .claude/settings.json:

Add to ~/.gemini/settings.json (global) or .gemini/settings.json (project):
"What are the current solar conditions?"
"Is the solar wind causing any geomagnetic disturbance?"
"What's the 27-day solar forecast look like?"
"Are any bands open right now on HF?"
"Are there any active space weather alerts?"
"What class solar flare is happening?"
Every value comes from a public NOAA Space Weather Prediction Center endpoint at services.swpc.noaa.gov:

Get Version Info
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.
Takes no parameters.
Solar Conditions
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.
Takes no parameters.
Solar Forecast
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.
Takes no parameters.
Solar Alerts
Get active NOAA space weather alerts and warnings. Shows current solar flare alerts, geomagnetic storm warnings, radiation storm alerts, and other SWPC bulletins.
Takes no parameters.
Solar Wind
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.
Takes no parameters.
Solar Xray
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.
Takes no parameters.
Solar Band Outlook
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 "<status> — <comment>", 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.
Takes no parameters.
90% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
