Noaa Spaceweather MCP Server

@cyanheads/noaa-spaceweather-mcp-server Query NOAA SWPC space weather: geomagnetic storm scales, Kp index, aurora forecasts, solar wind, solar activity, and alerts via MCP. STDIO or Streamable HTTP. Its 6 documented tools cover noaa, spaceweather, solar.

People who work with noaa, spaceweather and solar and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Noaa Spaceweather MCP Server

before you install - you'll need

Set MCP_TRANSPORT_TYPE, MCP_LOG_LEVEL before connecting.

Claude Code

claude mcp add cyanheads-noaa-spaceweather-mcp-server --transport http https://noaa-spaceweather.caseyjhand.com/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "cyanheads-noaa-spaceweather-mcp-server": {
      "url": "https://noaa-spaceweather.caseyjhand.com/mcp"
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

03 · What Noaa Spaceweather MCP Server can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

An agent gets 6 documented tools spanning noaa, spaceweather, solar, including noaa_spaceweather_get_conditions, noaa_spaceweather_get_kp_index, noaa_spaceweather_get_aurora_forecast, noaa_spaceweather_get_solar_wind.

The 6 tools it gives your agent

Extracted from the project's README - what noaa-spaceweather-mcp-server lets an agent do.

noaa_spaceweather_get_conditions: - Current space-weather snapshot: NOAA R/S/G storm scales, latest Kp, a plain-language status summary, and optionally SWPC's forecast discussion explaining the fo
noaa_spaceweather_get_kp_index: - Planetary K-index (0–9) - recent observed 3-hour values with G-scale equivalents and aurora-latitude guidance, plus 3-day forecast
noaa_spaceweather_get_aurora_forecast: - OVATION model aurora forecast: global probability grid, optional local lookup by coordinates with go/no-go verdict
noaa_spaceweather_get_solar_wind: - Real-time solar wind from the active L1 spacecraft: speed, proton density, temperature, and the critical Bz component with the window's most southward reading -
noaa_spaceweather_get_solar_activity: - Solar flare picture: discrete flare events with peak class and R-scale level, GOES X-ray flux, the daily F10.7 cm radio flux, 3-day flare-class probabilities, a
noaa_spaceweather_get_alerts: - Active SWPC alerts, watches, and warnings - structured records with product type, severity, issue time, validity window, and full message text
