Solar MCP

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. Its 7 documented tools cluster into solar, read & search. It runs locally over stdio via the published package.

People connecting maps & location tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Solar MCP

before you install - you'll need

SOLAR_MCP_MOCK

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add qso-graph-solar-mcp -- uvx solar-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "qso-graph-solar-mcp": {
      "command": "uvx",
      "args": [
        "solar-mcp"
      ]
    }
  }
}

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

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license no standard license detected - usage rights unclear; check the repo before commercial use

pypi package solar-mcp - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.qso-graph is GitHub-verified and matches the repo owner
