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 who work with amateur radio, fastmcp and propagation and want it reachable from 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

03 · What Solar MCP can do

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

What you can build

An agent gets 7 documented tools across solar, read & search, including solar_conditions, solar_forecast, solar_alerts, solar_wind.

06 · Solar MCP FAQ

Is Solar MCP still maintained?

Yes - as of 2026-09-18, its last commit was 2026-06-15. We re-verify nightly.

What can Solar MCP do?

An agent gets 7 documented tools across solar, read & search, including solar_conditions, solar_forecast, solar_alerts, solar_wind.

How do I install Solar MCP?

Run `uvx solar-mcp`. The README documents one environment variable (SOLAR_MCP_MOCK) to set first. You can also paste the ready-made client config above.

Does Solar MCP run locally?

Yes - it's a stdio server: it runs on your machine (via uvx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
