README

solar-mcp

Part of the qso-graph project. No authentication required — all data from NOAA SWPC public endpoints.

Version drift? If the PyPI and MCP Registry badges show different versions, the Registry is catching up to the latest PyPI release on this server's next tag. Forward-only sync — we don't tag content-free releases just to sync. See qso-graph/.github TEMPLATES.md for the sync mechanism.

Install

pip install solar-mcp

Tools

Tool	Description
`solar_conditions`	Current SFI, Kp, and NOAA R/S/G space weather scales
