Wspr Mcp is an MCP server that provides WSPR beacon analytics for continuous automated propagation monitoring. It integrates with the wspr.live dataset (~2.7B spots, 2008–present) and is intended for amateur radio operators and propagation analysts.
Install via pip: pip install wspr-mcp. Invoke the server to expose tools for querying WSPR spot data, band activity, propagation paths, and SNR trends.
It uses the wspr.live database, containing approximately 2.7 billion spots from 2008 to the present.
Eight tools: wspr_spots, wspr_band_activity, wspr_top_beacons, wspr_top_spotters, wspr_propagation, wspr_grid_activity, wspr_longest_paths, wspr_snr_trend.
Install it via pip: `pip install wspr-mcp`.
Filters include callsign, band, grid square, SNR, and distance.
The README does not mention any authentication requirements; all data is sourced from the public wspr.live dataset.
