Get wspr-mcp service version and upstream spec version.

Returns the running PyPI version of wspr-mcp and the wspr.live ClickHouse schema revision in use. Use this to confirm fleet alignment across MCP deployments — agents can compare service_version and spec_version across servers to detect drift without going outside the MCP protocol.

Returns: service_name, service_version (PyPI), and spec_version (wspr.live schema).

Get recent WSPR spots.

WSPR beacons transmit every 2 minutes on precise frequencies. Each spot is a 2-minute integration proving a propagation path exists.

Get per-band WSPR activity summary.

Shows spot counts, TX/RX station counts, average and max distance, and average SNR for each band. The best indicator of which bands are open right now.

Get top WSPR transmitters ranked by spot count or max distance.

Shows the most active or most far-reaching WSPR beacon operators. Useful for finding who's putting out a big signal on a band.

Get top WSPR receivers ranked by spot count or max distance.

Shows the most prolific or most sensitive WSPR receiving stations. Useful for finding good receivers to monitor for propagation.

Get WSPR-derived propagation between two locations.

Shows which bands have been open between two endpoints, with spot counts, SNR statistics, and hours of opening. Accepts callsigns or grid squares (or a mix). Searches both directions automatically.

Get all WSPR activity in or out of a Maidenhead grid square.

Shows summary stats and recent spots for a geographic area. Use 2-character grid (e.g., DN) for a wide area or 4-character (e.g., DN13) for a specific region.

Get the longest WSPR paths in the given time window.

WSPR's precise timing and low power make it the gold standard for detecting marginal propagation. Long paths here prove the band is open.

Get SNR trend over time for a specific WSPR path.

Shows hourly SNR buckets for a path between two endpoints. Useful for seeing when a band opens and closes on a specific path, and how signal strength varies over time.
