No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/donki_geomagnetic_storms for the schema, then POST the same URL with its arguments for the data.

“Was there a geomagnetic storm?” / “will there be an aurora tonight?” / “how strong was the Kp index?” — geomagnetic storm events from NASA DONKI, each with the full series of observed Kp index readings and their timestamps. AUTHORITATIVE for whether Earth’s magnetic field was actually disturbed, as opposed to whether a flare happened: Kp 5 is a minor storm, Kp 7 puts aurora over the northern US and northern Europe, Kp 8-9 is severe. Also returns the CMEs and shocks DONKI linked to each storm, so you can trace a storm back to the eruption that caused it.

Parameters

Name	Type	Required	Description
`start_date`	string	no	Start date YYYY-MM-DD (optional; DONKI defaults to ~30 days ago).
`end_date`	string	no	End date YYYY-MM-DD (optional; defaults to today).
`min_kp`	number	no	Only return storms whose peak observed Kp reached at least this value (5 = minor storm, 7 = strong, 9 = extreme).
`limit`	number	no	Max storms to return (default 50, max 200).
`_apiKey`	string	no	NASA API key (optional, defaults to DEMO_KEY)
