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

Solar energetic particle (SEP) events from NASA DONKI — bursts of high-energy protons arriving at Earth after a flare or CME. These are the events behind radiation warnings for polar airline routes, astronaut EVA holds and satellite single-event upsets. Returns the event time, the detecting instruments and energy channels (e.g. “GOES-P: SEISS >10 MeV”), and the flare or CME DONKI linked as the source.

Parameters

Name	Type	Required	Description
`start_date`	string	no	Start date YYYY-MM-DD (optional; DONKI defaults to ~30 days ago). SEP events are rare — a year-wide window is often the right query.
`end_date`	string	no	End date YYYY-MM-DD (optional; defaults to today).
`limit`	number	no	Max events to return (default 50, max 200).
`_apiKey`	string	no	NASA API key (optional, defaults to DEMO_KEY)
