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

Count earthquakes matching a filter without returning the events — fast for questions like “how many M5+ quakes in the last 7 days near X”. Same filters as search_earthquakes (time, magnitude, circular area); for “last N days/hours” questions pass days/hours rather than computing start_time yourself. The response echoes the exact start_time/end_time and magnitude filter actually queried, ahead of the count itself. Keyless.

Parameters

Name	Type	Required	Description
`start_time`	string	no
`end_time`	string	no
`days`	number	no
`hours`	number	no
`min_magnitude`	number	no	Minimum magnitude (e.g. 5 for M5+).
`max_magnitude`	number	no	Maximum magnitude.
`latitude`	number	no	Center latitude for a circular search.
`longitude`	number	no	Center longitude for a circular search.
`max_radius_km`	number	no	Search radius in km around latitude/longitude.
