ListNaturalEvents
ListNaturalEvents retrieves seeded EONET/GDACS/NHC/HKO natural events. Empty events with fetched_at=0 or data_available=false means the seed snapshot is unavailable/degraded, not that there are confirmed zero events.
Query Parameters
Accepted but currently ignored; no-op until this handler supports the parameter.
Optional JMESPath expression applied server-side to project or reduce the JSON response before it is returned (mirrors the MCP jmespath argument). Invalid expressions, expressions larger than 1024 UTF-8 bytes, or projections that exceed the 256 KB output cap return HTTP 400 with a {_jmespath_error, original_keys} envelope. Grammar and worked examples: https://www.worldmonitor.app/docs/mcp-jmespath.
Response
Successful response
Time the seed snapshot was fetched, as Unix epoch milliseconds. A value of 0 means the snapshot is unavailable/degraded, not that there are confirmed zero natural events.. Warning: Values > 2^53 may lose precision in JavaScript
True when events came from a seed snapshot. False means an empty payload is graceful degradation because the snapshot is unavailable.
