Choose data or geometry to list published pack IDs or family and scope IDs. The response includes a complete catalog download URL. Use get_pack for data or get_geography for geometry. Current catalog: The same geography tools work worldwide across a cataloged baseline of 252 geographic entities, reaching up to Admin 2. Where additional country releases are available, the same calls automatically return deeper administrative tiers or maintained reference families. Additional detail is currently available for Australia, Brazil, Canada, France, Germany, Mexico, United Kingdom, United States.
Required directory selector.

}Retrieve rows from one selected published data pack using exact metrics, loc_id-based region filters, time/metric filters, sorting, and a row limit. Disaster event rows include stable event_id values for get_event drill-down. A parent administrative loc_id selects matching descendant rows at the pack's published grain. Call get_pack first; geometry families use their focused next-step tools.
| Argument | Type | Description |
|---|---|---|
| sort | any | Sort by a sortable field from get_pack; direction defaults to asc. |
| limit | integer | Maximum number of rows to return for the requested source or pack. |
| output | object | Optional response controls. v1 supports rows only. |
| filters* | object | |
| metrics* | array | Exact metric ids from get_pack. Use event_count for aggregate counts only when get_pack publishes it. |
| pack_id* | string | Pack identifier from get_catalog. Newly catalog-admitted packs require no MCP schema change. |
| request_id | string | Optional caller-supplied request id for tracing and idempotency. |

}Retrieve one exact disaster event and explicitly requested relationships, affected places, native observations, or geometry. Use get_data to obtain the stable event_id first.
| Argument | Type | Description |
|---|---|---|
| limit | integer | Per-section ceiling for relationships, affected places, observations, or geometry frames. |
| include | array | Optional companion layers. Omit for the lightweight event summary. Geometry is never returned implicitly. |
| pack_id* | string | Required disaster pack_id that returned this event_id from get_data. The tool never searches other packs. |
| event_id* | string | Exact stable event_id returned by a disaster-pack get_data row. |
| source_id* | string | Required source_id from the same get_data result. Must identify one published event source in pack_id. |
| request_id | string | Optional caller-supplied request id for tracing. |
| geometry_mode | string | current returns the representative/current shape; timeline returns bounded progression frames where supported. |
Inspect one exact data pack ID for its metrics, time coverage, and query metadata before get_data.
| Argument | Type | Description |
|---|---|---|
| pack_id* | string | Pack identifier from get_catalog. Newly catalog-admitted packs require no MCP schema change. |
