Global volcanic eruptions from the Smithsonian Global Volcanism Program: VEI, location, dates.
Scored across 5 tools
Each tool targets a distinct step in the workflow: get_catalog lists packs, get_pack inspects one pack, get_data pulls rows, get_event drills into an event, and get_tool_help is meta. The list-vs-detail pair (get_catalog/get_pack) and the data-vs-event pair (get_data/get_event) have some conceptual overlap, but descriptions clearly explain the ordering and boundaries.
All five tools use a uniform get_noun snake_case pattern (get_catalog, get_data, get_event, get_pack, get_tool_help). There is no mixing of verb styles or casing conventions.
Five tools is reasonable and well-scoped for a read-only data-access facade, with each tool earning its place. It is slightly lean on discovery/search operations, but nothing is redundant.
The read path is well covered (catalog, pack metadata, data rows, event drill-down, help), but the get_catalog description explicitly directs users to get_geography for geometry, and no such tool exists in the set. This creates a dead end for geometry workflows referenced by other tools.
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.
Inputs: catalog (required). Returns: error, packs, detail, reason, +19 more
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.
Inputs: filters (required), metrics (required), pack_id (required), sort, +3 more. Returns: rows, sort, error, limit, +14 more
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.
Inputs: pack_id (required), event_id (required), source_id (required), limit, +4 more. Returns: error, event, reason, pack_id, +17 more
Inspect one exact data pack ID for its metrics, time coverage, and query metadata before get_data.
Inputs: pack_id (required). Returns: error, detail, reason, catalog, +12 more
Describe one tool visible on this facade, including its exact contract, or return a bounded workflow overview for one supported topic.
Inputs: topic, question, tool_name. Returns: ok, error, title, access, +13 more
