gbif_search_occurrences

io.github.cyanheads/gbif-biodiversity-mcp-server · Verify this server

Search 3.9B+ GBIF occurrence records with Darwin Core filters. Use taxonKey from gbif_match_species for reliable results — it resolves synonyms automatically. Accepts country (uppercase ISO 3166-1 alpha-2, where the record was observed), publishingCountry (the publishing organization's country — a different question), stateProvince, bounding box (decimalLatitude/decimalLongitude ranges), WKT polygon geometry, year range, month, basis of record, coordinate filter, and dataset key. Returns sightings only by default — GBIF also indexes absence records (surveys that looked and found nothing), and occurrenceStatus controls whether they are included. Pagination is capped at offset+limit=100,001 and GBIF offers no cursor or scroll, so a larger result set is covered only by partitioning it — facet it by DATASET_KEY with gbif_occurrence_facets and search each datasetKey separately. This server cannot download a result set in bulk; that needs the GBIF Download API with a GBIF.org account, or the GBIF snapshot on AWS Open Data.
