Paleobiology Database MCP tools

The 8 tools the Paleobiology Database server offers to Kahubi. The assistant picks the right one for each question.

• paleobiology_search_occurrences

  Search fossil occurrences by clade-inclusive base_name or base_id, exact taxon_name, interval or max_ma/min_ma, modern geographic bounds, country, formation, environment, or col...

• paleobiology_get_taxon

  Resolve a taxon by name (e.g.

• paleobiology_get_diversity

  Compute a diversity / origination / extinction curve for a clade across geologic time, binned by period, epoch, or age - answers "plot dinosaur genus diversity across the Mesozo...

• paleobiology_list_intervals

  Look up the geologic time scale - eons, eras, periods, epochs, and ages with their absolute-age boundaries in millions of years (Ma) and nesting.

• paleobiology_search_collections

  Find fossil collections (localities) by area and geologic time - "what has been dug up here, and from what rock." Each locality returns its location, age (named interval and Ma)...

• paleobiology_get_references

  Resolve PBDB reference_no values - the source publication on every paleobiology_search_occurrences and paleobiology_search_collections row - to full citations with authors, year...

• paleobiology_dataframe_query

  Run a read-only SQL SELECT against occurrence result sets staged on a DataCanvas by paleobiology_search_occurrences.

• paleobiology_dataframe_describe

  List the tables and their columns staged on a DataCanvas by paleobiology_search_occurrences.

Using Paleobiology Database in Kahubi

• Community server. An open-source server maintained by the MCP community. Kahubi tests it with live queries before listing it and health-checks it regularly.
• Cited, checkable answers. Results are treated as retrieved material and cited with the source’s own identifiers, so you can open every record the answer relied on.
• Your files stay private. Only the search the assistant writes for your question is sent to Paleobiology Database.
