About NCBI E-utilities
Entrez search and document summaries across NCBI databases. Ask for a gene’s ClinVar variants, a taxon’s lineage, a protein accession or a PubMed Central id set, then summarise the hits.
Questions you can ask NCBI E-utilities
Type them into Kahubi’s chat once NCBI E-utilities is connected.
“How many pathogenic BRCA2 variants are listed in ClinVar?”
What comes back: The total count from an Entrez search, plus summaries of the top hits with clinical significance.
“Give me the full taxonomic lineage of Borrelia burgdorferi.”
What comes back: The NCBI Taxonomy record with lineage, rank and taxon id.
NCBI E-utilities MCP tools
The 2 tools the NCBI E-utilities server offers to Kahubi. The assistant picks the right one for each question.

ncbi_summaryDocument summaries for up to 50 ids in one database (title/description, organism, location, clinical significance …).
Using NCBI E-utilities in Kahubi
- Hosted by Kahubi. Kahubi runs this server itself so it stays reliable enough for research use.
- 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 NCBI E-utilities.
