• 2026-10-13uniprot_get_sequencechangeddescription, output schema
  before

  Fetch the canonical amino-acid sequence (FASTA) for a UniProtKB accession, with length and the parsed header. Set include_isoforms to also return the alternatively-spliced isoform sequences. This is the cheap sequence-only path — for the full functional record use uniprot_get_entry. Accessions come from uniprot_search_proteins or uniprot_map_ids; strip any "-N" isoform suffix (P04637-2 to P04637) before calling.

  Fetch the canonical amino-acid sequence (FASTA) for a UniProtKB accession, with length and the parsed header. Set include_isoforms to also return the alternatively-spliced isoform sequences. This is the cheap sequence-only path — for the full functional record use uniprot_get_entry. A merged accession returns the sequences of its merge target, labelled with the target accession and the requested one in mergedFrom; a demerged or deleted accession fails not_found naming its replacements or UniParc ID. Accessions come from uniprot_search_proteins or uniprot_map_ids; strip any "-N" isoform suffix (P04637-2 to P04637) before calling.

• 2026-10-13uniprot_get_taxonomychangeddescription, input schema, output schema
  before

  Resolve a taxonomy record by NCBI taxon ID (e.g. 9606) or scientific name (e.g. "Homo sapiens") — provide exactly one. Returns the scientific and common name, mnemonic, rank, parent, and the full lineage. Set include_children to also fetch immediate child taxa (a separate lookup — not inline on the record). Use this to turn an organism name into the taxon ID that uniprot_search_proteins (organism_id) and uniprot_get_proteome (taxon_id) expect.

  Resolve a taxonomy record by NCBI taxon ID (e.g. 9606) or scientific name (e.g. "Homo sapiens") — provide exactly one. Returns the scientific and common name, mnemonic, rank, parent, and the full lineage. Set include_children to also fetch immediate child taxa (a separate lookup — not inline on the record) in pages of 100 with the total child count; when more remain, pass the returned cursor to fetch the next page. Use this to turn an organism name into the taxon ID that uniprot_search_proteins (organism_id) and uniprot_get_proteome (taxon_id) expect.

  Translate identifiers across databases via UniProt's ID-mapping service — gene names to accessions, accession to PDB / Ensembl / RefSeq / ChEMBL / GeneID, and back. The job runs asynchronously; this tool submits it and polls within a budget. A running job returns status "running" with a ticket; pass that ticket alone to poll the same job. A completed call returns status "finished" with one results page; when continuation is present, pass it alone to fetch the next completed page without re-submitting or polling the job. A gene name often maps to one reviewed Swiss-Prot accession plus dozens of unreviewed TrEMBL ones, so target UniProtKB-Swiss-Prot (reviewed only) for the usual intent, or UniProtKB / UniProtKB_AC-ID to include TrEMBL. Pair a gene-symbol from_db with tax_id to disambiguate species. Chain the resulting accessions into uniprot_get_entry.

Chain the resulting active accessions into uniprot_get_entry.

• 2026-10-13uniprot_get_entrychangeddescription, input schema, output schema
  before

  Fetch full curated UniProtKB entries by accession in one batch (up to 20). Each entry carries function, catalytic activity, cofactors, subcellular location, disease involvement, PTMs, natural variants, isoforms, domains, GO terms, keywords, and cross-references. Partial failures do not abort the batch — resolved entries land in succeeded[] and unknown/withdrawn accessions in failed[]. Pass fields to trim the upstream projection. A single oversized record returns kind: "outline" (a section listing with byte sizes) instead of overflowing context — re-call the same accession with sections:[...] (e.g. ["disease","variants"]) to pull only those. This tool does not search: accessions come from uniprot_search_proteins.results[].accession or uniprot_map_ids. Strip any isoform suffix (P04637-2 to P04637) before calling.

  Fetch full curated UniProtKB entries by accession in one batch (up to 20). Each entry carries function, catalytic activity, cofactors, subcellular location, disease involvement, PTMs, natural variants, isoforms, domains, GO terms, keywords, and cross-references. Partial failures do not abort the batch — resolved entries land in succeeded[] and unknown or inactive (merged, demerged, deleted) accessions in failed[], where the error for an inactive accession names the accession to retry with or the UniParc ID that keeps its sequence. Pass fields to trim the upstream projection. A single oversized record returns kind: "outline" (a section listing with byte sizes) instead of overflowing context — re-call the same accession with sections:[...] (e.g. ["disease","variants"]) to pull only those. sections takes exactly one accession; trim a batch with fields instead. A list section too large on its own (the natural variants of p53, over a thousand) pages with section_limit/section_offset on a re-call naming that one section. This tool does not search: accessions come from uniprot_search_proteins.results[].accession or uniprot_map_ids. Strip any isoform suffix (P04637-2 to P04637) before calling.

  Search UniProtKB and return curated protein records. Pass text_search for a plain-language query (the 80% case) or query for the full Lucene field syntax (gene:TP53 AND organism_id:9606 AND reviewed:true) — exactly one is required. Reviewed (Swiss-Prot) entries are manually curated; unreviewed (TrEMBL) are computationally predicted and ~30x more numerous, so reviewed defaults to true to avoid drowning in predictions — set it false to include TrEMBL. Request facets (e.g. reviewed, model_organism) for server-side count breakdowns. Results page forward with an opaque cursor; UniProtKB has no offset paging. This is the discovery entry point — chain results[].accession into uniprot_get_entry for full records, or uniprot_get_sequence for FASTA.

Reviewed (Swiss-Prot) entries are manually curated; unreviewed (TrEMBL) are computationally predicted and ~30x more numerous, so reviewed defaults to true to avoid drowning in predictions — set it false to search both tiers together (for TrEMBL only, put reviewed:false in query). The organism_id and reviewed filters apply to the whole query. Request facets (e.g. reviewed, model_organism) for server-side count breakdowns. Results page forward with an opaque cursor; UniProtKB has no offset paging. An inactive accession the query matches (merged, demerged, or deleted) comes back in inactive[] with the accessions that replace it, never as a result. This is the discovery entry point — chain results[].accession into uniprot_get_entry for full records, or uniprot_get_sequence for FASTA.
