`resolve_xref`

Pack: hgnc · Connect: https://pipeworx.io/mcp (see Connect below for a single-pack URL)

No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/resolve_xref for the schema, then POST the same URL with its arguments for the data.

Reverse-lookup: map an external database id to its canonical HGNC gene. “What gene is Entrez 672?” -> BRCA1. Accepts entrez_id, ensembl_gene_id, uniprot_ids, omim_id, refseq_accession, or ucsc_id and returns the same full record as get_gene. Keyless.

Parameters

Name	Type	Required	Description
`id_type`	string	yes	External id namespace: one of entrez_id, ensembl_gene_id, uniprot_ids, omim_id, refseq_accession, ucsc_id.
`id`	string	yes	The external id, e.g. entrez “672”, ensembl “ENSG00000012048”, uniprot “P38398”, omim “113705”.
