`ucsc_tracks`

Pack: ucsc-genome · Endpoint: https://gateway.pipeworx.io/ucsc-genome/mcp

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

“What annotation tracks does UCSC have for hg38” / “does [assembly] have a [ClinVar/GENCODE/conservation/repeat] track” / “what is the track name for [dataset] in the genome browser” — lists the annotation tracks available on one UCSC assembly, with each track’s internal name, short and long label, data type and parent container. AUTHORITATIVE for the track argument of ucsc_track_data: the browser shows human-readable labels, the API wants the internal name (e.g. label “GENCODE V50” is track knownGene), and there is no way to guess one from the other.

Parameters

Name	Type	Required	Description
`genome`	string	yes
`search`	string	no	Case-insensitive substring filter over track name, short label and long label. e.g. “clinvar”, “gencode”, “conservation”.
`limit`	number	no	Max tracks to return (default 100, max 1000).
