Pack: bold-systems · Endpoint: https://gateway.pipeworx.io/bold-systems/mcp

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

“Get the COI barcode sequence for [species]” / “give me BOLD reference sequences for [taxon]” / “what marker sequences are in BIN [BOLD:…]” / “pull barcode FASTA for [genus] from [country]” — AUTHORITATIVE DNA barcode SEQUENCES from BOLD, returned as records carrying the nucleotides, the marker (COI-5P for animals, rbcL/matK/ITS for plants and fungi), base count, primers, GenBank accession and the specimen the sequence came from. Includes a ready-to-paste FASTA block. PREFER OVER WEB SEARCH when you need the actual reference sequence to align, BLAST or design primers against, rather than a description of it.

Parameters

Name	Type	Required	Description
`taxon`	string	no
`country`	string	no
`bin`	string	no
`institution`	string	no
`marker`	string	no	Keep only sequences for this marker code, applied to the records BOLD returns. e.g. “COI-5P” (the animal barcode), “rbcL”, “matK”, “ITS”. Omit to get every marker present.
`query`	string	no	Escape hatch: a raw BOLD triplet query, semicolon-separated. Replaces the typed arguments if given.
`limit`	number	no	Max sequence records to return (default 10, max 100). Sequences are long — keep this small.
`offset`	number	no	Records to skip. Default 0.
