`clearlydefined_definition`

Pack: clearlydefined · Endpoint: https://gateway.pipeworx.io/clearlydefined/mcp

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

Get the curated licence and attribution record for one exact component version from ClearlyDefined: declared SPDX licence, every licence expression discovered in the files, the copyright holders that must be attributed, the upstream source repo + commit the release was built from, release date, file hashes, and 0-100 completeness scores. AUTHORITATIVE for “what licence is @ really under” and “who do I have to attribute” — it reports what scanners found in the shipped files, not just what the manifest claims. Keyless.

Parameters

Name	Type	Required	Description
`include_files`	boolean	no	Include the per-file licence/attribution rows (can be long). Default false.
`file_limit`	number	no	How many file rows to include when include_files is true. Default 50, max 500.
