Download an artifact

GET/repos/{owner}/{name}/actions/artifacts/{id}/zip

Over REST, GET …/zip answers 302 with the link in Location, as GitHub does: curl -L follows it. Over MCP the link is returned as url, with expires_at. Needs the Read role.

Over REST the answer is 302 Found with the link in Location, as GitHub’s is, so curl -L -o web-dist.zip …/zip saves the file; the body above is what the MCP workflow tool’s download_artifact returns. The link needs no token and stops working after 10 minutes.

• Authentication: Optional. Public data can be read without a token; send one to see what is private.
• MCP tool: workflow with action download_artifact, and the same inputs
• Scope: An access token needs workflows:read.
