z2h_confirm_source_uploadAfter the signed PUT succeeds, verify and attach the archive to the owned draft.No findings
Why it is in this group
- The name "z2h_confirm_source_upload" says "upload": a word for a change.
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
After the signed PUT succeeds, verify and attach the archive to the owned draft. Confirm that the Builder accepted "I own or have the rights to sell the codebase I am about to upload."; pass ownershipAccepted=true and ownershipVersion=2026-09-27. The server records the accepted wording with the source change. Final review and publishing stay in the web wizard.

4 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
