Update domain

MCPupdate_domainWRITE$0.02 / call

Set or remove a custom domain (e.g. docs.yourcompany.com). REQUIRES BUSINESS plan.

Arguments

workspace_idstringrequired

Numeric workspace id — OR the project as the user names it: 'owner/repo', the repo name alone, the site's display name, its docs URL or custom domain. Text is resolved server-side; an ambiguous name returns the candidates instead of guessing, so pass what the user said rather than calling list_workspaces first.

custom_domainstringrequired

Custom domain name, or empty string to remove
