What you can build

With this server connected, an agent can list all connected social accounts and their health status, get details for a specific account (token expiry, can-post status), get full details for a single post including all destinations (for drafts, the saved accounts + per-platform content), and publish now, schedule for later, or save as a draft for human review (draft: true).
