Schedule a post
Schedule a draft to publish at a future time, with an optional newsletter send.
MCP tool ghost_write → schedule_post
write Confirm
Returns the post with status scheduled and the time it will go out. At that time Ghost publishes the post and sends the email. A time in the past is rejected. Only a role that can publish may call it. By default you confirm each call; you can switch that off for this tool.
