Create post
Publish a post, add it to the queue, schedule it or save a draft.
MCP tool tumblr_write → create_post
write Confirm
Creates a post on your blog under your name. Set state to published (default), queue, draft or private. With state queue and no publish_on, the post joins the end of the queue and follows the blog Queue settings. With publish_on it publishes at that time. Private posts cannot be queued. A full queue or the daily limit returns an error. By default you confirm each call; you can switch that off for this tool.
