Create a post
Schedule a post, add it to a queue or save it as a draft, for one or more profiles.
MCP tool sendible_write → create_post
write Confirm
mode schedule publishes at send_at in the workspace time zone, queue adds the post to the queue's next free slot, and draft saves it in Publish > Drafts without a time. The post takes text, one link and one image URL; nothing is uploaded. Sendible limits published posts per day per workspace: 20 on a trial, 100 on Core, 200 on Plus, 300 on Premium, 500 on Elite and Enterprise. A draft reaches no one, but the same tool schedules real posts, so every call asks. By default you confirm each call; you can switch that off for this tool.
