1Social

1Social publishes to Instagram, TikTok, LinkedIn, X (Twitter), Facebook, Threads and Bluesky from a single message — right away, or scheduled up to 30 days ahead. Before anything goes out, Claude can check the draft: per-network character counts, whether a network requires an image (Instagram and TikTok refuse posts without one), whether a multi-part post will publish as a native thread or be joined into a single post, and what it would cost against your remaining quota. The check publishes nothing and spends no quota. After publishing, Claude reports each network separately — what landed, with a link to the live post; what failed, with a readable reason; and the rare case where 1Social genuinely cannot tell. A network that failed can be retried on its own, without re-posting to the ones that already went out. Anything still scheduled can be edited or unscheduled, and deleted from the networks whose APIs allow deletion. Attach an image or video straight from the conversation, or pass a public URL. Ten tools: list_accounts, preview_post, publish_post, list_posts, update_post, cancel_post, delete_post, retry_delivery, upload_media, confirm_delivery. Connecting your social accounts happens in your browser at 1social.dev, through each network's own OAuth flow. There are no API keys to paste, and the agent never sees the credentials for your social accounts. Every account gets 30 deliveries a month free — pricing is per delivery, so one post to seven networks is seven deliveries. Paid plans are Solo $19/mo and Pro $39/mo.
