Postbase
Postbase is a social media scheduler with a calendar for X, LinkedIn, Bluesky, Mastodon, TikTok and YouTube. This connector lets Claude work with your Postbase workspace in plain language. What Claude can do: • List your connected social accounts • Write and schedule posts and threads, or save them as drafts • Show what's scheduled, drafted, published or failed • Cancel a scheduled post (it goes back to being a draft, so nothing is lost) Everything Claude creates lands on your Postbase calendar, where you can review, edit or cancel it before it goes out. Posts publish through each network's official API at the time you choose. Threads post as reply chains on X, Bluesky and Mastodon; on LinkedIn, extra parts become the first comment. Claude can't delete posts, disconnect accounts or change settings. You sign in with Postbase (no API key), pick which workspace Claude can access, and can revoke access at any time from Developers → Connected apps. Posts are text and threads today; add images and video in the Postbase composer.
