What can the Socialync MCP server do?
The Socialync MCP server gives your assistant 28 tools to draft, schedule, publish, edit and cancel posts, upload media, read analytics and comments, find best times, and generate captions. Most work on every plan. Caption generation needs a paid plan. Posts reach Instagram, TikTok, YouTube, X, Facebook, LinkedIn, Threads, and Bluesky.

What to expect from them
- Text and image posts publish immediately to Instagram, Facebook, X, LinkedIn, Threads, and Bluesky. Video goes out as a scheduled post. X needs a paid plan, and Pinterest is not part of the MCP server.
- Caption generation is not on the free plan, while the MCP server itself is. Paid plans have it.
- Reading comments works for Instagram, YouTube, Threads, LinkedIn Company Pages on paid plans, and Bluesky. Replies work for Instagram, Threads, LinkedIn Company Pages on paid plans, and Bluesky. X, TikTok and Facebook comments, and YouTube replies, stay in the Socialync app.
- Editing a scheduled post changes its time, its caption (for every platform or one), the YouTube title, the first comment, or drops platforms. It cannot swap the media or add a platform. For that, cancel the post and schedule it again.
