Overview

The social-brain MCP server integrates four social platforms—Instagram, Facebook, Twitter/X, and YouTube—into Claude workflows. Users connect accounts once to post content, generate captions, access analytics, schedule publications, and more, all via API tools without leaving the conversation.

Free tier provides Instagram/Facebook stats, Twitter search, YouTube stats, and hashtag suggestions. Paid tier ($29/mo) unlocks publishing to all platforms, AI captions, content calendars, competitor analysis, and viral content ideas across 19 tools.
