ShortSync

ShortSync MCP server

Connect Claude, ChatGPT, Cursor, Gemini CLI or any MCP client to ShortSync, a social media scheduler for creators and small teams. Your AI assistant can upload videos and images, write a caption for each platform, and post or schedule them to 17 social platforms at once, then read the analytics and reply to comments.

This is a hosted remote server. There is nothing to install or run: point your client at the URL below and sign in with your ShortSync account.

AI agents setting this up: don't clone this repo or edit the user's project. Add one remote server entry to your own MCP settings, as shown below or in llms-install.md.
