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.

Platforms

YouTube, TikTok, Instagram, Facebook, Snapchat, X, Threads, LinkedIn, Bluesky, Pinterest, Mastodon, Telegram, Discord, Tumblr, Pixelfed, Google Business Profile and Reddit. Videos, images, carousels and text posts.

Cline

Nothing to clone or build. In Cline open MCP Servers → Add Remote Server: name shortsync, URL https://www.shortsync.app/api/mcp, transport Streamable HTTP. Or click Edit Configuration on that screen (current versions use ~/.cline/data/settings/cline_mcp_settings.json) and add:

{

"mcpServers": { "shortsync": { "type": "streamableHttp", "url": "https://www.shortsync.app/api/mcp", "disabled": false, "autoApprove": [] } } }

The first ShortSync tool call opens a browser to sign in; click Allow. AI agents: see llms-install.md.

Cursor, VS Code, Windsurf and other clients

Add this to your MCP config (.cursor/mcp.json, .vscode/mcp.json, claude_desktop_config.json, and so on):

{

"mcpServers": { "shortsync": { "type": "http", "url": "https://www.shortsync.app/api/mcp" } } }

What it can do

Prompts: status_check, post_everywhere, weekly_report, reply_to_comments and connect_account are ready-made starting points in clients that show MCP prompts.

Ask your client to run tools/list for the current set, or read the server card. Every tool has read-only or destructive hints, so clients can ask before anything is posted.

Example prompts

• "Upload this video and schedule it to TikTok, YouTube Shorts and Instagram Reels for Friday 9:00, with a different caption for each."
• "Turn these 5 images into a carousel and post it to Instagram and LinkedIn now."
• "Which of last month's posts got the most views, and on which platform?"
• "Reply to the unanswered comments from this week."

Limits and privacy

• Access tokens last 1 hour and refresh tokens 30 days. Revoke access any time in ShortSync under Settings → API & MCP.
• Tool calls are limited to 60 a minute per token, on top of your plan's monthly quota.
• Privacy policy · Terms
