Server details

Identifier: app.shortsync/shortsync
Transport: Streamable HTTP
Runtime: Web executable
Trust: Verified
Published: Oct 16, 2026

Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to shortsync.app, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Hosted ShortSync MCP server that lets an AI assistant draft, schedule and publish social posts to 17 platforms, then read analytics and reply to comments.

What you can do: Check account, workspaces, connected platforms, Pinterest boards and Discord channels
Upload videos and images, create carousels and manage library folders
Create and edit post drafts, batch updates, replace media and set thumbnails
Schedule, batch schedule, publish now or cancel posts, and list scheduled posts
Read workspace, folder, video and post analytics and sync analytics data
List comments and DMs, reply to comments, like, mark seen or spam
When to use it: Useful when you manage social accounts for yourself or a small team and want an assistant to prepare, schedule and publish multi-platform posts, review performance, or handle inbox replies without switching between dashboards.
Requirements: A remote Streamable HTTP endpoint; nothing to install. A ShortSync account signed in through OAuth 2.1 in the browser, with consent on the first tool call. Works on every plan, including the free plan with 5 uploads a month.

Before you install

The assistant can publish, schedule and cancel posts and reply to comments, which is visible to your audience; review before approving. It reads analytics and inbox messages from connected accounts. Access tokens last 1 hour and refresh tokens 30 days, and access can be revoked in ShortSync settings. Calls are limited to 60 a minute per token.

Installation

In SourceWeft

Open ShortSync in the dashboard and add it to a workspace.
Connect the required credentials. They are stored privately and never shown on public pages.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/app.shortsync%2Fshortsync/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

[ShortSync]

ShortSync MCP server

[ShortSync MCP server on Glama]

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.

Tools

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.

85% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
