README

PostSyncer Plugin

Schedule, publish, and analyze social media posts from Claude Code, Claude Cowork, Cursor, and Grok Build — across 11 platforms: X (Twitter), Instagram, Facebook, LinkedIn, TikTok, YouTube, Threads, Bluesky, Mastodon, Pinterest, and Telegram.

The plugin bundles the official PostSyncer MCP server (https://postsyncer.com/mcp) plus a skill that teaches Claude the full PostSyncer workflow: workspaces, connected accounts, posts (publish now / schedule / draft / repeat), threads, first comments, media library, campaigns, labels, comment moderation, and performance analytics.

Install

From the Claude plugin directory:

claude plugin install postsyncer

Or directly from this repo:

claude plugin marketplace add PostSyncer/claude-plugin
claude plugin install postsyncer@postsyncer

Cursor

Install from the Cursor Marketplace, or clone this repo into ~/.cursor/plugins/local/postsyncer and run Developer: Reload Window. The manifest lives in .cursor-plugin/plugin.json.

Codex

codex plugin marketplace add PostSyncer/claude-plugin

The Codex manifest lives in .codex-plugin/plugin.json; the plugin is also listed in the ChatGPT/Codex plugin directory as PostSyncer.

Gemini CLI

gemini extensions install https://github.com/PostSyncer/claude-plugin

Any MCP client

Point your client at https://postsyncer.com/mcp (Streamable HTTP). The server is published in the official MCP Registry as io.github.PostSyncer/postsyncer.

Grok Build

Install from the xAI plugin marketplace (postsyncer). The Claude-format manifest in .claude-plugin/plugin.json is used as-is.

Authenticate

Sign in with OAuth: run /mcp inside Claude Code, select postsyncer, and click authenticate. You log in to PostSyncer once in the browser, and Claude stores and refreshes the session for you.

Try it

"List my connected social accounts"
"Schedule a post to LinkedIn and X for tomorrow at 9am announcing our new feature"
"Upload these product shots and draft an Instagram carousel with the link in a first comment"
"How did last week's posts perform across all my workspaces?"
"Repeat this post every Monday for a month"

What's included

Component	Description
MCP server	Remote HTTP server at `postsyncer.com/mcp` with ~50 tools mirroring PostSyncer REST API v1
`postsyncer` skill	Workflow guidance: discovery, media prep, posting rules, threads, first comments, scheduling, repeats, analytics, moderation

Network and permissions

This plugin ships no scripts, hooks, or local binaries. Its only component besides the skill file is a remote MCP server:

Endpoint	Purpose
`https://postsyncer.com/mcp`	The PostSyncer MCP server (Streamable HTTP). All tool calls go here.
`https://postsyncer.com/oauth/*`	OAuth 2.0 sign-in.

Sign-in is OAuth only. The MCP server only accesses the PostSyncer workspaces the signed-in account can see.
