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
Two options:
- OAuth (recommended) — run
/mcpinside Claude Code, selectpostsyncer, and click authenticate. You log in to PostSyncer once in the browser; no token to paste. - API token — create a token in the PostSyncer app (Settings → API) with the abilities you need (
workspaces,accounts,labels,campaigns,posts) and configure it as a Bearer token for thepostsyncerMCP server.
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 authorization when you choose the OAuth login flow. |
Credentials: either an OAuth grant issued during the login flow, or a PostSyncer API token you create yourself and configure as a Bearer token. The plugin never reads environment variables, files, or secrets from your machine, and the MCP server only accesses the PostSyncer workspaces the authenticated account can see.
