## Claude Desktop Quick Installation
Heuristic fallback — verify the package name and runner against the repository README before running it. Uses `npx` (confidence: low):

```json
"mcpServers": {
  "postsyncer": {
    "command": "npx",
    "args": ["-y","postsyncer"]
  }
}
```

## Documentation & 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:

```bash
claude plugin install postsyncer
```

Or directly from this repo:

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

### Cursor

Install from the [Cursor Marketplace](https://cursor.com/marketplace), or clone this repo into `~/.cursor/plugins/local/postsyncer` and run **Developer: Reload Window**. The manifest lives in `.cursor-plugin/plugin.json`.

### Codex

```bash
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

```bash
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](https://registry.modelcontextprotocol.io) as `io.github.PostSyncer/postsyncer`.

### Grok Build

Install from the [xAI plugin marketplace](https://github.com/xai-org/plugin-marketplace) (`postsyncer`). The Claude-format manifest in `.claude-plugin/plugin.json` is used as-is.

## Authenticate

Two options:

1. **OAuth (recommended)** — run `/mcp` inside Claude Code, select `postsyncer`, and click authenticate. You log in to PostSyncer once in the browser; no token to paste.
2. **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 the `postsyncer` MCP 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.
