Claude and ChatGPT can write a week of posts in a minute. Neither one can post them on its own. What closes that gap is an MCP server from a social media scheduler: you connect it once, and the assistant gets tools like "create post", "list scheduled posts" and "delete post".

I build one of these schedulers (Fuxux), so I'll use it for the exact steps, but the setup is the same for any scheduler with a remote MCP server. A table of the others is at the end.

Most schedulers now let you sign in (OAuth) instead of pasting an API key. Prefer that: nothing secret ends up in a chat or a config file, and you can revoke access from the scheduler's settings.

**From the directory:**

`https://claude.ai/directory/fuxux`.
**By hand:** Settings → Connectors → add a custom connector, name it, paste the server URL (`https://www.fuxux.com/api/mcp`), then Connect and sign in.

The connection belongs to your Claude account, so it's there on web, desktop and mobile.

One command, then sign in from inside a session:

```
claude mcp add --transport http fuxux https://www.fuxux.com/api/mcp
```

Run `/mcp` in Claude Code, pick `fuxux`, authenticate, and your browser handles the sign-in. No key is stored anywhere.

**From the plugin directory:** search for the scheduler under Plugins (or open its listing), choose **Install plugin**, then **Connect**. ChatGPT opens a new tab where you sign in and allow access. In a chat, mention it with `@Fuxux` (or whatever the plugin is called).

**As a custom MCP server:** Plugins → Add → Create custom MCP server, paste the URL, leave authentication on OAuth. Custom MCP servers need a paid ChatGPT plan; directory plugins don't.

From each vendor's own docs, checked 25 October 2026 (tool counts change, so check before you pick):

| Tool | MCP server URL | How it connects | Tools | 
|---|---|---|---|
| Fuxux | [https://www.fuxux.com/api/mcp](https://www.fuxux.com/api/mcp) | Sign-in (any plan) or API key (paid plans) | 9 | 
| Buffer | [https://mcp.buffer.com/mcp](https://mcp.buffer.com/mcp) | Sign-in or personal API key | 20 | 
| Metricool | [https://ai.metricool.com/mcp](https://ai.metricool.com/mcp) | Sign-in or user token | 27 | 
| Pallyy | [https://app.pallyy.com/mcp](https://app.pallyy.com/mcp) | Sign-in or API key | 17 | 
| Typefully | [https://mcp.typefully.com/mcp](https://mcp.typefully.com/mcp) | Sign-in (recommended) or API key | Not stated | 
| Postiz | [https://mcp.postiz.com/mcp](https://mcp.postiz.com/mcp) | API key | 13 | 
| Post Bridge | [https://www.post-bridge.com/api/mcp/mcp](https://www.post-bridge.com/api/mcp/mcp) | Sign-in or API key | 16 | 
| Publer | [https://mcp.publer.com](https://mcp.publer.com) | Sign-in or API-key URL | Not stated | 
| Hootsuite | [https://mcp.hootsuite.com/perch](https://mcp.hootsuite.com/perch) (publishing) | Workspace sign-in | Not stated | 

More tools isn't automatically better: a scheduler with 27 tools can do more than post, but every tool description takes up room in the assistant's context. If you only want to draft and schedule, a small set is easier for the model to use correctly.

There's a longer comparison with prices and which ones are in each directory here: [https://www.fuxux.com/blog/social-media-schedulers-for-chatgpt-and-claude?ref=devto](https://www.fuxux.com/blog/social-media-schedulers-for-chatgpt-and-claude?ref=devto)

*I build Fuxux. The steps above are the same for any scheduler on the list; swap in its URL.*
