The writeup compares nine schedulers, including Buffer, Metricool, Pallyy and Hootsuite, by MCP server URL, connection method and tool count, and notes that larger tool sets consume more of the model's context. The author recommends OAuth sign-in over pasted API keys so credentials stay out of chats and config files.", "body_md": "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\".\n\nI 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.\n\nMost 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.\n\n**From the directory:**\n\n`https://claude.ai/directory/fuxux`.\n**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.\n\nThe connection belongs to your Claude account, so it's there on web, desktop and mobile.\n\nOne command, then sign in from inside a session:\n\n```\nclaude mcp add --transport http fuxux https://www.fuxux.com/api/mcp\n```\n\nRun `/mcp` in Claude Code, pick `fuxux`, authenticate, and your browser handles the sign-in. No key is stored anywhere.\n\n**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).\n\n**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.\n\nFrom each vendor's own docs, checked 25 October 2026 (tool counts change, so check before you pick):\n\n| Tool | MCP server URL | How it connects | Tools | \n|---|---|---|---|\n| Fuxux | [https://www.fuxux.com/api/mcp](https://www.fuxux.com/api/mcp) | Sign-in (any plan) or API key (paid plans) | 9 | \n| Buffer | [https://mcp.buffer.com/mcp](https://mcp.buffer.com/mcp) | Sign-in or personal API key | 20 | \n| Metricool | [https://ai.metricool.com/mcp](https://ai.metricool.com/mcp) | Sign-in or user token | 27 | \n| Pallyy | [https://app.pallyy.com/mcp](https://app.pallyy.com/mcp) | Sign-in or API key | 17 | \n| Typefully | [https://mcp.typefully.com/mcp](https://mcp.typefully.com/mcp) | Sign-in (recommended) or API key | Not stated | \n| Postiz | [https://mcp.postiz.com/mcp](https://mcp.postiz.com/mcp) | API key | 13 | \n| Post Bridge | [https://www.post-bridge.com/api/mcp/mcp](https://www.post-bridge.com/api/mcp/mcp) | Sign-in or API key | 16 | \n| Publer | [https://mcp.publer.com](https://mcp.publer.com) | Sign-in or API-key URL | Not stated | \n| Hootsuite | [https://mcp.hootsuite.com/perch](https://mcp.hootsuite.com/perch) (publishing) | Workspace sign-in | Not stated | \n\nMore 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.\n\nThere'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)\n\n*I build Fuxux. The steps above are the same for any scheduler on the list; swap in its URL.*", "url": "https://wpnews.pro/news/how-to-schedule-social-media-posts-from-claude-or-chatgpt-with-mcp-2026", "canonical_source": "https://dev.to/fuxuxscheduler/how-to-schedule-social-media-posts-from-claude-or-chatgpt-with-mcp-2026-3f33", "published_at": "2026-11-05 18:32:37+00:00", "updated_at": "2026-11-05 18:49:42.245557+00:00", "lang": "en", "topics": ["ai-agents", "agent-protocols", "ai-tools", "ai-products"], "entities": ["Fuxux", "Claude", "ChatGPT", "Anthropic", "OpenAI", "Buffer", "Metricool", "Hootsuite"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/how-to-schedule-social-media-posts-from-claude-or-chatgpt-with-mcp-2026", "markdown": "https://wpnews.pro/news/how-to-schedule-social-media-posts-from-claude-or-chatgpt-with-mcp-2026.md", "text": "https://wpnews.pro/news/how-to-schedule-social-media-posts-from-claude-or-chatgpt-with-mcp-2026.txt", "jsonld": "https://wpnews.pro/news/how-to-schedule-social-media-posts-from-claude-or-chatgpt-with-mcp-2026.jsonld"}}
