About postoncehq/postonce-skills
The official PostOnce social media skills and MCP server for Claude, ChatGPT, Cursor and Codex. Your AI agent writes a native post for each platform, crossposts it to LinkedIn, X, Threads, Bluesky, Facebook, Instagram, TikTok, YouTube and Pinterest in one request, and plans and schedules weeks of content, all through each platform's official API. There's no scraping, no browser automation and no developer apps to set up.
