One Prompt: Claude Code Publishes a Real Instagram Post via Custom MCP Server
Dull_Alps_8522 · reddit · 2026-10-12
A Reddit user demoed Claude Code publishing a real Instagram post from a single prompt via a custom FluxSocial MCP server — about 2 minutes, zero clicks:
- The unedited prompt: "Use FluxSocial MCP to post on @fluxsocial app's Instagram that this post was made by you, from one prompt."
- Claude autonomously found the right business account, drafted and picked a caption, generated the image, verified rendering, and published; the video is sped up 5x, and the post is still live on fluxsocial.app's Instagram.
- New accounts get 3,000 free credits; posting your own media is free, credits only cover AI generation. The author offers to explain the OAuth setup and how tools were split.
A reproducible combo: Claude Code + a custom MCP server wired to social publishing.
