Vieews

Upload a video or photo once and publish it, now or on a schedule, to your YouTube, Instagram and TikTok accounts. Includes an MCP server so an AI agent (Claude Code, Claude Desktop, Cursor…) can upload and post for you.

Stack: Next.js 16 (App Router) · React 19 · Tailwind 4 · Clerk · Supabase (Postgres + Storage) · Inngest · Vercel

Start with SETUP.md: it walks through every account and key you need.

How it works

• Upload: the server hands the browser a one-time signed upload URL and the file goes straight to a private Supabase Storage bucket, so large videos never pass through a Vercel function.
• Publish: creating a post sends an Inngest event. publish-post waits until the scheduled time, then fans out one publish-target job per account. Each job streams the file to the platform in chunks (YouTube resumable upload, TikTok chunked FILE_UPLOAD) or hands Instagram a short-lived signed URL, polls processing, and records the live link. Every step is retried and resumable.
• Accounts: OAuth tokens are encrypted with AES-256-GCM before they're stored and refreshed automatically. Failed refreshes flag the account for reconnecting.
• MCP: /api/mcp exposes list_accounts, get_platform_requirements, create_media_upload, finalize_media_upload, import_media_from_url, create_post, get_post, list_posts, cancel_post and retry_post_target, authenticated with API keys you create in the app.
