I Built an AI Video Ad Generator with Claude + MCP — Here's the Architecture

I wanted to see what happens when you give Claude real tools — not a weather API, not a todo app — but image generation, voice synthesis, video composition, and quality grading. Could it orchestrate a full creative pipeline from a single prompt? The result is AdVideo Creator : an open-source CLI where you type "create a 15-second TikTok ad for artisan coffee" and get back a finished .mp4 file. Script, images, voiceover, music, transitions, subtitles — all generated and composed automatically. Here's how it works under the hood. The Problem: Claude Has No Hands Claude can write an excellent marketing script. Give it a product, a target audience, and a tone — it'll produce a hook, emotional beats, and a call to action that actually works. Then what? You still need images. A voiceover. Background music. Video editing. Platform-specific export. And if the script doesn't fit the timing after you lay it over the visuals, you go back to Claude, ask for a rewrite, and start the cycle again. Th
