Let your agents make the clips

Connect Roundclip to Claude, Cursor or any MCP client, or call the API from your own app. Send a link and get back captioned vertical clips with download links. It uses the minutes on your account, same as the app.

Your API keys

Connect an agent with MCP

Your agent gets four tools: create_clips, get_clips, list_videos and get_balance. Ask it something like “make 5 clips from this video and give me the download links”.

Start a video, then check it every minute or so until its status is done. Most videos take 2 to 6 minutes.
