ZapCap MCP server

This is a small helper that connects your AI assistant to ZapCap, a service that adds captions and extra footage (called B-roll) to videos. Once it is set up, you can just describe the captions you want in normal words instead of filling in forms. It is handy for anyone who edits videos and wants the boring caption work done faster.

What this MCP server does

You tell your AI which video you want to work on, either a file on your computer or a link. Your AI passes that to this helper, which uploads the video to ZapCap. Then your AI asks ZapCap for the list of caption styles (called templates) and creates a processing task with the look you described, like green highlighted words or a certain amount of B-roll. Finally, your AI checks the task progress and tells you when the captioned video is ready.

What you can do with it

• Upload a video file from your computer to ZapCap
• Upload a video by pasting a link instead of a file
• See the list of caption templates ZapCap offers

Try asking your AI

• “Upload my video at /Users/me/videos/interview.mp4 to ZapCap”
• “Show me the caption templates ZapCap has”
• “Add green highlighted subtitles with 40 percent B-roll using the viral template”
• “How is my ZapCap task going?”

What it gives back to you

You get answers in the chat, not files. When you upload a video, your AI tells you the video ID. When you ask for templates, you get a list of names and IDs. When you create a task, you get a task ID, and when you check progress, you get a status update like processing or done.
