Caption a video from an MCP client in three tool calls (no sign-up)

Here is a captioned version of the video from the MCP client using three tool calls (no sign-up required):

To caption a video without creating an account, follow these three simple steps. First, use the keyless remote MCP endpoint at https://api.awesomevideoeditor.com/mcp. This URL works with many JSON-friendly clients like Streamable HTTP for initializing the process.

Next, create a free trial key by calling the create_key tool (or use the anonymous REST path directly). This grants you welcome credits for testing a short clip. No email verification is needed for the agent path in this case.

Finally, call the caption_video tool with a public MP4 URL. The service will return a job status, along with a styled MP4 video with captions burned-in, as well as separate SRT/VTT and JSON transcripts. The pricing details are available at https://awesomevideoeditor.com/v1/pricing (currently 5 credits per audio minute for captions, plus 2 credits for translation).

For automation in n8n instead of manual calls, there is an importable workflow available that requires no key baked in. This allows agents to caption videos efficiently using the AwesomeVideo MCP without needing to sign up.
