AI AGENT RECIPE

Turn a Twitch VOD into clips with an AI agent

Give the agent the link to a past broadcast. FastClip imports it and can mark the loud moments, where the audio volume jumps. You choose which ones to keep, and the agent cuts them as vertical clips with captions.

Paste this into your agent

Use FastClip. Import (paste the Twitch VOD link) and get its known moments. List the loud moments with their times. Then make a vertical clip with captions from (time) to (time), and give me the link.

Replace the parts in brackets. Your agent must be connected to FastClip first (next section).

Connect your agent once

In Claude Code, Codex, Cursor or VS Code, use a token. Sign in to FastClip and open Settings, then Agents. Create a token and copy it. FastClip shows it only one time. Then add FastClip's MCP server to your agent with the command or install link on the AI agents page. In an app that adds a custom MCP server by its address, add https://api.fastclip.it/mcp and sign in to FastClip when the app asks. No token is needed. A token, or an app you connect, can import videos, read transcripts and make clips. It cannot post, change your settings or delete anything.

What the agent calls, in order

These are FastClip's real MCP tools and arguments. The values are examples. Times are in seconds.

  1. 1. Import the VOD

    The agent adds the VOD to your account. A long VOD takes a while to import. The agent asks again until it can create clips.

    import_video { "url": "https://www.twitch.tv/videos/YOUR_VOD" }

  2. 2. Get the known moments

    The agent gets the loud moments (spikes in the audio volume), and the chapters if the VOD has them. The list can be empty.

    get_moments { "video_id": "VIDEO_ID" }

  3. 3. Cut the clip

    The agent cuts the range you chose in vertical 9:16. FastClip writes the captions from the speech in the clip.

    create_clip { "video_id": "VIDEO_ID", "start": 5321, "end": 5378, "format": "vertical", "captions": true }

  4. 4. Get the link

    The agent waits for the render and gives you the download link.

    get_clip { "clip_id": "CLIP_ID" }

What you get

Vertical clips with captions from your VOD, ready to download for TikTok, Shorts or Reels.

Where it works

Claude Code
Tested. We made clips from Claude Code with FastClip's server.
Codex
Tested. We made clips from Codex with FastClip's server.
Cursor
The setup follows Cursor's documented format for a remote server. We have not made a clip from Cursor yet.
VS Code
VS Code accepts the setup. We have not made a clip from VS Code yet.
Claude (web and desktop app)
Add FastClip as a custom connector with the server address https://api.fastclip.it/mcp and sign in to FastClip. We tested the sign-in with a generic client, not yet from the Claude app. FastClip is not in the Claude connector directory yet.
ChatGPT
In developer mode, add the server address https://api.fastclip.it/mcp and sign in to FastClip. We tested the sign-in with a generic client, not yet from ChatGPT. FastClip is not in the ChatGPT directory yet.
Grok
Add a custom connector with the server address https://api.fastclip.it/mcp and sign in to FastClip. We tested the sign-in with a generic client, not yet from Grok. FastClip is not in the Grok directory yet.

Limits

  • A Twitch VOD has no transcript in FastClip, so the agent cannot search what was said. It works from loud moments, chapters and the times you give.
  • A loud moment is only a jump in volume. It is a place to look, not a prediction of a good clip.
  • The agent cannot clip a live stream while it runs. Use the VOD after the stream.
  • On the free plan, Twitch links count as link imports: up to 20 a day.
  • You choose the moment. FastClip does not cut a batch of clips on its own and gives no virality scores. The agent makes the clips you ask for.
  • Clip length: 1 second to 5 minutes. Original keeps the frame of the video. Vertical is 9:16 at 1080 × 1920.
  • Speed limits: 6 new videos and 20 clips in 10 minutes for your account. The agent gets a clear error with the time to wait.
  • Your plan: the clips and imports an agent makes count toward your plan. The free plan has 100 finished clips and 50 YouTube or upload imports in total, and up to 30 finished clips a day.
  • If YouTube refuses the download: YouTube refuses many downloads from FastClip's servers. Then the import is queued and FastClip tries again by itself for about a day. You can also open the video in FastClip and upload the file. Waiting clips then continue from the file.

Questions

Does it read Twitch chat?

No. FastClip does not read chat. It uses the audio volume, the chapters and the times you give.

Which Twitch links work?

Links to past broadcasts (VODs) and Twitch clips.

Does the clip have captions without a transcript?

Yes. FastClip writes the captions from the speech in the clip itself. Check names before you post.
