How to Generate Short Videos from Claude.ai with a Seedance MCP Connector

Sometimes the fastest way to prototype a video idea is not to open a separate generation dashboard, but to let your assistant create and poll the task while you stay in the conversation.

This guide shows how the Seedance MCP connector works inside Claude.ai, based on the Ace Data Cloud documentation. The workflow is practical: add one remote MCP URL, authorize with OAuth, ask Claude to list available models and resolutions, then generate a short video and poll the task until a URL is returned.

What you can do

Seedance is ByteDance’s Doubao video generation family, exposed here through a remote MCP server. Once connected to Claude.ai, the documented tools include:

Tool	Purpose
seedance_generate_video	Generate a video from a text prompt
seedance_generate_video_from_image	Animate an image into a video
seedance_get_task	Query a single generation task
seedance_get_tasks_batch	Query multiple tasks together
seedance_list_actions	List supported actions
seedance_list_models	List available models
seedance_list_resolutions	List valid resolutions

The important part is that Claude can call the list tools first, choose valid values, submit a task, and then poll with seedance_get_task. You do not need to manually copy model names between pages.

How it works

Claude.ai supports custom MCP connectors. For Seedance, the connector uses OAuth direct connection, so the guide does not require copying an API token into Claude. You add a custom connector with this URL:

https://seedance.mcp.acedata.cloud/mcp

Enter fullscreen mode Exit fullscreen mode

In Claude.ai, open settings for connectors, add a custom connector, and use a name such as:

Seedance

Enter fullscreen mode Exit fullscreen mode

Then fill the URL field with:

https://seedance.mcp.acedata.cloud/mcp

Enter fullscreen mode Exit fullscreen mode

After clicking connect, Claude redirects to Ace Data Cloud for OAuth authorization. Once approved, the connector appears in Claude with the Seedance tools listed above.

Set tool approval intentionally

Video generation usually involves more than one tool call. A careful prompt may ask Claude to:

1. call seedance_list_models,
2. call seedance_list_resolutions,
3. submit with seedance_generate_video,
4. poll with seedance_get_task.

The source guide recommends setting tool approval to “Always allow” for the connector if you are comfortable with the workflow. Otherwise, Claude may ask for confirmation several times during one generation. If you are testing a new prompt or model, leaving approvals on can still be a reasonable safety choice.

Run a minimal text-to-video test

A good first prompt should be specific about cost, duration, and resolution constraints without pretending you already know every valid option. The documentation uses this style:

Use Seedance to generate one short video. First list models and resolutions, pick the FASTEST/CHEAPEST model (e.g. lite/fast variant) and the LOWEST resolution. Use the SHORTEST duration (4-5 seconds). Subject: a fluffy white kitten chasing a red leaf falling in a sunny garden, side view, simple background.

Enter fullscreen mode Exit fullscreen mode

In the documented run, Claude first called seedance_list_models and seedance_list_resolutions, then selected:

doubao-seedance-1-0-pro-fast-251015
480p
4 seconds
16:9
24fps

Enter fullscreen mode Exit fullscreen mode

Then it submitted the generation with seedance_generate_video and used seedance_get_task to wait for the result.

That order is worth copying. Instead of hard-coding values that may become stale, let the assistant ask the MCP server for valid options first.

Animate an existing image

The same connector also supports image-to-video generation. The documented tool for that is:

seedance_generate_video_from_image

Enter fullscreen mode Exit fullscreen mode

A prompt can be as direct as:

Take this image https://cdn.acedata.cloud/foo.png and animate it with Seedance fast model: slow zoom-in, soft wind, 4 seconds, 480p.

Enter fullscreen mode Exit fullscreen mode

This is useful for product mockups, social clips, or turning a static storyboard frame into a short motion test. The important fields to keep explicit are the source image URL, motion direction, duration, and resolution.

Compare variants before committing

When you are not sure which model variant fits a scene, use Claude as a small experiment runner. For example:

Generate the same prompt "a samurai walking through bamboo forest in mist" with Seedance pro AND fast variants at 720p, 5 seconds, and tell me which one looks better.

Enter fullscreen mode Exit fullscreen mode

Claude can call seedance_list_models, submit separate tasks, then compare the returned videos. This is especially useful during prompt exploration, where you care more about learning what works than producing the final asset in one shot.

Batch a few lightweight ideas

For early ideation, batch generation can save time. The documented batch-style prompt is:

Generate 3 Seedance videos in parallel: 1) puppy on beach, 2) hot air balloon at sunrise, 3) coffee being poured. All 480p, 4s, fast model. Then return all three URLs.

Enter fullscreen mode Exit fullscreen mode

Here Claude can submit multiple tasks and use:

seedance_get_tasks_batch

Enter fullscreen mode Exit fullscreen mode

to check them together. I would keep batch prompts small at first: three short clips are easier to review than ten, and the feedback loop stays manageable.

A builder-friendly workflow

A practical workflow for short-form video prototyping looks like this:

1. Start with 480p and 4 seconds.
2. Ask Claude to list models and resolutions before choosing values.
3. Generate one simple shot with clear subject, motion, background, and framing.
4. Review the result and change only one variable at a time.
5. Batch two or three variants once the prompt direction is stable.

This keeps the assistant useful without turning the process into a black box. You still decide the creative direction; the MCP connector handles valid parameters, task submission, and polling.
