Claude Integration with Seedream MCP
📘 Overview Guide: Using all 11 AceData Cloud MCP in Claude →
Seedream is an image generation model open-sourced by ByteDance, friendly to Chinese prompts, strong in both realistic and artistic styles, and fast in output, making it particularly suitable for illustrations, concept art, and posters. With MCP integrated, Claude can generate images in just a few seconds with a simple prompt in the chat box.
This article is a record of a hands-on test run on the Claude.ai web version: from adding the Connector, OAuth authorization, to generating a 16:9 watercolor-style phoenix image with a single prompt, complete with screenshots for easy reproduction.
¶ What is MCP?
MCP (Model Context Protocol) is an open protocol launched by Anthropic, allowing models like Claude to call external tools through standard interfaces. In simple terms: adding plugin capabilities to Claude.
AceData Cloud has encapsulated the core capabilities of Seedream into a remote MCP Server, allowing Claude to directly:
- Generate images from text descriptions (
seedream_generate_image) - Edit images / make partial modifications (
seedream_edit_image) - Query a single task (
seedream_get_task) - Batch query tasks (
seedream_get_tasks_batch) - List available models (
seedream_list_models) - List available image sizes (
seedream_list_sizes)
The entire integration requires just one URL, and the rest is handled by Claude.
¶ Adding Seedream MCP in Claude.ai Web Version
💡 The integration in Claude.ai web version is OAuth direct connection, no need to copy API Token. You only need an account that can log in to AceData Cloud (GitHub / Google / WeChat are all acceptable).
¶ 1. Open Connectors Settings
Log in to https://claude.ai, click on the avatar in the lower left corner → Settings → Customize → Connectors, or directly visit https://claude.ai/customize/connectors.
⚠️ The old entry
/settings/connectorshas been migrated to/customize/connectors. Visiting the old address will show a message "Connectors have moved to Customize."
¶ 2. Add Seedream MCP Server
Click the plus sign in the upper right corner → Add custom connector, and fill in the pop-up dialog:
| Field | Value |
|---|---|
| Name | Seedream (choose any name) |
| URL | https://seedream.mcp.acedata.cloud/mcp |
Click Add, and Claude will automatically discover all the tools exposed by the Server.
¶ 3. OAuth Authorization
Click Connect → Redirect to the AceData Cloud OAuth authorization page → Log in with your account and click Allow. If you haven't registered yet, go to https://platform.acedata.cloud to register, and you will receive free credits sufficient to run the demo in this article.
¶ 4. Check Tool List & Set Tools to Always Allow
After authorization, return to Claude.ai, open the Seedream Connector, and you will see 6 tools: seedream_generate_image, seedream_edit_image, seedream_get_task, seedream_get_tasks_batch, seedream_list_models, seedream_list_sizes.
⚙️ It is highly recommended to switch the Needs approval dropdown in the upper right corner to Always allow, otherwise, a confirmation box will pop up for each tool call. Generating an image usually triggers 2–4 tool calls (submission + multiple status queries), leading to a frustrating confirmation process.
¶ Test: Generating an Image with a Single English Prompt
Here is a real conversation I ran:
Prompt: Use Seedream to generate one image: a majestic phoenix rising from cherry blossoms, watercolor painting style, soft pink and gold palette, 16:9.
What Claude did upon receiving it:
- Automatically called
seedream_generate_image, including the prompt and 16:9 aspect ratio - Obtained the task ID and began polling
seedream_get_task - After about 20–40 seconds, received the final image (2848×1600)
- Posted the image link + text summary back to the chat box, along with a follow-up prompt asking "Do you need to change the style / adjust the composition?"
Here is a screenshot of the final chat result:
The actual generated final image (directly hosted on platform.cdn.acedata.cloud, available long-term):
💡 The image link is stable: AceData Cloud directly moves the images generated by Seedream to its own CDN (
platform.cdn.acedata.cloud/seedream/<id>.jpg), unlike direct connections to upstream CDNs that may expire. The link returned by Claude can be directly pasted into blogs, PPTs, or design drafts.
¶ More Uses (Same Connector)
Change the prompt to the following, and Claude will automatically select the appropriate tool:
Check available sizes before generating an image
List Seedream sizes first, then generate a 9:16 vertical poster of a Tokyo neon alley at midnight.
→ Claude first calls seedream_list_sizes to get a list of valid sizes, then uses seedream_generate_image to generate the image.
Edit Image / Partial Modification
Take that phoenix image and add a giant full moon in the background.
→ Claude calls seedream_edit_image, passing in the URL of the previous image for editing.
Direct Chinese Prompt Output
用 Seedream 生成一张图：江南雨夜的撑伞女子，水墨画风格，背景留白，9:16。
→ Seedream has a very stable understanding of Chinese prompts, and Claude will pass it in as is.
Batch Generate Multiple Candidates
Generate 4 variations of "cyberpunk Shanghai bund at rainy night", each in a different mood.
→ Claude sequentially calls generate 4 times, and finally uses seedream_get_tasks_batch to retrieve the results all at once.
¶ Frequently Asked Questions
Q: Why do I still need confirmation for new tools even after clicking Always allow? A: Always allow remembers on a tool-by-tool basis. Generate, Edit, Get Task, Get Tasks Batch, List Models, List Sizes are 6 different tools, and you only need to confirm each once.
Q: What should I do if my balance is insufficient?
A: The error message will include insufficient balance. Go to https://platform.acedata.cloud/console/coin to recharge, supporting Alipay / WeChat / Stripe / USDC. Generating a Seedream image usually consumes a few credits, and the free credits for new accounts are enough for several tests.
Q: What advantages does Seedream have compared to Midjourney / NanoBanana?
A: Seedream's Chinese prompt adherence is better than Midjourney; artistic quality is superior to NanoBanana; pricing is between the two. For Chinese posters, illustrations, and operational graphics, Seedream is recommended as a priority.
Q: Can it be used with other MCPs?
A: Yes. Claude.ai supports multiple connectors simultaneously. A sentence like "Use Seedream to create an ink wash painting of Jiangnan, then use Suno to write a matching ancient style song" allows Claude to arrange the image + music pipeline by itself. A complete list can be found at Claude × 11 MCP Overview.
Q: Can Claude Desktop and Claude Code be used this way too?
A: Yes. For details, see Claude Desktop + Seedream MCP and Claude Code + Seedream MCP.
