VS Code + Seedream MCP

Developers who have created posters know a common pain point: Midjourney and Flux have poor support for Chinese. If you ask it to write "限时优惠," it may produce garbled text or awkward strokes.

Seedream is an AI image model developed by ByteDance, and rendering Chinese text is its strong suit. If you say, "Add the red words '限时优惠' to the top right corner of the image," it can really do that.

If your target audience is Chinese users, Seedream is a more suitable choice than Midjourney.

Open the Ace Data Cloud application list, go to the available applications, and copy the API Key.

Step 4: Verify Connection

  2. Directly state your request and mention seedream, for example: Use seedream to help me complete this task
  3. The first call will automatically go to this plugin and use the API Key you saved

Advanced: Manual mcp.json (Optional)

If you prefer manual configuration, you can also write .vscode/mcp.json in your project:

{
  "servers": {
    "seedream": {
      "type": "http",
      "url": "https://seedream.mcp.acedata.cloud/mcp",
      "headers": {
        "Authorization": "Bearer ${input:acedata-api-key}"
      }
    }
  },
  "inputs": [
    {
      "id": "acedata-api-key",
      "type": "promptString",
      "description": "Ace Data Cloud API Key",
      "password": true
    }
  ]
}

Advantages of Seedream in Chinese Scenarios

Promotional Image for a Tech Salon

Your team is organizing an offline tech sharing event and needs a poster to send to the group:

> Generate a tech salon poster with the title "AI Engineering Practice Sharing Session," subtitle "January 18, 2025 · Beijing," with a dark gradient background, a sense of technology, and leave space at the bottom for a QR code

Seedream's seedream_generate_image renders Chinese titles with quality far superior to other models—clear fonts, reasonable layout, and no garbled text.

Creating Marketing Materials for Domestic Products

Your app targets domestic users and needs a set of holiday marketing images:

> Generate a Spring Festival themed app splash screen with big red lanterns and golden "Happy New Year," festive but not tacky, in a modern design style

Eastern aesthetics are a strong point of Seedream's training data—elements of national style, festive atmosphere, and traditional color matching are all well captured.

Modifying Existing Materials

You have an English banner and want to quickly create a Chinese version:

> Replace the English "Get Started" in this image with the Chinese "立即体验," keeping the font size and position consistent
