MCP Seedream

A Model Context Protocol (MCP) server for AI image generation and editing using ByteDance's Seedream models through the AceDataCloud API.

Generate and edit AI images directly from Claude, VS Code, or any MCP-compatible client.

Features

• Text-to-Image Generation — Create high-quality images from text prompts (Chinese & English)
• Image Editing — Modify existing images with AI (style transfer, background change, virtual try-on)
• Multiple Models — Seedream v4.5 (flagship), v4.0 (balanced), v3.0 T2I, SeedEdit v3.0 I2I
• Multi-Resolution — 1K, 2K, 4K, adaptive, and custom dimensions
• Seed Control — Reproducible results with seed parameter (v3 models)
• Sequential Generation — Generate related images in sequence (v4.5/v4.0)
• Streaming — Progressive image delivery (v4.5/v4.0)
• Task Tracking — Monitor generation progress and retrieve results

Quick Start

1. Get API Token

Get your API token from AceDataCloud Platform:

1. Sign up or log in
2. Navigate to Seedream Images API
3. Click "Acquire" to get your token

2. Install

# Install from PyPI
pip install mcp-seedream-pro

# Or clone and install locally
git clone https://github.com/AceDataCloud/MCPSeedream.git
cd MCPSeedream
pip install -e .

3. Configure

# Copy example environment file
cp .env.example .env

# Edit with your API token
echo "ACEDATACLOUD_API_TOKEN=your_token_here" > .env

4. Run

# Run the server
mcp-seedream-pro

# Or with Python directly
python main.py

Claude Desktop Integration

Add to your Claude Desktop configuration:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "seedream": {
      "command": "mcp-seedream-pro",
      "env": {
        "ACEDATACLOUD_API_TOKEN": "your_api_token_here"
      }
    }
  }
}

Or if using uv:

{
  "mcpServers": {
    "seedream": {
      "command": "uv",
      "args": [
        "run",
        "--directory",
        "/path/to/MCPSeedream",
        "mcp-seedream-pro"
      ],
      "env": {
        "ACEDATACLOUD_API_TOKEN": "your_api_token_here"
      }
    }
  }
}

Remote HTTP Mode (Hosted)

AceDataCloud hosts a managed MCP server that you can connect to directly — no local installation required.

Endpoint: https://seedream.mcp.acedata.cloud/mcp

All requests require a Bearer token in the Authorization header. Get your token from AceDataCloud Platform.

Claude Desktop (Remote)

{
  "mcpServers": {
    "seedream": {
      "type": "streamable-http",
      "url": "https://seedream.mcp.acedata.cloud/mcp",
      "headers": {
        "Authorization": "Bearer your_api_token_here"
      }
    }
  }
}

Cursor / VS Code

In your MCP client settings, add:

• Type: streamable-http
• URL: https://seedream.mcp.acedata.cloud/mcp
• Headers: Authorization: Bearer your_api_token_here

cURL Test

# Health check (no auth required)
curl https://seedream.mcp.acedata.cloud/health

# MCP initialize (requires Bearer token)
curl -X POST https://seedream.mcp.acedata.cloud/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json" \
  -H "Authorization: Bearer your_api_token_here" \
  -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-03-26","capabilities":{},"clientInfo":{"name":"test","version":"1.0"}}}'

Self-Hosting with Docker

docker pull ghcr.io/acedatacloud/mcp-seedream-pro:latest
docker run -p 8000:8000 ghcr.io/acedatacloud/mcp-seedream-pro:latest

Clients connect with their own Bearer token — the server extracts the token from each request's Authorization header and uses it for upstream API calls.
