SeedreamMCP

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, including transparent-background Pro edits
Multiple Models — Seedream v5.0 (flagship), v4.5, and v4.0
Layer Decomposition — Split one image into a base plus up to 16 editable transparent PNG layers
Multi-Resolution — Pro 1K/1.5K/2K; Lite 2K/3K/4K; custom dimensions
Sequential Generation — Generate related images in sequence (5.0 Lite/4.5/4.0)
Web Search — Let 5.0 Lite use current web information when needed
Task Tracking — Monitor generation progress and retrieve results

Seedream 5.0 capability matrix

Capability	5.0 Pro	5.0 Lite
Single image generation/editing	Yes	Yes
Layer decomposition / transparent background	Yes	No
Sequential images / web search	No	Yes
Prompt optimization	standard, fast	standard
Preset sizes	1K, 1.5K, 2K	2K, 3K, 4K

MCP image tools submit asynchronously and return a task id. Use seedream_get_task until completion. For real-time NDJSON streaming, call the REST API or CLI rather than combining stream with MCP async submission.

Quick Start

1. Get Your API Token

Sign up at AceDataCloud Platform
Go to the API documentation page
Click "Acquire" to get your API token
Copy the token for use below

2. Use the Hosted Server (Recommended)

AceDataCloud hosts a managed MCP server — no local installation required.

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

All requests require a Bearer token. Use the API token from Step 1.

Claude.ai

Connect directly on Claude.ai with OAuth — no API token needed:

Go to Claude.ai Settings → Integrations → Add More
Enter the server URL: https://seedream.mcp.acedata.cloud/mcp
Complete the OAuth login flow
Start using the tools in your conversation

Claude Desktop

Add to your config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

config.json

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

3. Or Run Locally (Alternative)

If you prefer to run the server on your own machine:

server.ts

# Install from PyPI
pip install mcp-seedream-pro
# or
uvx mcp-seedream-pro

# Set your API token
export ACEDATACLOUD_API_TOKEN="your_token_here"

# Run (stdio mode for Claude Desktop / local clients)
mcp-seedream-pro

# Run (HTTP mode for remote access)
mcp-seedream-pro --transport http --port 8000

Claude Desktop (Local)

config.json

{
  "mcpServers": {
    "seedream": {
      "command": "uvx",
      "args": ["mcp-seedream-pro"],
      "env": {
        "ACEDATACLOUD_API_TOKEN": "your_token_here"
      }
    }
  }
}

Docker (Self-Hosting)

Terminal

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.
