Sync from Docs

When invoked by the sync workflow, the Docs repo is checked out at _docs/. Your job:

1. Source of truth — _docs/openapi/seedream.json is the OpenAPI spec for the SeedreamMCP API.
2. Compare models — The Literal types in core/types.py must match the spec's model enum. Add/remove as needed.
3. Compare parameters — Each @mcp.tool() function's parameters should match the corresponding OpenAPI endpoint.
4. Update defaults — If a new model becomes the recommended default, update the default in core/types.py.
5. Update README — Keep the model table and feature list current.
6. Add tests — For new tools or parameters, add test cases in tests/.
7. PR title — Use format: sync: <description> [auto-sync]

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 with AI (style transfer, background change, virtual try-on)
• Multiple Models — Seedream v5.0 (flagship), v4.5, v4.0, v3.0 T2I, SeedEdit v3.0 I2I
• Multi-Resolution — 1K, 2K, 3K, 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

Tool Reference

Quick Start

1. Get Your API Token

1. Sign up at AceDataCloud Platform
2. Go to the API documentation page
3. Click "Acquire" to get your API token

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:

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

3. Or Run Locally (Alternative)

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

# 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)

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

Docker (Self-Hosting)

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.
