RunAPI MCP server for Seedream: create tasks, poll status, check pricing.

Source code Documentation

Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package @runapi.ai/seedream-mcp
Claude Code 
claude mcp add seedream-mcp -e 'RUNAPI_API_KEY=<your runapi_api_key>' -- npx -y @runapi.ai/seedream-mcp@0.3.1
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "seedream-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "@runapi.ai/seedream-mcp@0.3.1"
            ],
            "env": {
                "RUNAPI_API_KEY": "<your runapi_api_key>"
            }
        }
    }
}

Environment variables

  • RUNAPI_API_KEY secret Optional RunAPI API key for headless hosts. Interactive MCP hosts can use the login tool, which writes shared RunAPI config.

RunAPI Seedream MCP Server

Seedream API access for AI agents: run image generation operations, poll asynchronous results, and check pricing through one focused MCP server.

Works with Claude Code, Codex, Cursor, Windsurf, VS Code, Roo Code, and any MCP-compatible host.

Why This Package?

@runapi.ai/seedream-mcp is a focused Model Context Protocol server for the Seedream model line on RunAPI. It gives MCP-compatible assistants direct access to 3 endpoints and 9 model variants without loading the full RunAPI catalog.

Use this per-model server when an agent should stay scoped to Seedream. Use @runapi.ai/mcp when one assistant should discover every RunAPI model line.

Install

Add it to Claude Code:

claude mcp add seedream -s user -- npx -y @runapi.ai/seedream-mcp

Use project scope when the server should be shared with a repository:

claude mcp add seedream -s project -- npx -y @runapi.ai/seedream-mcp

Codex, Cursor, Windsurf, VS Code, Roo Code, and other MCP hosts can use the same stdio command:

{
  "mcpServers": {
    "seedream": {
      "command": "npx",
      "args": ["-y", "@runapi.ai/seedream-mcp"]
    }
  }
}

check_pricing works before sign-in. For task creation and status polling, ask your assistant to call the login tool. It opens a browser login and saves credentials to ~/.config/runapi/config.json, the same file used by runapi login. Headless and CI hosts can still set RUNAPI_API_KEY before starting the MCP host.

Ready-made examples are in examples/ for Claude, Cursor, Windsurf, VS Code, and Roo Code.

Tools

ToolAuthPurpose
decompose_layersYesCreate a Seedream decompose layers task and optionally wait for a terminal status. Returns the task id, status, and output URLs.
edit_imageYesCreate a Seedream edit image task and optionally wait for a terminal status. Returns the task id, status, and output URLs.
text_to_imageYesCreate a Seedream text to image task and optionally wait for a terminal status. Returns the task id, status, and output URLs.
get_taskYesFetch the current status and latest payload for an existing task.
check_pricingNoLook up current pricing for a Seedream model and endpoint.

Models

Seedream covers 9 model variants across 3 endpoints. Each tool accepts the models listed for it:

ToolModels
decompose_layersseedream-5-pro-layer-decomposition
edit_imageseedream-4.5-edit, seedream-5-lite-edit, seedream-5-pro-edit, seedream-v4-edit
text_to_imageseedream-4.5-text-to-image, seedream-5-lite-text-to-image, seedream-5-pro-text-to-image, seedream-v4-text-to-image

Model availability can change between releases. Use check_pricing or the Seedream model page for the current catalog view.

Agent Prompts

Ask your assistant in natural language; it can inspect pricing, create the task, and return the task id plus output URLs.

Create a task
Run a Seedream decompose layers task with RunAPI.

The assistant can call check_pricing, then decompose_layers, and return the task id, status, and output URLs.

Submit without waiting
Create the task but don't wait for it to finish.

The assistant calls the create tool with wait: false and returns the task id. Check on it later with get_task.

Check pricing before creating
Check current Seedream pricing, then create the task if it matches my request.

The assistant calls check_pricing and can link to the Seedream model page for the canonical catalog entry.

Configuration

The server resolves auth in this order:

  1. RUNAPI_API_KEY environment variable, useful for headless and CI hosts
  2. ~/.config/runapi/config.json, created by the MCP login tool or runapi login
  3. No key, which still allows check_pricing

The config file is normally managed by login. A pre-provisioned headless config can use:

{
  "apiKey": "your_runapi_key"
}

Do not commit real API keys.
