Modelflare MCP Server

Image and video generation for any MCP client — Claude Desktop, Cursor, Gemini CLI and more — with one Modelflare Smart API Key for every image and video model available to your account.

用一个 Modelflare Smart API Key，在任意 MCP 客户端里调用你账号可用的全部图像和视频模型。

mcp-name: io.github.castaly-ai/mcp-server

Configure / 配置

Add the server to your MCP client:

{
  "mcpServers": {
    "modelflare": {
      "command": "npx",
      "args": ["-y", "@modelflare/mcp-server"],
      "env": {
        "MODELFLARE_API_KEY": "<your Smart API Key>"
      }
    }
  }
}

Variable	Value
MODELFLARE_API_KEY	your Smart API Key (required)
MODELFLARE_BASE_URL	global → https://modelflare.dev/v1 (default) · china → https://origin.modelflare.dev/v1 · or a custom URL
MODELFLARE_OUTPUT_DIR	where images and videos are saved (default ./modelflare-output)
MODELFLARE_LOCALE	en (default) or zh for error messages

Claude Desktop: download modelflare-mcp-<version>.mcpb from Releases and open it; Claude Desktop asks for the API key, base URL and output folder. modelflare-mcp-<version>-smithery.mcpb is the same bundle with each tool's inputSchema in the manifest, as Smithery requires. node build-mcpb.mjs rebuilds both.

Tools / 工具

Tool	What it does
list_models	Image and video models your key can call, each with the docs page holding its exact request fields. kind: "text" lists text models.
generate_image	Generates an image, or edits one with edit: true, and saves it. Gemini image models use generateContent; the others use the Images API.
create_video	Starts an asynchronous video task and returns its task ID.
get_video_status	Status and progress of a video task.
download_video	Saves a finished video; can wait up to 300 seconds first.

Model-specific fields go in parameters (images) or request (videos) and are sent unchanged. The model list comes from your key, so new models appear without editing the key. Generated results are saved right away because result URLs expire.

Calls are billed to your Modelflare balance by actual usage; see https://modelflare.dev/usage-logs.

Troubleshooting / 常见问题

• 401: the key is missing or invalid. Create a Smart API Key at https://modelflare.dev/keys.
• model_not_found: a regular key only calls the models of its own group. A Smart API Key calls every model available to your account. If you already use a Smart API Key, that model is not available to your account right now.
• 403 insufficient_user_quota: top up at https://modelflare.dev/billing.
