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.
| 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.
