This MCP server provides an interface for generating high-quality images using the Flux.1 Schnell model via Together AI, implementing the Model Context Protocol (MCP) standard for a consistent integration experience.
You can install the server using npm:
npm install together-mcp
Or run it directly without installation:
npx together-mcp@latest
To add this to your MCP server configuration:
{
"mcpServers": {
"together-image-gen": {
"command": "npx",
"args": ["together-mcp@latest -y"],
"env": {
"TOGETHER_API_KEY": "<API KEY>"
}
}
}
}
Before using the server, you'll need:
The server provides one tool: generate_image
The image generation tool accepts the following parameters:
{
// Required
prompt: string; // Text description of the image to generate
// Optional with defaults
model?: string; // Default: "black-forest-labs/FLUX.1-schnell-Free"
width?: number; // Default: 1024 (min: 128, max: 2048)
height?: number; // Default: 768 (min: 128, max: 2048)
steps?: number; // Default: 1 (min: 1, max: 100)
n?: number; // Default: 1 (max: 4)
response_format?: string; // Default: "b64_json" (options: ["b64_json", "url"])
image_path?: string; // Optional: Path to save the generated image as PNG
}
Here's a minimal request with just the required prompt:
{
"name": "generate_image",
"arguments": {
"prompt": "A serene mountain landscape at sunset"
}
}
You can override any defaults and specify a path to save the image:
{
"name": "generate_image",
"arguments": {
"prompt": "A serene mountain landscape at sunset",
"width": 1024,
"height": 768,
"steps": 20,
"n": 1,
"response_format": "b64_json",
"model": "black-forest-labs/FLUX.1-schnell-Free",
"image_path": "/path/to/save/image.png"
}
}
The response will be a JSON object containing:
{
"id": string, // Generation ID
"model": string, // Model used
"object": "list",
"data": [
{
"timings": {
"inference": number // Time taken for inference
},
"index": number, // Image index
"b64_json": string // Base64 encoded image data (if response_format is "b64_json")
// OR
"url": string // URL to generated image (if response_format is "url")
}
]
}
If you provided an image_path
and the save was successful, the response will include confirmation of the save location.
prompt
parameter is required; all others use defaults if not providedTo add this MCP server to Claude Code, run this command in your terminal:
claude mcp add-json "together-image-gen" '{"command":"npx","args":["together-mcp@latest -y"],"env":{"TOGETHER_API_KEY":"<API KEY>"}}'
See the official Claude Code MCP documentation for more details.
There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json
file so that it is available in all of your projects.
If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json
file.
To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".
When you click that button the ~/.cursor/mcp.json
file will be opened and you can add your server like this:
{
"mcpServers": {
"together-image-gen": {
"command": "npx",
"args": [
"together-mcp@latest -y"
],
"env": {
"TOGETHER_API_KEY": "<API KEY>"
}
}
}
}
To add an MCP server to a project you can create a new .cursor/mcp.json
file or add it to the existing one. This will look exactly the same as the global MCP server example above.
Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.
The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.
You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

"TOGETHER_API_KEY": "<API KEY>"
}
}
}
}
