Installation

Or run directly:

npx together-mcp@latest

Configuration

Add to your MCP server configuration:

{ "mcpServers": { "together-image-gen": { "command": "npx", "args": ["together-mcp@latest -y"], "env": { "TOGETHER_API_KEY": "<API KEY>" } } } }

Usage

The server provides one tool: generate_image

Using generate_image

This tool has only one required parameter - the prompt. All other parameters are optional and use sensible defaults if not provided.

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 }

Minimal Request Example

Only the prompt is required:

{ "name": "generate_image", "arguments": { "prompt": "A serene mountain landscape at sunset" } }

Full Request Example with Image Saving

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" } }

Response Format

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 image_path was provided and the save was successful, the response will include confirmation of the save location.

Default Values

If not specified in the request, these defaults are used:

model: "black-forest-labs/FLUX.1-schnell-Free"
width: 1024
height: 768
steps: 1
n: 1
response_format: "b64_json"

Important Notes

Only the prompt parameter is required
All optional parameters use defaults if not provided
When provided, parameters must meet their constraints (e.g., width/height ranges)
Base64 responses can be large - use URL format for larger images
When saving images, ensure the specified directory exists and is writable
