Features

• High-quality image generation powered by the Flux.1 Schnell model

• Clear error handling for prompt validation and API issues
• Easy integration with MCP-compatible clients
• Optional image saving to disk in PNG format

Installation

npm install together-mcp

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": {
