Together AI Image Server

A TypeScript-based MCP (Model Context Protocol) server for generating images using Together AI API.

Overview

This server provides a simple interface to generate images using Together AI's image generation models through the MCP protocol. It allows Claude and other MCP-compatible assistants to generate images based on text prompts.

Features

Tools

generate_image - Generate images from text prompts
- Takes a text prompt as required parameter
- Optional parameters for controlling generation steps and number of images
- Returns URLs and local paths to generated images

Prerequisites

Node.js (v14 or later recommended)
Together AI API key

Installation

# Clone the repository
git clone https://github.com/zym9863/together-ai-image-server.git
cd together-ai-image-server

# Install dependencies
npm install

Configuration

Set your Together AI API key as an environment variable:

# On Linux/macOS
export TOGETHER_API_KEY="your-api-key-here"

# On Windows (Command Prompt)
set TOGETHER_API_KEY=your-api-key-here

# On Windows (PowerShell)
$env:TOGETHER_API_KEY="your-api-key-here"

Alternatively, you can create a .env file in the project root:

TOGETHER_API_KEY=your-api-key-here

Development

Build the server:

npm run build

For development with auto-rebuild:

npm run watch

Usage with Claude Desktop

To use with Claude Desktop, add the server config:

On macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
On Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "Together AI Image Server": {
      "command": "/path/to/together-ai-image-server/build/index.js"
    }
  }
}

Replace /path/to/together-ai-image-server with the actual path to your installation.

Debugging

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:

npm run inspector

The Inspector will provide a URL to access debugging tools in your browser.
