# Image Generation MCP Server 

This MCP server provides image generation capabilities using the Replicate Flux model.

Setup

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

```json { “mcpServers”: { “image-gen”: { “command”: “node”, “args”: [“/path/to/image-gen-server/build/index.js”], “env”: { “REPLICATE_API_TOKEN”: “your-replicate-api-token”, “MODEL”: “alternative-model-name” }, “disabled”: false, “autoApprove”: [] } } } ```

2. Get your Replicate API token:
   • Sign up/login at https://replicate.com
   • Go to https://replicate.com/account/api-tokens
   • Create a new API token
   • Copy the token and replace `your-replicate-api-token` in the MCP settings
