Overview
What is Flux Schnell MCP Server?
Flux Schnell MCP Server is a Model Context Protocol (MCP) server that generates images by calling the Flux Schnell model through the Replicate API. It is designed for developers using MCP-compatible environments (e.g., Claude Desktop) who need to create AI-generated images from text prompts.
How to use Flux Schnell MCP Server?
Clone the repository, install dependencies with npm install, and build the server with npm run build. Configure the server in your MCP client (e.g., Claude Desktop or VSCode Roo) by providing the absolute path to the built index file and setting the REPLICATE_API_TOKEN environment variable. Use the generate_image tool via MCP calls, passing a required prompt argument (text description).

Frequently asked questions
How do I get a Replicate API Token?
Visit the Replicate website, sign up or log in, go to the API Tokens page, and click “Create API token”. Copy the generated token (format: r8_xxxxxx).
How do I configure Flux Schnell MCP Server in Claude Desktop?
Open the Claude Desktop configuration file (`claude_desktop_config.json`), add a server entry with the command `node`, the path to the built index.js, and set the environment variable `REPLICATE_API_TOKEN` to your token.
What arguments does the `generate_image` tool accept?
It requires a single argument `prompt` (a string describing the image). For best results, include detailed descriptions of style, scene, and elements.
How does the server return results?
The server returns the full response from the Replicate API, which includes the generated image URLs and other metadata. The response is delivered through the MCP protocol.
