smithery badge

A TypeScript-based MCP server that implements a text-to-image generation tool using the Flux Schnell model. This server integrates with Cloudflare's Flux Schnell worker API to provide image generation capabilities through MCP.

Features

Tools

  • generate_image - Generate images from text descriptions
    • Takes a text prompt as input (1-2048 characters)
    • Returns the path to the generated image file

Environment Variables

The following environment variables must be configured:

  • FLUX_API_URL - The URL of the Flux Schnell API endpoint
  • FLUX_API_TOKEN - Your authentication token for the Flux Schnell API
  • WORKING_DIR (optional) - Directory where generated images will be saved (defaults to current working directory)

Development

Install dependencies:

npm install
# or
pnpm install

Build the server:

npm run build
# or
pnpm build

Installation

Installing via Smithery

To install Flux Schnell Image Generator for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @bytefer/mcp-flux-schnell --client claude

Cursor Configuration

There are two ways to configure the MCP server in Cursor:

Project Configuration

For tools specific to a project, create a .cursor/mcp.json file in your project directory:

{
  "mcpServers": {
    "mcp-flux-schnell": {
      "command": "node",
      "args": ["/path/to/mcp-flux-schnell/build/index.js"],
      "env": {
        "FLUX_API_URL": "your flux api url",
        "FLUX_API_TOKEN": "your flux api token",
        "WORKING_DIR": "your working directory"
      }
    }
  }
}

This configuration will only be available within the specific project.

Global Configuration

For tools that you want to use across all projects, create a ~/.cursor/mcp.json file in your home directory with the same configuration:

{
  "mcpServers": {
    "mcp-flux-schnell": {
      "command": "node",
      "args": ["/path/to/mcp-flux-schnell/build/index.js"],
      "env": {
        "FLUX_API_URL": "your flux api url",
        "FLUX_API_TOKEN": "your flux api token",
        "WORKING_DIR": "your working directory"
      }
    }
  }
}

This makes the MCP server available in all your Cursor workspaces.
