Overview
What is Flux cf?
Flux cf is an MCP server that enables AI assistants to generate images using Black Forest Labs' Flux model via a Cloudflare Worker API. It is intended for developers integrating image generation into MCP-compatible clients like Cursor, Claude Desktop, Cline, or Zed.
How to use Flux cf?
Install and run directly with npx, setting the FLUX_API_TOKEN and FLUX_API_URL environment variables. Alternatively, clone the repository, install dependencies, and build from source. Configure the server in your MCP client (e.g., Cursor or Claude Desktop) using the command env FLUX_API_TOKEN=YOUR_TOKEN FLUX_API_URL=YOUR_API_URL npx -y flux-cloudflare-mcp.
Key features of Flux cf
- High-quality image generation via the Flux model
- Seamless integration with MCP-compatible AI assistants
- Customizable parameters: aspect ratio, inference steps
- Local processing through a Cloudflare Worker endpoint
- Chat completions available using the same API
Use cases of Flux cf
- Generate images directly from within an AI assistant like Claude
- Customize image output with prompts, steps, and aspect ratios
- Deploy a light‑weight image generation API on Cloudflare Workers
Frequently asked questions
How do I deploy the required Flux API?
You can deploy using snakeying/flux-api-worker (a simple Cloudflare Worker) or aigem/cf-flux-remix (a feature‑rich implementation with a web UI). Follow the instructions in each repository.
What parameters can I pass to `generate_image`?
The tool accepts a required `prompt`, an optional `num_inference_steps` (1‑4, default 4), and an optional `aspect_ratio` (e.g., "16:9", default "1:1").
Does the model have any safety filters?
Yes, the Flux model includes a built‑in safety filter that may block certain prompts.
What transports or authentication does the server use?
The server uses environment‑variable‑based authentication (`FLUX_API_TOKEN`) and connects to the Flux API over standard HTTPS. It is MCP‑compatible via the Model Context Protocol SDK.
