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

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

FAQ from Flux cf

What does Flux cf need to run?

It requires a deployed Flux API endpoint (from snakeying/flux-api-worker or aigem/cf-flux-remix) and the corresponding FLUX_API_TOKEN and FLUX_API_URL environment variables.

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.
