Overview

What is Replicate Flux?

Replicate Flux is a Model Context Protocol (MCP) server that generates images using Replicate's black-forest-labs/flux-schnell model and stores them in Cloudflare R2. It is designed for developers who need an MCP‑compatible image generation tool that can be integrated into AI systems like Claude Desktop or Cursor.

How to use Replicate Flux?

Install manually or via Smithery, set required environment variables (REPLICATE_API_TOKEN, STORAGE_ENDPOINT, STORAGE_ACCESS_KEY, STORAGE_SECRET_KEY, STORAGE_BUCKET, STORAGE_DOMAIN), then run node index.js. The server exposes a generate-image tool that accepts a prompt (text) and filename (desired filename) and returns an accessible image URL.

FAQ from Replicate Flux

What are the prerequisites to run Replicate Flux?

Node.js v16 or higher, a Replicate API token, and a Cloudflare R2 bucket with credentials (endpoint, access key, secret key, bucket name, domain).

How do I configure environment variables?

Create a .env file with the following variables: REPLICATE_API_TOKEN, STORAGE_ENDPOINT, STORAGE_ACCESS_KEY, STORAGE_SECRET_KEY, STORAGE_BUCKET, and STORAGE_DOMAIN.

How can I test the server?

Run node test.js. The test script generates an image from a sample prompt, uploads it to R2, and prints the accessible URL.

What transports or authentication does Replicate Flux use?

The server communicates via MCP protocol over standard input/output. Authentication uses the Replicate API token for image generation and Cloudflare R2 credentials for storage.

What should I do if image generation or upload fails?

Check your Replicate API token and quota for generation issues. For R2 upload failures, verify your R2 credentials and bucket permissions. If generated images are inaccessible, ensure the bucket has proper CORS configuration.
