Overview

AI-generated overview

Lets an assistant look up Flux-2 Online image-generation styles, pricing, FAQ and official links through read-only tools and resources.

What you can do
Exposes the Flux-2 Online knowledge surface to MCP clients. Tools include list_styles, which returns the site's image-generation styles and presets, get_pricing, which returns the canonical pricing entry point, and get_official_links, which returns official website, support and docs links. It also publishes resources for styles, pricing, FAQ and links, plus prompts that summarize the site and recommend a starting style. All output is text/markdown and read-only.
When to use it
Useful when someone asks an assistant about Flux-2 Online, its image-generation styles, model tiers, pricing or official links, or wants a starting style recommendation for a stated goal. It is a reference and discovery helper, not a tool for actually generating or editing images.
Requirements
Runs as a local stdio process on the user's machine (desktop clients only). Installation is via the Smithery CLI or from source with git, pnpm and Node.js, then an entry in the MCP client config pointing at src/index.mjs. No API keys, accounts, environment variables or headers are declared.
Before you install
Read-only and declared with no API keys, environment variables or headers (R4). It does not generate images itself; it only returns reference text about the Flux-2 Online service, so treat its pricing and style output as informational rather than authoritative. The README includes install commands and links to a third-party site; verify them yourself before running anything.

Installation

In SourceWeft

  1. Open Flux-2 Online MCP in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

🎨 About Flux-2 Online

Flux-2 Online is a web-based AI image and video generation platform built around the Flux family of models. Users describe what they want in a text prompt, choose a model suited to their needs — from the fast and budget-friendly Flux 2 Dev to the higher-fidelity Flux 2 Pro or the flexible Flux 2 Flex — and receive generated images within seconds. Beyond text-to-image, the platform bundles a set of editing tools: image-to-image transformation, face swap, background removal, image enhancement, and image-to-video conversion, all accessible from a single browser-based interface with no local installation required.

Key Features

  • Multiple Flux model tiers — Flux 2 Dev for speed, Flux 2 Pro for quality, Flux 2 Flex for granular control, plus additional models like Seedream and Qwen for complex text rendering.
  • LoRA styles library — A curated collection of artistic styles spanning anime, photorealism, and more, selectable at generation time to steer the visual aesthetic without prompt engineering alone.
  • Kontext consistency mode — Keeps character appearance and object details coherent across a sequence of generated images, useful for multi-panel or narrative work.
  • Bundled editing tools — Face swap, hairstyle modifier, text remover, background changer, professional photo generator, and product photography generator are included alongside the core image generator.
  • Image-to-video conversion — Powered by Seedance 1.0 Lite, the platform converts still images into short video clips with configurable duration and resolution settings.
  • API access — A RESTful API with webhook support lets developers integrate image generation into their own applications using Python, JavaScript, or any HTTP client.
  • Free tier with daily credits — Basic generation is available without a subscription; a credit-based system scales up to commercial-grade output, higher resolutions, and batch processing.

Use Cases

  • Content creation — Social media managers and bloggers generate on-brand illustrations or photography-style images from text prompts, bypassing stock photo licensing.
  • E-commerce product visuals — Store owners use the product photography generator and background tools to produce clean, professional product shots without a physical studio.
  • Concept iteration — Designers test visual directions quickly by generating multiple style variants in parallel before committing to a final look.
  • Short-form video assets — Marketers convert finished images into brief animated clips suitable for social ads, reels, or presentation slides.
  • Developer integration — Independent developers embed the API into creative apps, chatbots, or internal tools that need on-demand image generation without managing their own model infrastructure.

Who Is It For

Flux-2 Online targets a broad range of creators and builders who need AI-generated visuals without the overhead of running models locally. Graphic designers and marketing professionals will find the multi-model selector and LoRA library useful for iterating on visual styles quickly. E-commerce operators benefit from the dedicated product photography and background editing tools. Developers who want image generation as a service rather than a self-hosted pipeline can connect via the RESTful API. The free daily credit allowance also makes the platform accessible to individual hobbyists and students who want to explore AI image generation before committing to a paid plan.
