MCP Flux Studio

A powerful Model Context Protocol (MCP) server that brings Flux’s advanced image generation capabilities to your AI coding assistants. This server enables direct integration of Flux’s image generation, manipulation, and control features into Cursor and Windsurf (Codeium) IDEs.

Overview

MCP Flux Studio bridges the gap between AI coding assistants and Flux’s powerful image generation API, allowing seamless integration of image generation capabilities directly into your development workflow.

Features

• Image Generation

  • Text-to-image generation with precise control
  • Multiple model support (flux.1.1-pro, flux.1-pro, flux.1-dev, flux.1.1-ultra)
  • Customizable aspect ratios and dimensions

• Image Manipulation

  • Image-to-image transformation
  • Inpainting with customizable masks
  • Resolution upscaling and enhancement

• Advanced Controls

  • Edge-based generation (canny)
  • Depth-aware generation
  • Pose-guided generation

• IDE Integration

  • Full support for Cursor (v0.45.7+)
  • Compatible with Windsurf/Codeium Cascade (Wave 3+)
  • Seamless tool invocation through AI assistants

IDE Integration

Cursor (v0.45.7+)

MCP Flux Studio integrates seamlessly with Cursor’s AI assistant:

1. Configuration

   • Configure via Settings > Features > MCP
   • Supports both stdio and SSE connections
   • Environment variables can be set via wrapper scripts

2. Usage

   • Tools automatically available to Cursor’s AI assistant
   • Tool invocations require user approval
   • Real-time feedback on generation progress

Windsurf/Codeium (Wave 3+)

Integration with Windsurf’s Cascade AI:

1. Configuration

   • Edit ~/.codeium/windsurf/mcp_config.json
   • Supports process-based tool execution
   • Environment variables configured in JSON

2. Usage

   • Access tools through Cascade’s MCP toolbar
   • Automatic tool discovery and loading
   • Integrated with Cascade’s AI capabilities

For detailed IDE-specific setup instructions, see the Installation Guide.

Usage

The server provides the following tools:

generate

Generate an image from a text prompt.

{
  "prompt": "A photorealistic cat",
  "model": "flux.1.1-pro",
  "aspect_ratio": "1:1",
  "output": "generated.jpg"
}

img2img

Generate an image using another image as reference.

{
  "image": "input.jpg",
  "prompt": "Convert to oil painting",
  "model": "flux.1.1-pro",
  "strength": 0.85,
  "output": "output.jpg",
  "name": "oil_painting"
}

inpaint

Inpaint an image using a mask.

{
  "image": "input.jpg",
  "prompt": "Add flowers",
  "mask_shape": "circle",
  "position": "center",
  "output": "inpainted.jpg"
}

control

Generate an image using structural control.

{
  "type": "canny",
  "image": "control.jpg",
  "prompt": "A realistic photo",
  "output": "controlled.jpg"
}
