Quick Start

**1. Install ComfyUI** (if you haven't already): [ComfyUI Desktop](https://www.comfy.org/download) or [from source](https://github.com/comfyanonymous/ComfyUI)

**2. Add the MCP server** to your Claude Code config (`~/.claude/settings.json`):

{
  "mcpServers": {
    "comfyui": {
      "command": "npx",
      "args": ["-y", "comfyui-mcp"],
      "env": {
        "CIVITAI_API_TOKEN": ""
      }
    }
  }
}

**3. Start using it.** With ComfyUI running, ask Claude to generate an image:

> Generate an image of a sunset over mountains

Claude will find (or download) a checkpoint, build a workflow, execute it, and return the image.

**Note**: This runs as a standalone MCP server — no need to clone this repo. `npx` will download and run it automatically.
