About Hh Mcp Comfyui

Hh Mcp Comfyui is an MCP server that generates images by calling workflows on a local ComfyUI instance through its API. It is aimed at users who want to create images from natural language prompts, and it can substitute prompts and sizes in workflows at runtime.

Key features

  1. 01Text-to-image and image-to-image tools over MCP
  2. 02Dynamic prompt and image size substitution in workflows
  3. 03Automatic loading of JSON workflows from a directory
  4. 04Support for a kontext image editing workflow

Use cases

  1. 01Generating images from natural language in Cherry Studio or Cline
  2. 02Editing images or removing backgrounds from reference images
  3. 03Exposing custom local ComfyUI workflows to AI clients

MCP support

This project is an MCP server that exposes local ComfyUI workflows as resources and tools to MCP clients.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

mcp.json · Universal config
{
"mcpServers": {
"hh-mcp-comfyui": {
"command": "uvx",
"args": [
"hh-mcp-comfyui"
]
}
}
}
Run commanduvx hh-mcp-comfyui

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

Packages
pypihh-mcp-comfyui

Tools

Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

安装依赖

1. 确保已安装Python 3.12+

2. 使用uv管理Python环境:

  • 安装uv:
    # On macOS and Linux.
    $ curl -LsSf https://astral.sh/uv/install.sh | sh
    
    # On Windows.
    $ powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
    
    # 更新uv(非必要操作):
    $ uv self update
    

测试运行服务

  • uvx方式
    $ uvx hh-mcp-comfyui
    
    INFO:hh_mcp_comfyui.server:Scanning for workflows in: C:\Users\tianw\AppData\Local\uv\cache\archive-v0\dp4MTo0f1qL0DdYF_BYCL\Lib\site-packages\hh_mcp_comfyui\workflows
    INFO:hh_mcp_comfyui.server:Starting ComfyUI MCP Server...
    
  • pip方式
    $ pip install hh_mcp_comfyui
    
    $ python -m hh_mcp_comfyui
    
    INFO:hh_mcp_comfyui.server:Scanning for workflows in: F:\Python\Python313\Lib\site-packages\hh_mcp_comfyui\workflows
    INFO:hh_mcp_comfyui.server:Starting ComfyUI MCP Server...
    

出现上面的信息表示服务启动成功

使用方法

必须确保本地ComfyUI实例正在运行(默认地址: http://127.0.0.1:8188) ComfyUI安装地址

Cherry Studio、Cline、Cursor等客户端的使用方式
uvx MCP服务配置
{
  "mcpServers": {
    "hh-mcp-comfyui": {
      "command": "uvx",
      "args": [
        "hh-mcp-comfyui@latest"
      ],
      "env": {
        "COMFYUI_API_BASE": "http://127.0.0.1:8188",
        "COMFYUI_WORKFLOWS_DIR": "/path/hh-mcp-comfyui/workflows"
      }
    }
  }
}
pip MCP服务配置

需要先执行命令窗口先执行:pip install hh_mcp_comfyui

{
  "mcpServers": {
    "hh-mcp-comfyui": {
      "command": "python",
      "args": [
        "-m",
        "hh_mcp_comfyui"
      ],
      "env": {
        "COMFYUI_API_BASE": "http://127.0.0.1:8188",
        "COMFYUI_WORKFLOWS_DIR": "/path/hh-mcp-comfyui/workflows"
      }
    }
  }
}
docker MCP服务配置

前提是已安装docker

{
  "mcpServers": {
    "hh-mcp-comfyui": {
      "command": "docker",
      "args": [
          "run",
          "--net=host",
          "-v",
          "/path/hh-mcp-comfyui/workflows:/app/workflows",
          "-i",
          "--rm",
          "zjf2671/hh-mcp-comfyui:latest"
      ],
      "env": {
        "COMFYUI_API_BASE": "http://127.0.0.1:8188"
      }
    }
  }
}

样例工作流copy到指定工作流目录:

(注意:使用下面uvx或pip方式找到你的安装工作流目录的位置把样例工作流添加进去,然后重启你的MCP服务)

  • uvx

    $ uvx hh-mcp-comfyui
    

    image-2-f89caf964efbccdad7b6fa2672d1cac0.png

  • pip

    #首先安装依赖
    $ pip install hh_mcp_comfyui
    $ python -m hh_mcp_comfyui
    

    image-3-03a069f40492fea9947a351b8707aa3f.png

测试

使用MCP Inspector测试服务端工具

  • uvx方式
    $ npx @modelcontextprotocol/inspector uvx hh-mcp-comfyui
    
  • pip方式
    $ pip install hh_mcp_comfyui
    $ npx @modelcontextprotocol/inspector python -m hh_mcp_comfyui
    
  • docker方式
    $ npx @modelcontextprotocol/inspector docker run --net=host -i --rm zjf2671/hh-mcp-comfyui
    

然后点击连接如图即可调试: image-1-44c6a003ee317093afe5a61cfe028720.png

使用注意事项(针对没有用过comfyui的特别注意)

  • 默认工作流为t2image_bizyair_flux
  • 图片尺寸默认为1024x1024
  • 服务启动时会自动加载workflows目录下的所有JSON工作流文件
  • 如果你使用的是本项目中的样例工作流需要在comfyui中下载个插件,详细操作请查看:样例工作流插件安装教程
  • 如果使用你本地的comfyui工作流的话,先要保证你的工作流能在comfyui正常运行,然后需要导出(API)的JSON格式,并放入到你本地的/path/hh_mcp_comfyui/workflows目录中

添加新工作流

  1. 将工作流JSON文件放入/path/hh_mcp_comfyui/workflows目录中

    如果是uvx和pip启动方式请看上面 《样例工作流copy到指定工作流目录》 的使用方式

  2. 重启服务自动加载新工作流

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
