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
{
"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"
}
}
}
}
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"
}
}
}
}
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
-
pip
#首先安装依赖 $ pip install hh_mcp_comfyui $ python -m hh_mcp_comfyui
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:

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
-
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
-
重启服务自动加载新工作流
