添加TOOL时提示RunningHub API key is not configured

[xiao-gy]

我现在使用本地ComfyUI作为生图工具，在添加高斯模糊的工作流的例子时出错，提示

}: RunningHub API key is not configured. Please set RUNNINGHUB_API_KEY in your environment.

我的配置文件如下：

你添加的mcp tool的runninghub的，所以需要添加RUNNINGHUB_API_KEY才能运行。

两个解决方案：

1. 继续走runninghub，那就购买runninghub会员，然后把key配置进去；
2. 本地ComfyUI运行，那就添加tool时，发符合标准的本地ComfyUI工作流的API格式文件；
