Hello, can you provide this MCP service?

这个我也碰到了：如果在离线条件下，使用docker部署MCP，可能会触发FastMCP或者MCP组件的某个BUG。看定位是session.py:363。

另外使用MCP这个组件会报这个错误，但是如果在大模型对话组件里配置这个MCP，反而不会报错，就很神奇。

I also encountered this: if you use docker to deploy MCP under offline conditions, it may trigger a bug in FastMCP or MCP component. The positioning is session.py:363.

In addition, using the MCP component will report this error, but if you configure this MCP in the big model dialogue component, there will be no error, which is amazing.
