Pitfalls of running an npx-based MCP server on Windows

I've been seriously trying to use MCP server for the past 2 days. Today, I successfully completed a small demo task using the coding agent plugin - Roo Code on VS Code. Here are some specific steps and pitfalls you're likely to encounter.

I added 2 MCP Servers in Roo Code, namely:

Initially, the "Filesystem" MCP server wouldn't run because I was using VS Code in Windows with PowerShell. If you're also a Windows user, you'll likely encounter errors running Node.js-based MCP servers. You can refer to the following two posts to resolve the issue:

Running a public server from WSL 2

Forward from: https://www.williamjbowman.com/blog/2020/04/25/running-a-public-server-from-wsl-2/

This week, for ReAsOnS, I wanted to run a server on WSL 2 that was accessible from the internet. This was surprisingly involved and requires lots of hard-to-find tricks to forward ports through 4 different layers of network abstractions and firewalls.

In WSL, make sure your server is using IPv4. I spent a hell of a long time just trying to figure out why I couldn’t access the server from localhost. I had successfully run a handful of local http servers from WSL that were accessible from the Windows host, so I wasn’t sure what the problem was. It turns out this server, written in Java, wouldn’t work until I added -Djava.net.preferIPv4Stack=true to the java options. It appears that Java was defaulting to IPv6, and WSL doesn’t forward IPv6 properly, or something.

发现了一个来自LinkedIn的关于SRE的非常好的教程👇: https://linkedin.github.io/school-of-sre/level101/systems_design/intro/ 其中它提到了Google的SRE教程(这个才是体系化的SRE)👇: https://sre.google/workbook/non-abstract-design/

通过搜索以及向New Bing提问，解除了我的一些疑惑:

需求分析是软件生命周期中的一个阶段。软件生命周期包括: 需求分析、架构设计、详细设计、编码、测试、部署和维护。
"UML建模"可以在需求分析、架构设计和详细设计阶段使用，用于描述软件系统的静态和动态特征。
在详细设计阶段之后，应该就产出了与具体代码密切相关的产物，比如类图、序列图、活动图等文档。

Create additional Ubuntu instance of WSL2

Obtain a tar file for the distribution

Prerequisite:

You must have WSL enabled with a Linux distribution installed running WSL 2.
You must have Docker Desktop for Windows installed with the WSL 2 engine enabled and integration checked See the Docker Desktop license agreement for updates on the terms of use.

Run below command in your current WSL Linux distro has enabled integration with Docker:

	#!/usr/bin/env python3

	import os
	import paramiko
	import argparse


	def main():
	parser = argparse.ArgumentParser()
	parser.add_argument(

	git clone https://github.com/pyenv/pyenv.git ~/.pyenv
	cd ~/.pyenv && src/configure && make -C src

	echo -e 'if shopt -q login_shell; then' \
	'\n export PYENV_ROOT="$HOME/.pyenv"' \
	'\n export PATH="$PYENV_ROOT/bin:$PATH"' \
	'\n eval "$(pyenv init --path)"' \
	'\nfi' >> ~/.bashrc
	echo -e 'if [ -z "$BASH_VERSION" ]; then'\
	'\n export PYENV_ROOT="$HOME/.pyenv"'\
