Overview
I became interested in MCP servers, so I looked into it.
I asked the AI.
I tried the sample.
I tried Desktop-Commander.
I tried compiling C#.
Add mcpServers to claude_desktop_config.json.
An error occurred.
Install desktop-commander using npx
An error occurred

Steps to create hello.cs using Desktop Commander and compile and run it with csc.
Is Desktop Commander unusable?
I’ll check whether it can be used.
It has loaded, so I’ll retrieve the configuration to check whether it actually works.
Yes, it can be used. My previous response was insufficient. Since Desktop Commander is connected, it can operate your own Windows PC. I just retrieved the configuration and confirmed the connection.
Confirmed environment
- OS: Windows (default shell: PowerShell)
- Node.js: Available (v26.13.0)
- Python: Not detected (may not be installed or may not be included in the PATH)
What you can do with Desktop Commander
- Execute commands on your PC (such as PowerShell)
- Read, write, and edit files (text, Excel, PDF, DOCX, etc.)
- List folders; list and terminate processes
Precautions
- Unlike my sandbox earlier, this affects files and processes on the actual PC. Highly consequential operations such as deletion and overwriting will be explained before they are executed.
-
Dangerous commands such as sudo, format, and shutdown are blocked.
Tell me what you want to execute. For example, you can ask me to “list the files in this folder” or “run this script.”
The working folder is C:\Users\ohisa\claude, and will be used
Understood. I’ll check whether the folder exists and create it if it does not.
C:\Users\ohisa\claude already exists and is empty. It will be used for all future file creation and command execution.
Note that each command runs in a separate process, so the effect of Set-Location does not carry over to the next command. Therefore, either change to this folder each time or specify an absolute path.
What would you like to do next? For example, I can test the behavior by creating hello.cs and compiling and running it with csc.
Create hello.cs, then compile and run it with csc
Created hello.cs, compiled it with csc, and ran it successfully.
The output was as follows.
Hello, World!
Hello, world!
The following two items have been created in C:\Users\ohisa\claude.
-
hello.cs: Source code
-
hello.exe: Compiled executable file
The compiler used was the 64-bit version of .NET Framework 4 (Framework64\v4.0.30319\csc.exe). Japanese characters were also displayed correctly.
You can also create another program, such as one that accepts arguments or reads and writes files.
Photo
hello.cs
using System;
class Hello
{
static void Main()
{Console.WriteLine("Hello, World!");
Console.WriteLine("Hello, World!");
}
}
That's all.
