Text tutorial: 3 steps to equip Claude with Desktop Commander and let him run the command to change the file himself图文教程：三步给 Claude 装上 Desktop Commander，让它自己跑命令改文件

The unblocked network executes npx @ wonderwhy-er/desktop-commander @ latest directly in the terminal, and npx will automatically download and run.

For users with network inconvenience, download the official npm installation package (tgz format 1.70 MB) accompanying this article, and remember the local path after decompression.

Verification: The command line executes npx @ wonderwhy-er/desktop-commander --help, and you can see the help information that the package is OK.

Claude Desktop: Open the developer configuration in the settings, edit claude_desktop_config.json, add the desktop-commander item in mcpServers, fill in npx with command, and fill in "@ wonderwhy-er/desktop-commander" with args (change the offline package to the local path).

Claude Code: Execute claude mcp add desktop-commander --npx @ wonderwhy-er/desktop-commander one command to complete the registration.

After saving and restarting the client, ask "What desktop-commander tools do you have now" in the conversation. You can list the terminals and file tools to access successfully.

Terminal capability: Let it "run npm run build in the project directory, post the error report and explain", observe its own execution command and read the output.

Search ability: Let it “find all files with dead API addresses in the project”, and it will use recursive search to give the file list and line number directly.

Code modification ability: Let it "fix the function that reported the error in diff mode". The modification given by it only moves the target line, does not rewrite the entire file, and allows it to rerun the verification after modification.

This plugin is very permissive (can execute arbitrary commands). It is recommended to enable it only in trusted projects. Important directories should be submitted to git before letting it work.

Long tasks use its process management features: let it start background processes, read output by line, instead of blocking waiting all the time.

I think it is easy to use. You can go to the GitHub repository to order a star. The author updates very often. Before locking the version number, look at changelog.
