Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

[!CAUTION] PROJECT DEPRECATED - No longer maintained. Use https://github.com/wonderwhy-er/DesktopCommanderMCP instead for similar functionality.

MCP server for secure command-line interactions on Windows systems, enabling controlled access to PowerShell, CMD, Git Bash shells, and remote systems via SSH. It allows MCP clients (like Claude Desktop) to perform operations on your system, similar to Open Interpreter.

[!IMPORTANT] This MCP server provides direct access to your system's command line interface and remote systems via SSH. When enabled, it grants access to your files, environment variables, command execution capabilities, and remote server management. - Review and restrict allowed paths and SSH connections - Enable directory restrictions - Configure command blocks - Consider security implications See Configuration for more details.

Questions

What is the Windows CLI MCP server?

Model Context Protocol server for secure command-line interactions on Windows systems

What tools does Windows CLI expose?

9 in total: 4 read-only, 4 that write, and 1 that can delete or overwrite (delete_ssh_connection). Every one is listed on this page with its risk.

Is Windows CLI safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B. Separately from the audit: 1 of its tools can destroy data, so scope the token you give it to what you actually need.

What credentials does Windows CLI need?

No credential environment variables were found in its source, so it appears to need none.

How does Windows CLI run?

It speaks stdio, so it runs as a local process your client starts. It is published on npm as @simonb97/server-win-cli at 0.2.1.

How current is this page?

The grade is for one exact copy of the source (59df4ad4e79b), read on 2026-10-06. The repository is watched and re-audited when it changes.
