Installation

First, ensure you've downloaded and installed the Claude Desktop app and you have npm installed.

Option 1: Install through npx

Just run this in terminal

npx @wonderwhy-er/desktop-commander@latest setup

For debugging mode (allows Node.js inspector connection):

npx @wonderwhy-er/desktop-commander@latest setup --debug

Restart Claude if running

Option 2: Using bash script installer (macOS)

For macOS users, you can use our automated bash installer which will check your Node.js version, install it if needed, and automatically configure Desktop Commander:

curl -fsSL https://raw.githubusercontent.com/wonderwhy-er/DesktopCommanderMCP/refs/heads/main/install.sh | bash

This script handles all dependencies and configuration automatically for a seamless setup experience.

Option 3: Installing via Smithery

To install Desktop Commander for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @wonderwhy-er/desktop-commander --client claude

Option 4: Add to claude_desktop_config by hand

Add this entry to your claude_desktop_config.json:

• On Mac: ~/Library/Application\ Support/Claude/claude_desktop_config.json
• On Windows: %APPDATA%\Claude\claude_desktop_config.json
• On Linux: ~/.config/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "desktop-commander": {
      "command": "npx",
      "args": [
        "-y",
        "@wonderwhy-er/desktop-commander"
      ]
    }
  }
}

Restart Claude if running

Option 5: Checkout locally

1. Clone and build:

git clone https://github.com/wonderwhy-er/ClaudeComputerCommander.git
cd ClaudeComputerCommander
npm run setup

Restart Claude if running

The setup command will:

• Install dependencies
• Build the server
• Configure Claude's desktop app
• Add MCP servers to Claude's config if needed

Updating Desktop Commander

When installed through npx (Option 1) or Smithery (Option 2), Desktop Commander will automatically update to the latest version whenever you restart Claude. No manual update process is needed.

For manual installations, you can update by running the setup command again.

Usage

The server provides these tool categories:

Terminal Tools

• execute_command: Run commands with configurable timeout
• read_output: Get output from long-running commands
• force_terminate: Stop running command sessions
• list_sessions: View active command sessions
• list_processes: View system processes
• kill_process: Terminate processes by PID
• block_command/unblock_command: Manage command blacklist

Filesystem Tools

• read_file/write_file: Read files from local filesystem or URLs (supports viewing PNG, JPEG, GIF, and WebP images directly in Claude)
• create_directory/list_directory: Directory management
• move_file: Move/rename files
• search_files: Pattern-based file search
• get_file_info: File metadata
• search_code: Recursive ripgrep based text and code search

Edit Tools

• edit_block: Apply surgical text replacements (best for changes <20% of file size)
• write_file: Complete file rewrites (best for large changes >20% or when edit_block fails)

Search/Replace Block Format:

filepath.ext
<<<<<<< SEARCH
content to find
=======
new content
>>>>>>> REPLACE

Example:

src/main.js
<<<<<<< SEARCH
console.log("old message");
=======
console.log("new message");
>>>>>>> REPLACE

URL Support

• read_file can now fetch content from both local files and URLs
• Example: read_file with isUrl: true parameter to read from web resources
• Handles both text and image content from remote sources
• Images (local or from URLs) are displayed visually in Claude's interface, not as text
• Claude can see and analyze the actual image content
• Default 30-second timeout for URL requests

Handling Long-Running Commands

For commands that may take a while:

1. execute_command returns after timeout with initial output
2. Command continues in background
3. Use read_output with PID to get new output
4. Use force_terminate to stop if needed

Debugging

If you need to debug the server, you can install it in debug mode:

# Using npx
npx @wonderwhy-er/desktop-commander@latest setup --debug

# Or if installed locally
npm run setup:debug

This will:

1. Configure Claude to use a separate "desktop-commander" server
2. Enable Node.js inspector protocol with --inspect-brk=9229 flag
3. Pause execution at the start until a debugger connects
4. Enable additional debugging environment variables

To connect a debugger:

• In Chrome, visit chrome://inspect and look for the Node.js instance
• In VS Code, use the "Attach to Node Process" debug configuration
• Other IDEs/tools may have similar "attach" options for Node.js debugging

Important debugging notes:

• The server will pause on startup until a debugger connects (due to the --inspect-brk flag)
• If you don't see activity during debugging, ensure you're connected to the correct Node.js process
• Multiple Node processes may be running; connect to the one on port 9229
• The debug server is identified as "desktop-commander-debug" in Claude's MCP server list

Troubleshooting:

• If Claude times out while trying to use the debug server, your debugger might not be properly connected
• When properly connected, the process will continue execution after hitting the first breakpoint
• You can add additional breakpoints in your IDE once connected

Frequently Asked Questions

Here are answers to some common questions. For a more comprehensive FAQ, see our detailed FAQ document.

What is Claude Desktop Commander?

It's an MCP tool that enables Claude Desktop to access your file system and terminal, turning Claude into a versatile assistant for coding, automation, codebase exploration, and more.

How is this different from Cursor/Windsurf?

Unlike IDE-focused tools, Claude Desktop Commander provides a solution-centric approach that works with your entire OS, not just within a coding environment. Claude reads files in full rather than chunking them, can work across multiple projects simultaneously, and executes changes in one go rather than requiring constant review.

Do I need to pay for API credits?

No. This tool works with Claude Desktop's standard Pro subscription ($20/month), not with API calls, so you won't incur additional costs beyond the subscription fee.

Does Desktop Commander automatically update?

Yes, when installed through npx or Smithery, Desktop Commander automatically updates to the latest version when you restart Claude. No manual update process is needed.

What are the most common use cases?

• Exploring and understanding complex codebases
• Generating diagrams and documentation
• Automating tasks across your system
• Working with multiple projects simultaneously
• Making surgical code changes with precise control

Data Collection

During installation and setup, Desktop Commander collects anonymous usage data to help improve the tool. This includes:

• Operating system information
• Node.js and NPM versions
• Installation method and shell environment
• Error messages (if any occur during setup)

This data is collected using PostHog analytics and is associated with a machine-generated unique ID. No personal information is collected. This helps us understand how the tool is being used and identify common issues.

We are currently working on adding a built-in opt-out option for this data collection in an upcoming release. For now, if you wish to opt out, you can block network connections to eu.i.posthog.com in your firewall settings.
