Uninstalling Desktop Commander

🤖 Automatic Uninstallation (Recommended)

The easiest way to completely remove Desktop Commander:

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

This automatic uninstaller will:

• ✅ Remove Desktop Commander from Claude's MCP server configuration
• ✅ Create a backup of your Claude config before making changes
• ✅ Provide guidance for complete package removal
• ✅ Restore from backup if anything goes wrong

🔧 Manual Uninstallation

If the automatic uninstaller doesn't work or you prefer manual removal:

Remove from Claude Configuration

1. Locate your Claude Desktop config file:

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

2. Edit the config file:

• Open the file in a text editor
• Find and remove the "desktop-commander" entry from the "mcpServers" section
• Save the file

Example - Remove this section:

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

Close and restart Claude Desktop to complete the removal.

🆘 Troubleshooting

If automatic uninstallation fails:

• Use manual uninstallation as a fallback

If Claude won't start after uninstalling:

• Restore the backup config file created by the uninstaller
• Or manually fix the JSON syntax in your claude_desktop_config.json

Getting Started

Once Desktop Commander is installed and Claude Desktop is restarted, you're ready to supercharge your Claude experience!

🚀 New User Onboarding

Desktop Commander includes intelligent onboarding to help you discover what's possible:

For New Users: When you're just getting started (fewer than 10 successful commands), Claude will automatically offer helpful getting-started guidance and practical tutorials after you use Desktop Commander successfully.

Request Help Anytime: You can ask for onboarding assistance at any time by simply saying:

• "Help me get started with Desktop Commander"
• "Show me Desktop Commander examples"
• "What can I do with Desktop Commander?"

Claude will then show you beginner-friendly tutorials and examples, including:

• 📁 Organizing your Downloads folder automatically
• 📊 Analyzing CSV/Excel files with Python
• ⚙️ Setting up GitHub Actions CI/CD
• 🔍 Exploring and understanding codebases
• 🤖 Running interactive development environments

Usage

The server provides a comprehensive set of tools organized into several categories:

Available Tools

Quick Examples

Data Analysis:

"Analyze sales.csv and show top customers" → Claude runs Python code in memory

Remote Access:

"SSH to my server and check disk space" → Claude maintains SSH session

Development:

"Start Node.js and test this API" → Claude runs interactive Node session

Tool Usage Examples

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

Enhanced Edit Block Features

The edit_block tool includes several enhancements for better reliability:

1. Improved Prompting: Tool descriptions now emphasize making multiple small, focused edits rather than one large change
2. Fuzzy Search Fallback: When exact matches fail, it performs fuzzy search and provides detailed feedback
3. Character-level Diffs: Shows exactly what's different using {-removed-}{+added+} format
4. Multiple Occurrence Support: Can replace multiple instances with expected_replacements parameter
5. Comprehensive Logging: All fuzzy searches are logged for analysis and debugging

When a search fails, you'll see detailed information about the closest match found, including similarity percentage, execution time, and character differences. All these details are automatically logged for later analysis using the fuzzy search log tools.

Docker Support

🐳 Isolated Environment Usage

Desktop Commander can be run in Docker containers for complete isolation from your host system, providing zero risk to your computer. This is perfect for testing, development, or when you want complete sandboxing.

Installation Instructions

1. Install Docker for Windows/Mac

   • Download and install Docker Desktop from docker.com

2. Get Desktop Commander Docker Configuration

   • Visit: https://hub.docker.com/mcp/server/desktop-commander/manual
   • Option A: Use the provided terminal command for automated setup
   • Option B: Click "Standalone" to get the config JSON and add it manually to your Claude Desktop config

3. Mount Your Machine Folders (Coming Soon)

   • Instructions on how to mount your local directories into the Docker container will be provided soon
   • This will allow you to work with your files while maintaining complete isolation

Benefits of Docker Usage

• Complete isolation from your host system
• Consistent environment across different machines
• Easy cleanup - just remove the container when done
• Perfect for testing new features or configurations

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

Fuzzy Search Log Analysis (npm scripts)

The fuzzy search logging system includes convenient npm scripts for analyzing logs outside of the MCP environment:

# View recent fuzzy search logs
npm run logs:view -- --count 20

# Analyze patterns and performance
npm run logs:analyze -- --threshold 0.8

# Export logs to CSV or JSON
npm run logs:export -- --format json --output analysis.json

# Clear all logs (with confirmation)
npm run logs:clear

For detailed documentation on these scripts, see scripts/README.md.

Fuzzy Search Logs

Desktop Commander includes comprehensive logging for fuzzy search operations in the edit_block tool. When an exact match isn't found, the system performs a fuzzy search and logs detailed information for analysis.

What Gets Logged

Every fuzzy search operation logs:

• Search and found text: The text you're looking for vs. what was found
• Similarity score: How close the match is (0-100%)
• Execution time: How long the search took
• Character differences: Detailed diff showing exactly what's different
• File metadata: Extension, search/found text lengths
• Character codes: Specific character codes causing differences

Log Location

Logs are automatically saved to:

• macOS/Linux: ~/.claude-server-commander-logs/fuzzy-search.log
• Windows: %USERPROFILE%\.claude-server-commander-logs\fuzzy-search.log

What You'll Learn

The fuzzy search logs help you understand:

1. Why exact matches fail: Common issues like whitespace differences, line endings, or character encoding
2. Performance patterns: How search complexity affects execution time
3. File type issues: Which file extensions commonly have matching problems
4. Character encoding problems: Specific character codes that cause diffs

Audit Logging

Desktop Commander now includes comprehensive logging for all tool calls:

What Gets Logged

• Every tool call is logged with timestamp, tool name, and arguments (sanitized for privacy)
• Logs are rotated automatically when they reach 10MB in size

Log Location

Logs are saved to:

• macOS/Linux: ~/.claude-server-commander/claude_tool_call.log
• Windows: %USERPROFILE%\.claude-server-commander\claude_tool_call.log

This audit trail helps with debugging, security monitoring, and understanding how Claude is interacting with your system.

Handling Long-Running Commands

For commands that may take a while:

Configuration Management

⚠️ Important Security Warnings

For comprehensive security information and vulnerability reporting: See SECURITY.md

1. Known security limitations: Directory restrictions and command blocking can be bypassed through various methods including symlinks, command substitution, and absolute paths or code execution

2. Always change configuration in a separate chat window from where you're doing your actual work. Claude may sometimes attempt to modify configuration settings (like allowedDirectories) if it encounters filesystem access restrictions.

3. The allowedDirectories setting currently only restricts filesystem operations, not terminal commands. Terminal commands can still access files outside allowed directories.

4. For production security: Use the Docker installation which provides complete isolation from your host system.

Configuration Tools

You can manage server configuration using the provided tools:

// Get the entire config
get_config({})

// Set a specific config value
set_config_value({ "key": "defaultShell", "value": "/bin/zsh" })

// Set multiple config values using separate calls
set_config_value({ "key": "defaultShell", "value": "/bin/bash" })
set_config_value({ "key": "allowedDirectories", "value": ["/Users/username/projects"] })

The configuration is saved to config.json in the server's working directory and persists between server restarts.

Understanding fileWriteLineLimit

The fileWriteLineLimit setting controls how many lines can be written in a single write_file operation (default: 50 lines). This limit exists for several important reasons:

Why the limit exists:

• AIs are wasteful with tokens: Instead of doing two small edits in a file, AIs may decide to rewrite the whole thing. We're trying to force AIs to do things in smaller changes as it saves time and tokens
• Claude UX message limits: There are limits within one message and hitting "Continue" does not really work. What we're trying here is to make AI work in smaller chunks so when you hit that limit, multiple chunks have succeeded and that work is not lost - it just needs to restart from the last chunk

Setting the limit:

// You can set it to thousands if you want
set_config_value({ "key": "fileWriteLineLimit", "value": 1000 })

// Or keep it smaller to force more efficient behavior
set_config_value({ "key": "fileWriteLineLimit", "value": 25 })

Maximum value: You can set it to thousands if you want - there's no technical restriction.

Best practices:

• Keep the default (50) to encourage efficient AI behavior and avoid token waste
• The system automatically suggests chunking when limits are exceeded
• Smaller chunks mean less work lost when Claude hits message limits

Best Practices

1. Create a dedicated chat for configuration changes: Make all your config changes in one chat, then start a new chat for your actual work.

2. Be careful with empty allowedDirectories: Setting this to an empty array ([]) grants access to your entire filesystem for file operations.

3. Use specific paths: Instead of using broad paths like /, specify exact directories you want to access.

4. Always verify configuration after changes: Use get_config({}) to confirm your changes were applied correctly.

Command Line Options

Desktop Commander supports several command line options for customizing behavior:

Disable Onboarding

By default, Desktop Commander shows helpful onboarding prompts to new users (those with fewer than 10 tool calls). You can disable this behavior:

# Disable onboarding for this session
node dist/index.js --no-onboarding

# Or if using npm scripts
npm run start:no-onboarding

# For npx installations, modify your claude_desktop_config.json:
{
  "mcpServers": {
    "desktop-commander": {
      "command": "npx",
      "args": [
        "-y",
        "@wonderwhy-er/desktop-commander@latest",
        "--no-onboarding"
      ]
    }
  }
}

When onboarding is automatically disabled:

• When the MCP client name is set to "desktop-commander"
• When using the --no-onboarding flag
• After users have used onboarding prompts or made 10+ tool calls

Debug information: The server will log when onboarding is disabled: "Onboarding disabled via --no-onboarding flag"

Using Different Shells

You can specify which shell to use for command execution:

// Using default shell (bash or system default)
execute_command({ "command": "echo $SHELL" })

// Using zsh specifically
execute_command({ "command": "echo $SHELL", "shell": "/bin/zsh" })

// Using bash specifically
execute_command({ "command": "echo $SHELL", "shell": "/bin/bash" })

This allows you to use shell-specific features or maintain consistent environments across commands.

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

Model Context Protocol Integration

This project extends the MCP Filesystem Server to enable:

• Local server support in Claude Desktop
