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

1. 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

• 🔍 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

File Preview UI & Markdown Editor

Desktop Commander includes a rich file preview widget in Claude Desktop that renders files visually as AI works with them.

Supported file types

• Markdown — rendered preview with a built-in editor
• Images — inline display (PNG, JPEG, GIF, WebP, etc.)
• Code files — syntax-highlighted source view
• HTML — rendered preview with toggle to source view
• Directories — interactive tree with expand/collapse and lazy loading
• PDF, Excel, DOCX — native content extraction and display

Markdown Editor

When viewing a .md file in Claude Desktop, you can edit it directly inside the preview panel — no need to open a separate app.

How to use:

1. Ask Claude to read or create a markdown file
2. Expand the file preview to fullscreen using the ⤢ Expand button
3. The editor activates automatically in fullscreen mode
4. Edit your content with a live preview toggle, copy, undo, and save controls
5. Changes are saved back to disk; collapse to return to inline view

Editor features:

• Live edit / preview toggle — switch between raw markdown and rendered output
• Auto-save to disk with save status indicator
• Undo support to revert unsaved changes
• Copy button to grab the full markdown source
• Open in editor — launch your default markdown app directly from the panel
• Partial-file awareness — loads and merges surrounding lines when the file was only partially read
• Text selection context — select text in preview mode and the AI can reference your selection

Directory Browser

When Claude runs list_directory, the result opens as an interactive file tree inside the preview panel — not just raw text output.

Features:

• Expandable tree — folders expand and collapse on click; top-level contents shown immediately
• Lazy loading — subfolders load on demand to keep the initial view fast
• Large directory handling — directories with many items show a ⚠ click to load all button instead of overwhelming the view
• Open in Finder/Explorer — each folder has a quick-open button to reveal it in your file manager
• Click to preview — clicking any file in the tree opens it in the file preview panel directly
• Back navigation — after opening a file from the tree, a ← Back button returns you to the directory view

Other preview features

• Expand / collapse — toggle between compact summary row and full panel
• Open in folder — reveal the file in Finder/Explorer with one click
• Load more lines — incrementally load content above or below a partial read window
• Text selection — highlight text in any preview; the AI can see and reference your selection

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

Local Tool History and Audit Logs

Desktop Commander keeps tool-call records locally on the machine running the MCP server. These local files are separate from optional telemetry and are not a server-side historical audit log.

claude_tool_call.log — local argument log

Every tool call handled by the local MCP server is appended as a text line containing an ISO timestamp, the tool name, and the JSON-serialized arguments. Arguments are not redacted or sanitized before being written to this local file, so it may contain command text, file paths, or other sensitive values passed to tools. Tool outputs are not written to this file.

The active file rotates when it reaches 10 MB. The previous file is renamed using a timestamp, for example claude_tool_call_2026-09-07_14-32-10.log, and a new claude_tool_call.log is created. Rotated files are not automatically deleted by the logger.
