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:

Ask Claude to read or create a markdown file
Expand the file preview to fullscreen using the ⤢ Expand button
The editor activates automatically in fullscreen mode
Edit your content with a live preview toggle, copy, undo, and save controls
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:

hljs language-bash

# 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:

Why exact matches fail: Common issues like whitespace differences, line endings, or character encoding
Performance patterns: How search complexity affects execution time
File type issues: Which file extensions commonly have matching problems
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

Known security limitations: Directory restrictions and command blocking can be bypassed through various methods including symlinks, command substitution, and absolute paths or code execution
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.
The allowedDirectories setting currently only restricts filesystem operations, not terminal commands. Terminal commands can still access files outside allowed directories.
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:

hljs language-javascript

// 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:

hljs language-javascript

// 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

Create a dedicated chat for configuration changes: Make all your config changes in one chat, then start a new chat for your actual work.
Be careful with empty allowedDirectories: Setting this to an empty array ([]) grants access to your entire filesystem for file operations.
Use specific paths: Instead of using broad paths like /, specify exact directories you want to access.
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:

hljs language-bash

# 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:

hljs language-javascript

// 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.

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

Debugging

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

hljs language-bash

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

# Or if installed locally
npm run setup:debug

This will:

Configure Claude to use a separate "desktop-commander" server
Enable Node.js inspector protocol with --inspect-brk=9229 flag
Pause execution at the start until a debugger connects
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

Testimonials

It's a life saver! I paid Claude + Cursor currently which I always feel it's kind of duplicated. This solves the problem ultimately. I am so happy. Thanks so much. Plus today Claude has added the web search support. With this MCP + Internet search, it writes the code with the latest updates. It's so good when Cursor doesn't work sometimes or all the fast requests are used. https://www.youtube.com/watch?v=ly3bed99Dy8&lc=UgyyBt6_ShdDX_rIOad4AaABAg

Frequently Asked Questions

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

What is 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

I'm having trouble installing or using the tool. Where can I get help?
