This is server that allows Claude desktop app to execute long-running terminal commands on your computer and manage processes through Model Context Protocol (MCP) + Built on top of MCP Filesystem Server to provide additional search and replace file editing capabilities .

Features

• Execute terminal commands with output streaming
• Command timeout and background execution support
• Process management (list and kill processes)
• Session management for long-running commands
• Full filesystem operations:
  • Read/write files
  • Create/list directories
  • Move files/directories
  • Search files
  • Get file metadata
  • Code editing capabilities:
  • Surgical text replacements for small changes
  • Full file rewrites for major changes
  • Multiple file support
  • Pattern-based replacements

Installation

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

Option 1: 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 2: Install trough npx

Just run this in terminal

npx @wonderwhy-er/desktop-commander setup

Restart Claude if running

Option 3: Add to claude_desktop_config by hand

Add this entry to your claude_desktop_config.json (on Mac, found at ~/Library/Application\ Support/Claude/claude_desktop_config.json):

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

Restart Claude if running

Option 4: 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

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: File operations
• create_directory/list_directory: Directory management
• move_file: Move/rename files
• search_files: Pattern-based file search
• get_file_info: File metadata

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
existing code to replace
=======
new code to insert
>>>>>>> REPLACE

Example:

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

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

Model Context Protocol Integration

This project extends the MCP Filesystem Server to enable:

• Local server support in Claude Desktop
• Full system command execution
• Process management
• File operations
• Code editing with search/replace blocks

Created as part of exploring Claude MCPs: https://youtube.com/live/TlbjFDbl5Us

Work in Progress and TODOs

The following features are currently being developed or planned:

• Better code search (in progress) - Enhanced code exploration with context-aware results
• Better configurations (in progress) - Improved settings for allowed paths, commands and shell environment
• Windows environment fixes (in progress) - Resolving issues specific to Windows platforms
• Linux improvements (in progress) - Enhancing compatibility with various Linux distributions
• Support for WSL - Windows Subsystem for Linux integration
• Support for SSH - Remote server command execution
• Installation troubleshooting guide - Comprehensive help for setup issues
