Claude Computer Commander

Short version. Two key things. Terminal commands and diff based file editing.

This 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 file editing capabilities .

• 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

1. Clone and build:

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

The setup command will:

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

The server provides these tool categories:

• 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

• 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_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

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

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
