Terminal Controller MCP

A Model Context Protocol (MCP) server that enables secure terminal command execution, directory navigation, and file system operations through a standardized interface.

Features

• Command Execution: Run terminal commands with timeout controls and comprehensive output capture
• Directory Management: Navigate and list directory contents with intuitive formatting
• Security Measures: Built-in safeguards against dangerous commands and operations
• Command History: Track and display recent command executions
• Cross-Platform Support: Works on both Windows and UNIX-based systems

Installation

Prerequisites

• Python 3.11+
• An MCP-compatible client (such as Claude Desktop)
• UV/UVX installed (optional, for UVX method)

Method 1: PyPI Installation (Recommended)

Install the package directly from PyPI:

pip install terminal-controller

Or if you prefer to use UV:

uv pip install terminal-controller

Method 2: From Source

If you prefer to install from source:

1. Clone this repository:

git clone 
cd terminal-controller-mcp

2. Run the setup script:

python setup_mcp.py

Client Configuration

Claude Desktop

There are two ways to configure Claude Desktop to use Terminal Controller:

Option 1: Using UVX (Recommended)

Add this to your Claude Desktop configuration file:

"terminal-controller": {
 "command": "uvx",
 "args": ["terminal_controller"]

Option 2: Using Python Directly

"terminal-controller": {
 "command": "python",
 "args": ["-m", "terminal_controller"]

The configuration path varies by operating system:

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

Cursor

For Cursor, use similar configuration settings as Claude Desktop.

Other MCP Clients

For other clients, refer to their documentation on how to configure external MCP servers.

Usage

Once configured, you can use natural language to interact with your terminal through your MCP client:

• "Run the command ls -la in the current directory"
• "Navigate to my Documents folder"
• "Show me the contents of my Downloads directory"
• "Show me my recent command history"

API Reference

Terminal Controller exposes the following MCP tools:

execute_command

Execute a terminal command and return its results. Parameters:

• command: The command line command to execute
• timeout: Command timeout in seconds (default: 30) Returns:
• Output of the command execution, including stdout, stderr, and execution status

get_command_history

Get recent command execution history. Parameters:

• count: Number of recent commands to return (default: 10) Returns:
• Formatted command history record

get_current_directory

Get the current working directory. Returns:

• Path of current working directory

change_directory

Change the current working directory. Parameters:

• path: Directory path to switch to Returns:
• Operation result information

list_directory

List files and subdirectories in the specified directory. Parameters:

• path: Directory path to list contents (default: current directory) Returns:
• List of directory contents, formatted with icons for directories and files

Security Considerations

Terminal Controller implements several security measures:

• Timeout controls to prevent long-running commands
• Blacklisting of dangerous commands (rm -rf /, format, mkfs)
• Proper error handling and isolation of command execution
• Access only to the commands and directories specifically granted

Limitations

• Only commands that complete within the timeout period will return results
• By default, the server has access to the same file system permissions as the user running it
• Some interactive commands may not work as expected due to the non-interactive nature of the terminal interface

Troubleshooting

If you encounter issues:

1. Check that your Python version is 3.11 or higher
2. Verify that your Claude Desktop configuration is correct
3. Try running the terminal controller directly to check for errors:

python -m terminal_controller

4. For UVX-related issues, try:

uvx terminal_controller

5. Review your MCP client's logs for connection errors
