Installation

Installing via Smithery

To install Terminal Controller for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @GongRzhe/terminal-controller-mcp --client claude

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:

Clone this repository:

git clone https://github.com/GongRzhe/terminal-controller-mcp.git
cd terminal-controller-mcp

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"
"Read the content of config.json"
"Update line 5 in my script.py file with 'print("Hello World")'"
"Delete lines 10-15 from the log file"
"Insert a new line at the beginning of my text file"

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:

Check that your Python version is 3.11 or higher
Verify that your Claude Desktop configuration is correct
Try running the terminal controller directly to check for errors:
```
python -m terminal_controller
```
For UVX-related issues, try:
```
uvx terminal_controller
```
Review your MCP client's logs for connection errors
