# mcp-wsl-exec
A Model Context Protocol (MCP) server for executing commands in
Windows Subsystem for Linux (WSL) environments. This server provides
secure command execution with built-in safety features and validation.
## Features
- 🔒 Secure command execution in WSL environments
- ⚡ Built-in safety features:
- Dangerous command detection
- Command confirmation system
- Path traversal prevention
- Command sanitization
- 📁 Working directory support
- ⏱️ Command timeout functionality
- 🔍 Detailed command output formatting
- ❌ Error handling and validation
- 🛡️ Protection against shell injection
## Configuration
This server requires configuration through your MCP client. Here are
examples for different environments:
### Cline Configuration
Add this to your Cline MCP settings:
```json
{
"mcpServers": {
"mcp-wsl-exec": {
"command": "npx",
"args": ["-y", "mcp-wsl-exec"]
}
}
}
```
### Claude Desktop Configuration
Add this to your Claude Desktop configuration:
```json
{
"mcpServers": {
"mcp-wsl-exec": {
"command": "npx",
"args": ["-y", "mcp-wsl-exec"]
}
}
}
```
## API
The server implements two MCP tools:
### execute_command
Execute a command in WSL with safety checks and validation.
Parameters:
- `command` (string, required): Command to execute
- `working_dir` (string, optional): Working directory for command
execution
- `timeout` (number, optional): Timeout in milliseconds
### confirm_command
Confirm execution of a dangerous command that was flagged by safety
checks.
Parameters:
- `confirmation_id` (string, required): Confirmation ID received from
execute_command
- `confirm` (boolean, required): Whether to proceed with the command
execution
## Safety Features
### Dangerous Command Detection
The server maintains a list of potentially dangerous commands that
require explicit confirmation before execution, including:
- File system operations (rm, rmdir, mv)
- System commands (shutdown, reboot)
- Package management (apt, yum, dnf)
- File redirections (>, >>)
- Permission changes (chmod, chown)
- And more...
### Command Sanitization
All commands are sanitized to prevent:
- Shell metacharacter injection
- Path traversal attempts
- Home directory references
- Dangerous command chaining
