What is CLI MCP Server?

A secure Model Context Protocol (MCP) server implementation for executing controlled command-line operations with comprehensive security features. It enables LLM applications to run whitelisted CLI commands within allowed directories, providing controlled CLI access while maintaining security.

How to use CLI MCP Server?

Install via Smithery (npx @smithery/cli install cli-mcp-server --client claude) or manually configure for Claude Desktop by adding a mcpServers entry in claude_desktop_config.json using uv or uvx. Set environment variables (ALLOWED_DIR, ALLOWED_COMMANDS, ALLOWED_FLAGS, MAX_COMMAND_LENGTH, COMMAND_TIMEOUT) to define restrictions. Then use the run_command tool to execute whitelisted commands or show_security_rules to view current security settings.

Key features of CLI MCP Server

Secure command execution with strict validation
Configurable command and flag whitelisting
Path traversal prevention and shell operator injection protection
Execution timeouts and command length limits
Detailed error reporting for security violations and failures
Async operation support

Use cases of CLI MCP Server

Allow an AI assistant to run ls, cat, and pwd in a sandboxed directory
Prevent unauthorized commands by enforcing a whitelist of allowed commands and flags
Enforce execution timeouts and command length limits for safety
