Terminal Command Execution for AI Models

Overview

Terminal MCP Server is a Model Context Protocol (MCP) server that allows executing commands on local or remote hosts. It provides a simple yet powerful interface for AI models and other applications to execute system commands, either on the local machine or on remote hosts via SSH.

Features

• Local Command Execution: Execute commands directly on the local machine
• Remote Command Execution: Execute commands on remote hosts via SSH
• Session Persistence: Support for persistent sessions that reuse the same terminal environment for a specified time (default 20 minutes)
• Environment Variables: Set custom environment variables for commands
• Multiple Connection Methods: Connect via stdio or SSE (Server-Sent Events)

Installation

Installing via Smithery

To install terminal-mcp-server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @weidwonder/terminal-mcp-server --client claude

Manual Installation

# Clone the repository
git clone https://github.com/weidwonder/terminal-mcp-server.git
cd terminal-mcp-server

# Install dependencies
npm install

# Build the project
npm run build

Usage

Starting the Server

# Start the server using stdio (default mode)
npm start

# Or run the built file directly
node build/index.js

Starting the Server in SSE Mode

The SSE (Server-Sent Events) mode allows you to connect to the server remotely via HTTP.

# Start the server in SSE mode
npm run start:sse

# Or run the built file directly with SSE flag
node build/index.js --sse

Testing with MCP Inspector

# Start the MCP Inspector tool
npm run inspector

The execute_command Tool

The execute_command tool is the core functionality provided by Terminal MCP Server, used to execute commands on local or remote hosts.

Configuring with AI Assistants

Configuring with Roo Code

3. Add the following configuration:

For stdio mode (local connection)

{
  "mcpServers": {
    "terminal-mcp": {
      "command": "node",
      "args": ["/path/to/terminal-mcp-server/build/index.js"],
      "env": {}
    }
  }
}

For SSE mode (remote connection)

{
  "mcpServers": {
    "terminal-mcp-sse": {
      "url": "http://localhost:8080/sse",
      "headers": {}
    }
  }
}

Configuring with Cline

1. Open the Cline settings file: ~/.cline/config.json
2. Add the following configuration:

For stdio mode (local connection)

{
  "mcpServers": {
    "terminal-mcp": {
      "command": "node",
      "args": ["/path/to/terminal-mcp-server/build/index.js"],
      "env": {}
    }
  }
}

For SSE mode (remote connection)

{
  "mcpServers": {
    "terminal-mcp-sse": {
      "url": "http://localhost:8080/sse",
      "headers": {}
    }
  }
}

Configuring with Claude Desktop

1. Open the Claude Desktop settings file: ~/Library/Application Support/Claude/claude_desktop_config.json
2. Add the following configuration:

For stdio mode (local connection)

{
  "mcpServers": {
    "terminal-mcp": {
      "command": "node",
      "args": ["/path/to/terminal-mcp-server/build/index.js"],
      "env": {}
    }
  }
}

For SSE mode (remote connection)

{
  "mcpServers": {
    "terminal-mcp-sse": {
      "url": "http://localhost:8080/sse",
      "headers": {}
    }
  }
}

Best Practices

Command Execution

• Before running commands, it's best to determine the system type (Mac, Linux, etc.)
• Use full paths to avoid path-related issues
• For command sequences that need to maintain environment, use && to connect multiple commands
• For long-running commands, consider using nohup or screen/tmux

SSH Connection

• Ensure SSH key-based authentication is set up
• If connection fails, check if the key file exists (default path: ~/.ssh/id_rsa)
• Make sure the SSH service is running on the remote host

Session Management

• Use the session parameter to maintain environment between related commands
• For operations requiring specific environments, use the same session name
• Note that sessions will automatically close after 20 minutes of inactivity

Error Handling

• Command execution results include both stdout and stderr
• Check stderr to determine if the command executed successfully
• For complex operations, add verification steps to ensure success

Important Notes

• For remote command execution, SSH key-based authentication must be set up in advance
• For local command execution, commands will run in the context of the user who started the server
• Session timeout is 20 minutes, after which the connection will be automatically closed
