The Terminal MCP Server enables AI models and applications to execute commands on local or remote systems with advanced session management and integration capabilities.
Local & Remote Execution: Run commands directly on the host machine or on remote systems via SSH
Session Persistence: Maintain consistent terminal environments using named sessions that auto-close after 20 minutes of inactivity
Environment Variables: Set custom environment variables for tailored execution contexts
Flexible Connectivity: Connect via stdio for local integration or Server-Sent Events (SSE) for remote HTTP-based communication
AI Assistant Integration: Configure with tools like Claude Desktop, Roo Code, and Cline for AI-driven command execution
Terminal MCP Server
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
You can customize the SSE server with the following command-line options:
Option | Description | Default |
or
| The port to listen on | 8080 |
or
| The endpoint path | /sse |
or
| The host to bind to | localhost |
Example with custom options:
# Start SSE server on port 3000, endpoint /mcp, and bind to all interfaces
node build/index.js --sse --port 3000 --endpoint /mcp --host 0.0.0.0
This will start the server and listen for SSE connections at http://0.0.0.0:3000/mcp.
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.
Parameters
Parameter | Type | Required | Description |
command | string | Yes | The command to execute |
host | string | No | The remote host to connect to. If not provided, the command will be executed locally |
username | string | Required when host is specified | The username for SSH connection |
session | string | No | Session name, defaults to "default". The same session name will reuse the same terminal environment for 20 minutes |
env | object | No | Environment variables, defaults to an empty object |
Examples
Executing a Command Locally
{
"command": "ls -la",
"session": "my-local-session",
"env": {
"NODE_ENV": "development"
}
}
Executing a Command on a Remote Host
{
"host": "example.com",
"username": "user",
"command": "ls -la",
"session": "my-remote-session",
"env": {
"NODE_ENV": "production"
}
}
Configuring with AI Assistants
Configuring with Roo Code
Open VSCode and install the Roo Code extension
Open the Roo Code settings file:
~/Library/Application Support/Code/User/globalStorage/rooveterinaryinc.roo-cline/settings/cline_mcp_settings.jsonAdd 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": {}
}
}
}
Replace localhost:8080/sse with your actual server address, port, and endpoint if you've customized them.
Configuring with Cline
Open the Cline settings file:
~/.cline/config.jsonAdd 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
Open the Claude Desktop settings file:
~/Library/Application Support/Claude/claude_desktop_config.jsonAdd 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 commandsFor long-running commands, consider using
nohuporscreen/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
hybrid server
The server is able to function both locally and remotely, depending on the configuration or use case.
