Configuration

Gemini CLI

Option A: Using stdio transport (default)

{
  "mcpServers": {
    "node-terminal-mcp": {
      "command": "npx",
      "args": ["-y", "@hazzel-cn/node-terminal-mcp@latest"],
      "env": {}
    }
  }
}

Option B: If you get "Connection closed" errors with ADK, try this:

{
  "mcpServers": {
    "node-terminal-mcp": {
      "command": "npx",
      "args": ["-y", "@hazzel-cn/node-terminal-mcp@latest"],
      "env": {},
      "timeout": 30000
    }
  }
}

Option C: Alternative workaround for persistent connection issues:

{
  "mcpServers": {
    "node-terminal-mcp": {
      "command": "bash",
      "args": ["-c", "npx -y @hazzel-cn/node-terminal-mcp"],
      "env": {}
    }
  }
}

Google ADK

Option A: Using npx (recommended)

{
  "mcpServers": {
    "node-terminal-mcp": {
      "command": "npx",
      "args": ["-y", "@hazzel-cn/node-terminal-mcp@latest"],
      "env": {}
    }
  }
}

Option B: Using global installation (recommended)

npm install -g @hazzel-cn/node-terminal-mcp

{
  "mcpServers": {
    "node-terminal-mcp": {
      "command": "node-terminal-mcp",
      "args": [],
      "env": {}
    }
  }
}

Usage

The server provides the following MCP tools:

• create_terminal: Create a new terminal session
• write_to_terminal: Send input to a terminal session
• send_key_to_terminal: Send special keys to a terminal session
• read_from_terminal: Read output from a terminal session
• resize_terminal: Resize a terminal session
• list_terminals: List all active terminal sessions
• close_terminal: Close a terminal session

Architecture

• TerminalManager: Manages multiple terminal sessions using node-pty
• PTY Integration: Uses node-pty for terminal emulation and process management
• MCP Server: Provides standardized interface for AI agents

Requirements

• Node.js 18+
• Compatible with MCP (Model Context Protocol) clients

Troubleshooting

ADK "Connection Closed" Issue

If you're experiencing "Connection closed" errors with Google ADK, this is a known issue with stdio transport. Try these solutions:

1. Use the latest version:

{
  "mcpServers": {
    "node-terminal-mcp": {
      "command": "npx",
      "args": ["-y", "@hazzel-cn/node-terminal-mcp@latest"],
      "env": {},
      "timeout": 30000
    }
  }
}

2. Install globally:

npm install -g @hazzel-cn/node-terminal-mcp

{
  "mcpServers": {
    "node-terminal-mcp": {
      "command": "node-terminal-mcp",
      "args": [],
      "env": {}
    }
  }
}

3. Use bash wrapper:

{
  "mcpServers": {
    "node-terminal-mcp": {
      "command": "bash",
      "args": ["-c", "npx -y @hazzel-cn/node-terminal-mcp@latest"],
      "env": {}
    }
  }
}
