Overview

MCP Shell Server is a secure shell command execution server that implements the Model Context Protocol (MCP), allowing remote execution of whitelisted shell commands with stdin input support.

To use the MCP Shell Server, install it via pip and start the server by specifying allowed commands through the ALLOW_COMMANDS environment variable. You can then submit commands using an API request format.

  • Secure execution by whitelisting available commands. - Supports standard input for command execution. - Comprehensive output including stdout, stderr, exit status, and execution time. - Validates commands to avoid unsafe operations. - Provides timeout control for command execution.
  1. Remote execution of maintenance commands in secure environments.
  2. Integration with other applications that need controlled command execution.
  3. Allowing users to execute various shell commands safely without direct shell access.

Cursor

Add this to your .cursor/mcp.json file in your project root, then restart Cursor.

.cursor/mcp.json

{
  "mcpServers": {
    "mcp-shell-server-tumf": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-shell-server-tumf"
      ]
    }
  }
}

Claude Desktop

Add this server entry to the mcpServers object in your Claude Desktop config, then restart the app.

~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows)

{
  "mcpServers": {
    "mcp-shell-server-tumf": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-mcp-shell-server-tumf"
      ]
    }
  }

      ]
    }
  }
}

VS Code (Copilot)

Add this to your .vscode/mcp.json file. Requires the GitHub Copilot extension with MCP support enabled.

.vscode/mcp.json

{

      ]
    }
  }
}
