No more lost tunnels. Easy management of multiple tunnels. ## ⚠️ Disclaimer This project uses the [untun](https://github.com/unjs/untun) package from npm but is **not** officially affiliated with, endorsed by, or connected to Cloudflare or UnJS. This is an independent, community-developed MCP wrapper around the untun CLI tool. ## 🛠️ Getting Started ### Requirements - Node.js >= v18.0.0 - MCP-compatible client (Cursor, Claude Desktop, VS Code, etc.) - `untun` CLI tool (installed automatically as needed) ### Install in Cursor Go to: `Settings` -> `Cursor Settings` -> `MCP` -> `Add new global MCP server` Paste the following configuration into your Cursor `~/.cursor/mcp.json` file: ```json { "mcpServers": { "untun": { "command": "npx", "args": ["-y", "@minte-app/untun-mcp@latest"] } } } ``` ### Install in VS Code [Install in VS Code (npx)](https://insiders.vscode.dev/redirect?url=vscode%3Amcp%2Finstall%3F%7B%22name%22%3A%22untun%22%2C%22command%22%3A%22npx%22%2C%22args%22%3A%5B%22-y%22%2C%22%40minte-app%2Funtun-mcp%40latest%22%5D%7D) Add this to your VS Code MCP config file: ```json { "servers": { "Untun": { "type": "stdio", "command": "npx", "args": ["-y", "@minte-app/untun-mcp@latest"] } } } ``` ### Installing via Smithery To install Untun Secure Tunnel Manager for Claude Desktop automatically via [Smithery](https://smithery.ai/server/@minte-app/untun-mcp): ```bash npx -y @smithery/cli install @minte-app/untun-mcp --client claude ``` ### Install in Claude Desktop Add this to your Claude Desktop `claude_desktop_config.json` file: ```json { "mcpServers": { "Untun": { "command": "npx", "args": ["-y", "@minte-app/untun-mcp@latest"] } } } ``` ## 🔨 How to Use Ask your AI assistant to create a tunnel with natural language: ``` Create a tunnel to my localhost:3000 server ``` Check your running tunnels: ``` Show me all my active tunnels ``` Stop a specific tunnel: ``` Stop the tunnel to localhost:3000 ``` ## Available Tools - `start_tunnel`: Creates a secure tunnel from a public internet address to your local server - `url` (required): The local URL to expose (e.g., http://localhost:3000) - `name` (optional): Custom name for the tunnel - `stop_tunnel`: Stops a running tunnel or all local tunnels - `name` (optional): Name of a specific tunnel to stop - `list_tunnels`: Lists all active tunnels including their status and details ## Troubleshooting ### Tunnel Not Starting If your tunnel doesn't start, try these steps: 1. Make sure your local server is running 2. Check if there's already a tunnel running for that port 3. Use `list_tunnels` to check the status of all tunnels ### Remote Tunnels Tunnels are tracked by hostname. If you see "remote" tunnels that can't be stopped, they are likely running on another machine. You'll need to stop them from the original machine. ## Development Clone the project and install dependencies: ```bash npm install ``` Build: ```bash npm run build ``` ## License MIT
