What is the Untun MCP MCP server?

If you want an AI assistant working directly with Untun MCP, the untun mcp mcp server is the bridge. MCP server for untun integration.

What Untun MCP does

No complex CLI commands to remember. No more lost tunnels. Easy management of multiple tunnels.

Tools it exposes

Once connected, the assistant can call these 4 tools directly:

  • start_tunnel — Creates a secure tunnel from a public internet address to your local server
  • stop_tunnel — Stops a running tunnel or all local tunnels
  • list_tunnels — Lists all active tunnels including their status and details
  • Requirements — The Requirements tool exposed by this server

Installing the untun mcp mcp server

The server is distributed via npm as @smithery/cli, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.

Requirements

  • Node.js >= v18.0.0 - MCP-compatible client (Cursor, Claude Desktop, VS Code, etc.) - untun CLI tool (installed automatically as needed)

Where it fits

Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. Untun MCP sits in that group, and the shape of its toolset — start_tunnel, stop_tunnel, list_tunnels among others — tells you what it is really for. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.

Practical notes

  • This server runs locally, so it operates with whatever access your machine and its credentials already have. Scope that deliberately rather than by default.
  • Maintained by minte-app, written in Go.
  • MCP clients ask for confirmation before each tool call by default. Keep that on while you learn what the untun mcp mcp server actually does with your data.
  • Every entry in this directory is reviewed by hand before it goes live, and details are checked against the project's own documentation.

Frequently asked questions

It connects Untun MCP to MCP-compatible AI assistants such as Claude and Cursor, exposing 4 tools (start_tunnel, stop_tunnel, list_tunnels, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Untun MCP directly.
