claude-mcp-tunnel
An MCP server that exposes your local dev servers to your phone through Claude Desktop.
Text Claude from your phone: "Start my project and give me a link" — get back a working URL.
Zero accounts. Zero config. Works with 25+ frameworks.
What Is This?
An MCP (Model Context Protocol) server that gives Claude Desktop the ability to:
Detect what framework your project uses (Next.js, Vite, FastAPI, etc.)
Start the dev server and install dependencies if needed
Tunnel it so your phone (or anyone) can reach it
Return the URL so you can open it immediately
It also ships as a standalone CLI (npx claude-mcp-tunnel) for use without Claude.
Quick Start — MCP Server (Claude Desktop)
Option A: Install via npm (easiest)
npm install -g claude-mcp-tunnelThen add to your Claude Desktop config:
macOS:
~/Library/Application Support/Claude/claude_desktop_config.jsonWindows:
%APPDATA%\Claude\claude_desktop_config.json
{
"mcpServers": {
"claude-mcp-tunnel": {
"command": "claude-mcp-tunnel-server"
}
}
}Option B: Clone from GitHub
git clone https://github.com/AustinRyan/claude-mcp-tunnel.git
cd claude-mcp-tunnel
npm installThen add to your Claude Desktop config:
{
"mcpServers": {
"claude-mcp-tunnel": {
"command": "node",
"args": ["/absolute/path/to/claude-mcp-tunnel/mcp-server/index.js"]
}
}
}Replace /absolute/path/to/claude-mcp-tunnel with where you cloned the repo.
Install cloudflared (required for public tunnels)
# macOS
brew install cloudflared
# Linux
curl -L https://github.com/cloudflare/cloudflared/releases/latest/download/cloudflared-linux-amd64 -o /usr/local/bin/cloudflared && chmod +x /usr/local/bin/cloudflaredRestart Claude Desktop
Close and reopen Claude Desktop. The tools will appear automatically.
Use it
In Claude Desktop, say:
"Expose port 3000 and give me a URL"
or
"Start the project at /path/to/my-app and give me a link I can open on my phone"
MCP Tools
Tool | Description |
| Scan common dev ports (3000, 5173, 8080, etc.) for running servers |
| Detect project framework from a directory |
| Expose a running port via tunnel, return a public URL |
| Full pipeline: detect framework, install deps, start server, tunnel, return URL |
| Start both backend + frontend for full-stack projects, expose frontend |
| Kill all active tunnels and servers |
| Show all active tunnels, ports, and URLs |
Example: Full-Stack Project
For a project with a FastAPI backend and Vite frontend:
"Start the full stack project at /path/to/my-app — the frontend is in the
frontend/directory, the backend runs withuvicorn backend.app:app --reload --port 8000"
Claude calls start_full_stack → starts backend on 8000 → starts frontend on 5173 → tunnels the frontend → returns the URL.
Use with Claude Dispatch
Text from your phone via Dispatch:
"Start my project and give me a link I can open on my phone"
The flow:
Phone → Dispatch → Cowork (your Mac) → MCP tool → URL back to phoneClaude calls start_and_expose, gets the tunnel URL, and texts it back to you.
Standalone CLI (No Claude Required)
Works as a regular CLI tool for anyone:
# Use directly (no install needed)
npx claude-mcp-tunnel
# Or install globally
npm install -g claude-mcp-tunnelCLI Commands
# Auto-detect running server and expose it
claude-mcp-tunnel
# Expose a specific port
claude-mcp-tunnel 3000
# Detect project, install deps, start server, expose — all in one
claude-mcp-tunnel start
# Scan what's running on common dev ports
claude-mcp-tunnel scan
# Get your local IP
claude-mcp-tunnel ipCLI Flags

Tunnel Backends
Auto-selects the best available backend. No accounts required for any of them.
Backend | Speed | Install Required | Access |
Cloudflare Tunnel | Fast |
| Public HTTPS (anywhere) |
bore | Fast |
| Public (anywhere) |
localtunnel | Good | None (pure Node.js) | Public (anywhere) |
localhost.run | Good | None (uses SSH) | Public (anywhere) |
Local IP | Instant | None | Same WiFi only |
Fallback order: Cloudflare → bore → localtunnel → localhost.run → local IP.
Cloudflare Tunnel is recommended — it produces HTTPS URLs on a trusted domain (trycloudflare.com) that ISPs and security software won't block.
Supported Frameworks (25+)
Node.js: Next.js, Vite, Create React App, Angular, Vue CLI, SvelteKit, Gatsby, Remix, Nuxt, Astro, Express, Fastify, NestJS, Storybook, Docusaurus, Eleventy
Python: FastAPI, Flask, Django, Streamlit
Other: Rust (Cargo), Go, Ruby on Rails, Laravel (PHP), Hugo, Jekyll, Static HTML
Automatically detects the framework, determines the correct start command, and handles package manager differences (npm, yarn, pnpm, bun).

Problem | Solution |
Tools don't appear in Claude Desktop | Restart Claude Desktop. If using npm, verify |
"Cannot find module" errors | Run |
Tunnel URL blocked by ISP | Install cloudflared ( |
Vite "host not allowed" error | Add |
Tunnel fails, only local IP works | Install cloudflared. Without it, falls back to bore → localtunnel → SSH → local IP. |
Server starts but wrong port | Check your project's config (e.g. |
MCP server crashes silently | Check Claude Desktop's MCP logs. Server logs go to stderr. |
