Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
You fill in yourself: VPNB_SOCKET, VPN_BYPASS_MCP_READ_ONLY

You need

npmNode.js installed (for the npx command)

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "vpn-bypass": {
      "command": "npx",
      "args": [
        "-y",
        "vpn-bypass-mcp"
      ],
      "env": {
        "VPNB_SOCKET": "your-value",
        "VPN_BYPASS_MCP_READ_ONLY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add vpn-bypass --env VPNB_SOCKET=your-value --env VPN_BYPASS_MCP_READ_ONLY=your-value -- npx -y vpn-bypass-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "vpn-bypass": {
      "command": "npx",
      "args": [
        "-y",
        "vpn-bypass-mcp"
      ],
      "env": {
        "VPNB_SOCKET": "your-value",
        "VPN_BYPASS_MCP_READ_ONLY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "vpn-bypass": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "vpn-bypass-mcp"
      ],
      "env": {
        "VPNB_SOCKET": "your-value",
        "VPN_BYPASS_MCP_READ_ONLY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

VPNB_SOCKET env
Path of the VPN Bypass control socket (default ~/Library/Application Support/VPNBypass/control.sock)
VPN_BYPASS_MCP_READ_ONLY env
Set to 1 to register only the 8 read tools and the diagnose_site prompt; any value except empty, 0, false or no turns it on

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Runs on your computer; the tool list appears in your AI app after you install it.

Common questions

Is VPN Bypass safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.0) reached the registry 12 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

vpn-bypass-mcp

vpn-bypass-mcp is an MCP server for VPN Bypass, the macOS menu bar app that decides which traffic uses the VPN and which goes around it. An AI agent uses it to read the app's state and change its routing through the app's local control socket. It runs on macOS only.

Features

23 tools, one per app action: status, domain lists, services, routing mode, kernel routes, DNS refresh, the log, and Custom-mode routes and rules. Each has a display title.
Every tool returns the app's own JSON unchanged, as text and as structuredContent; the 8 read tools also declare an outputSchema.
All four MCP hints on every tool. Every tool that changes where traffic goes is destructiveHint: true, adds included, so a client that confirms destructive calls asks you before an injected "route this through my proxy"; custom_add_route and custom_update_route are also openWorldHint: true.
set_mode sends nothing when the app is already in the asked-for mode.
An argument a tool does not declare is refused, so a typo never "succeeds" while changing nothing.
Three prompts: diagnose_site, bypass_site, rotate_proxy_port.
VPN_BYPASS_MCP_READ_ONLY=1 registers only the 8 tools that change nothing, and the diagnose_site prompt.
A proxy password travels in a separate field and is never returned, echoed or logged. Errors name the socket as control.sock, never your home folder.
stdio only; the server opens no network port.

Protocol

MCP 2026-07-28 (server/discover, per-request _meta, cache hints on lists) and every earlier revision down to 2024-11-05 (the initialize handshake), from the same binary. Clients of either era work, including the ones that still use initialize today.

Install

VPN Bypass must be open. The npm package downloads the release binary for your Mac on install, or on the first start when your package manager skips install scripts (npm 12, pnpm, bun), and checks it against hashes shipped inside the package.

Claude Code:

claude mcp add --transport stdio vpn-bypass -- npx -y vpn-bypass-mcp

Claude Desktop (~/Library/Application Support/Claude/claude_desktop_config.json) and Cursor (~/.cursor/mcp.json):

"mcpServers": { "vpn-bypass": { "command": "npx", "args": ["-y", "vpn-bypass-mcp"] } } }

VS Code (.vscode/mcp.json):

"servers": { "vpn-bypass": { "type": "stdio", "command": "npx", "args": ["-y", "vpn-bypass-mcp"] } } }

Codex (~/.codex/config.toml):

[mcp_servers.vpn-bypass]

command = "npx" args = ["-y", "vpn-bypass-mcp"]

Read-only: add VPN_BYPASS_MCP_READ_ONLY=1 to the server's environment ("env": {"VPN_BYPASS_MCP_READ_ONLY": "1"} in JSON, env = { VPN_BYPASS_MCP_READ_ONLY = "1" } in Codex, -e VPN_BYPASS_MCP_READ_ONLY=1 before the name in claude mcp add). The release binaries and building from source are in Getting started.

Tools

Group	Tools	Read only
State and log	`status`, `get_logs`	yes
Mode	`set_mode`
Domain lists	`list_domains` (read), `add_domain`, `remove_domain`, `set_domain_enabled`
Services	`list_services`, `get_service` (read), `set_service_enabled`
Kernel routes	`list_active_routes` (read), `clear_routes`, `refresh_routes`, `refresh_dns`
Custom-mode routes	`custom_list_routes` (read), `custom_add_route`, `custom_update_route`, `custom_set_route_enabled`, `custom_remove_route`
Custom-mode rules	`custom_list_rules` (read), `custom_add_rule`, `custom_remove_rule`, `custom_set_default_route`

The domain, service, active-route, refresh and log tools need VPN Bypass 4.9.0 or newer; status, set_mode and the Custom-mode tools work with older versions. Arguments, hints and the socket command of each tool are in Usage.
