mullvad-mcp

An MCP (Model Context Protocol) server for controlling Mullvad VPN through any MCP-compatible client — Claude Desktop, Cursor, Windsurf, and more.

All VPN interaction goes through the mullvad CLI. No direct API calls, no config file parsing, no credentials needed.

Prerequisites

• Mullvad VPN app installed with the CLI available in your PATH
  • Verify: mullvad --version
  • Download Mullvad
• Python 3.11+
• uv package manager — install uv

Installation

git clone https://github.com/your-username/mullvad-mcp.git
cd mullvad-mcp
uv sync

Client Configuration

Claude Desktop

Add to ~/.config/claude-desktop/claude_desktop_config.json (Linux) or ~/Library/Application Support/Claude/claude_desktop_config.json (macOS):

{
  "mcpServers": {
    "mullvad": {
      "command": "uv",
      "args": ["--directory", "/path/to/mullvad-mcp", "run", "mullvad-mcp"]
    }
  }
}

Cursor

Add to .cursor/mcp.json in your project or ~/.cursor/mcp.json globally:

{
  "mcpServers": {
    "mullvad": {
      "command": "uv",
      "args": ["--directory", "/path/to/mullvad-mcp", "run", "mullvad-mcp"]
    }
  }
}

Generic MCP Client (stdio)

{
  "mcpServers": {
    "mullvad": {
      "command": "uv",
      "args": ["--directory", "/path/to/mullvad-mcp", "run", "mullvad-mcp"],
      "transport": "stdio"
    }
  }
}

Example Interactions

Connection

"Connect me to Sweden"

→ Calls connect(country="se") — sets relay to Sweden and connects.

Status Check

"Am I leaking?"

→ Calls check_leak() — queries am.i.mullvad.net and reports whether traffic exits through Mullvad.

Server Selection

"What cities are available in Germany?"

→ Calls list_cities(country="de") — returns Berlin, Frankfurt, etc. with server counts.

Settings

"Enable the kill switch and block ads"

→ Calls set_killswitch(enabled=True) then set_dns(block_ads=True).

Environment Variables

Variable	Default	Description
MULLVAD_CLI_PATH	Auto-detected	Override path to the mullvad binary
MULLVAD_CLI_TIMEOUT	10	CLI command timeout in seconds

How It Works

All tools call the mullvad CLI via subprocess. The CLI handles authentication natively — no API keys or secrets are needed. Output is parsed into structured dicts so LLMs can reason about the results.
