Quick Start

Option 1: NPX (Recommended)

Run directly without installation:

# Explicit package syntax (most reliable)
npx --package=@hexsleeves/tailscale-mcp-server tailscale-mcp-server

# Or install globally
npm install -g @hexsleeves/tailscale-mcp-server
tailscale-mcp-server

Option 2: Docker

# GitHub Container Registry (recommended)
docker run -d \
  --name tailscale-mcp \
  -e TAILSCALE_API_KEY=your_api_key \
  -e TAILSCALE_TAILNET=your_tailnet \
  ghcr.io/hexsleeves/tailscale-mcp-server:latest

# Or use Docker Compose
docker-compose up -d

Configuration

Claude Desktop

Add to your Claude Desktop configuration (~/.claude/claude_desktop_config.json):

Using NPX (Recommended)

{
  "mcpServers": {
    "tailscale": {
      "command": "npx",
      "args": [
        "--package=@hexsleeves/tailscale-mcp-server",
        "tailscale-mcp-server"
      ],
      "env": {
        "TAILSCALE_API_KEY": "your-api-key-here",
        "TAILSCALE_TAILNET": "your-tailnet-name"
      }
    }
  }
}

Using Docker

{
  "mcpServers": {
    "tailscale": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "-e",
        "TAILSCALE_API_KEY=your-api-key",
        "-e",
        "TAILSCALE_TAILNET=your-tailnet",
        "ghcr.io/hexsleeves/tailscale-mcp-server:latest"
      ]
    }
  }
}

Environment Variables

Authentication (choose one method)

| Variable | Description | Required | | ------------------------------- | ----------------------------- | -------- | | TAILSCALE_API_KEY | Tailscale API key | Option 1 | | TAILSCALE_OAUTH_CLIENT_ID | OAuth client ID | Option 2 | | TAILSCALE_OAUTH_CLIENT_SECRET | OAuth client secret | Option 2 |

General Configuration

| Variable | Description | Required | Default | | ------------------------ | ---------------------- | -------- | --------------------------- | | TAILSCALE_TAILNET | Tailscale tailnet name | Yes* | - | | TAILSCALE_API_BASE_URL | API base URL | No | https://api.tailscale.com | | LOG_LEVEL | Logging level (0-3) | No | 1 (INFO) | | MCP_SERVER_LOG_FILE | Server log file path | No | - |

*Required for API-based operations. CLI operations work without API credentials.

OAuth vs API Key Authentication

API Key (TAILSCALE_API_KEY):

• Full permissions matching the user who created the key
• Expires in 1-90 days
• Tied to a specific user account

OAuth Client (TAILSCALE_OAUTH_CLIENT_ID + TAILSCALE_OAUTH_CLIENT_SECRET):

• Scoped permissions (e.g., read-only device access)
• Does not expire (but can be revoked)
• Not tied to any user account
• Recommended for automation and least-privilege access

Creating an OAuth Client

1. Go to Tailscale OAuth Settings
2. Click "Generate OAuth client"
3. Select the required scopes (e.g., devices:read for read-only device access)
4. Copy the client ID and secret

OAuth Configuration Example

{
  "mcpServers": {
    "tailscale": {
      "command": "npx",
      "args": [
        "--package=@hexsleeves/tailscale-mcp-server",
        "tailscale-mcp-server"
      ],
      "env": {
        "TAILSCALE_OAUTH_CLIENT_ID": "your-oauth-client-id",
        "TAILSCALE_OAUTH_CLIENT_SECRET": "your-oauth-client-secret",
        "TAILSCALE_TAILNET": "your-tailnet-name"
      }
    }
  }
}

Available OAuth Scopes

| Scope | Description | | ------------------ | ------------------------------------ | | all:read | Read-only access to all resources | | devices:read | Read device information | | devices:core | Full device management | | dns:read | Read DNS settings | | dns:write | Modify DNS settings | | acl:read | Read ACL configuration | | acl:write | Modify ACL configuration | | auth_keys | Manage authentication keys |

See Tailscale OAuth Scopes for a complete list.
