📦 Available Packages

• NPM: @hexsleeves/tailscale-mcp-server
• Docker Hub: hexsleeves/tailscale-mcp-server
• GitHub Container Registry: ghcr.io/hexsleeves/tailscale-mcp-server

Features

• Device Management: List, authorize, deauthorize, and manage Tailscale devices
• Network Operations: Connect/disconnect, manage routes, and monitor network status
• Security Controls: Manage ACLs, device tags, and network lock settings
• Modern Architecture: Modular tool system with TypeScript and Zod validation
• CLI Integration: Direct integration with Tailscale CLI commands
• API Integration: REST API support for advanced operations

Quick Start

Option 1: NPX (Recommended)

Run directly without installation:

# Method 1: Explicit package syntax (most reliable)
npx --package=@hexsleeves/tailscale-mcp-server tailscale-mcp-server

# Method 2: Direct syntax (may work depending on npx version)
npx -y @hexsleeves/tailscale-mcp-server

Note: Method 1 with --package= syntax is more reliable across different npx versions and environments.

Or install globally:

npm install -g @hexsleeves/tailscale-mcp-server
tailscale-mcp-server

Option 2: Docker

Docker Hub

# Pull and run from Docker Hub
docker run -d \
  --name tailscale-mcp \
  -e TAILSCALE_API_KEY=your_api_key \
  -e TAILSCALE_TAILNET=your_tailnet \
  hexsleeves/tailscale-mcp-server:latest

GitHub Container Registry

# Pull and run from GitHub Container Registry
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

Publishing

The project includes an interactive publishing script that handles version bumping and publishing to multiple registries:

# Run the interactive publish script
npm run publish

# Or run directly
./scripts/publish.sh

The script will guide you through:

1. Version Bumping: Choose between patch, minor, major, or skip
2. NPM Publishing: Optionally publish to npm registry
3. Docker Hub: Optionally build and publish Docker images
4. GitHub Container Registry: Optionally publish to GHCR
5. Git Operations: Automatically commit version changes and create tags

Publishing Features

• Interactive prompts for each publishing step
• Automatic version bumping with semantic versioning
• Git integration with automatic tagging and commits
• Multi-registry support (npm, Docker Hub, GHCR)
• Safety checks for uncommitted changes
• Colored output for better visibility
• Error handling with proper exit codes
• Performance optimized with pre-calculated version previews

Prerequisites for Publishing

• NPM: Logged in with npm login and proper access to the package
• Docker Hub: Logged in with docker login
• GHCR: Logged in with docker login ghcr.io using a GitHub token
• Git: Clean working directory (or confirmation to proceed with uncommitted changes)

Docker Development

For Docker-based development:

# Build development image
docker build -t tailscale-mcp-dev .

# Run with development environment
docker run -it --rm \
  -v $(pwd):/app \
  -v /app/node_modules \
  -e TAILSCALE_API_KEY=your_api_key \
  -e TAILSCALE_TAILNET=your_tailnet \
  -e LOG_LEVEL=0 \
  tailscale-mcp-dev

# Or use Docker Compose for development
docker-compose -f docker-compose.dev.yml up

Adding New Tools

1. Create a new tool module in src/tools/:

import { z } from "zod";
import type { ToolModule, ToolContext } from "./index.js";

const MyToolSchema = z.object({
  param: z.string().describe("Description of parameter"),
});

async function myTool(
  args: z.infer<typeof MyToolSchema>,
  context: ToolContext,
) {
  // Implementation
  return {
    content: [{ type: "text", text: "Result" }],
  };
}

export const myTools: ToolModule = {
  tools: [
    {
      name: "my_tool",
      description: "Description of what this tool does",
      inputSchema: MyToolSchema,
      handler: myTool,
    },
  ],
};

1. Register the module in src/server.ts:

import { myTools } from "./tools/my-tools.js";

// In the constructor:
this.toolRegistry.registerModule(myTools);

Debugging

Enable debug logging for development:

# Set environment variable
export LOG_LEVEL=0

# Or in .env file
LOG_LEVEL=0
MCP_SERVER_LOG_FILE=debug-{timestamp}.log

View logs in real-time:

# Follow server logs
tail -f logs/debug-*.log

# Or use Docker logs
docker-compose logs -f tailscale-mcp
