💾 Synology MCP Server

A Model Context Protocol (MCP) server for Synology NAS devices. Enables AI assistants to manage files and downloads through secure authentication and session management.

🌟 NEW: Unified server supports both Claude/Cursor (stdio) and Xiaozhi (WebSocket) simultaneously!

🚀 Quick Start with Docker

1️⃣ Setup Environment

# Clone repository
git clone https://github.com/atom2ueki/mcp-server-synology.git
cd mcp-server-synology

# Create environment file
cp env.example .env

2️⃣ Configure .env File

Basic Configuration (Claude/Cursor only):

# Required: Synology NAS connection
SYNOLOGY_URL=http://192.168.1.100:5000
SYNOLOGY_USERNAME=your_username
SYNOLOGY_PASSWORD=your_password

# Optional: Auto-login on startup
AUTO_LOGIN=true
VERIFY_SSL=false

Extended Configuration (Both Claude/Cursor + Xiaozhi):

# Required: Synology NAS connection
SYNOLOGY_URL=http://192.168.1.100:5000
SYNOLOGY_USERNAME=your_username
SYNOLOGY_PASSWORD=your_password

# Optional: Auto-login on startup
AUTO_LOGIN=true
VERIFY_SSL=false

# Enable Xiaozhi support
ENABLE_XIAOZHI=true
XIAOZHI_TOKEN=your_xiaozhi_token_here
XIAOZHI_MCP_ENDPOINT=wss://api.xiaozhi.me/mcp/

3️⃣ Run with Docker

One simple command supports both modes:

# Claude/Cursor only mode (default if ENABLE_XIAOZHI not set)
docker-compose up -d

# Both Claude/Cursor + Xiaozhi mode (if ENABLE_XIAOZHI=true in .env)
docker-compose up -d

# Build and run
docker-compose up -d --build

4️⃣ Alternative: Local Python

# Install dependencies
pip install -r requirements.txt

# Run with environment control
python main.py

🔌 Client Setup

{
  "mcpServers": {
    "synology": {
      "command": "docker-compose",
      "args": [

      }
    }
  }
}

🌟 Xiaozhi Integration

New unified architecture supports both clients simultaneously!

How It Works

• ENABLE_XIAOZHI=false (default): Standard MCP server for Claude/Cursor via stdio
• ENABLE_XIAOZHI=true: Multi-client bridge supporting both:
  • 📡 Xiaozhi: WebSocket connection
  • 💻 Claude/Cursor: stdio connection

Setup Steps

1. Add to your .env file:

ENABLE_XIAOZHI=true
XIAOZHI_TOKEN=your_xiaozhi_token_here

1. Run normally:

# Same command, different behavior based on environment
python main.py
# OR
docker-compose up

Key Features

• ✅ Zero Configuration Conflicts: One server, multiple clients
• ✅ Parallel Operation: Both clients can work simultaneously
• ✅ All Tools Available: Xiaozhi gets access to all Synology MCP tools
• ✅ Backward Compatible: Existing setups work unchanged
• ✅ Auto-Reconnection: Handles WebSocket connection drops
• ✅ Environment Controlled: Simple boolean flag to enable/disable

⚙️ Configuration Options

⚠️ Security Warning: Use a Dedicated Account

For this MCP server, create a dedicated Synology user account with appropriate permissions. This account should:

• NOT have 2FA enabled - The MCP server cannot handle 2FA prompts and will fail authentication
• Have minimal required permissions only (not admin!)
• Be used exclusively for MCP server automation

Using your primary account with 2FA is dangerous - if auto-login fails, you may be locked out of your NAS!

Using settings.json (Recommended)

*Required for auto-login and default operations

Using settings.json (Multi-NAS Support)

For managing multiple Synology NAS devices, use the XDG standard config directory (~/.config/synology-mcp/settings.json):

mkdir -p ~/.config/synology-mcp
touch ~/.config/synology-mcp/settings.json
chmod 600 ~/.config/synology-mcp/settings.json  # Important: secure permissions!

Note: This follows the XDG Base Directory Specification - ~/.config/ is the standard location for user configuration files on Linux/macOS. You can customize the location by setting the XDG_CONFIG_HOME environment variable.

With Docker:
The docker-compose.yml automatically mounts your ~/.config/synology-mcp directory into the container at /home/mcpuser/.config/synology-mcp, so multi-NAS works out of the box with Docker as well.

settings.json format:

{
  "synology": {
    "nas1": {
      "host": "192.168.1.100",
      "port": 5000,
      "username": "admin",
      "password": "your_password",
      "note": "Primary NAS at home"
    },
    "nas2": {
      "host": "192.168.1.200",
      "port": 5001,
      "username": "admin",
      "password": "your_password",
      "note": "Backup NAS"
    }
  },
  "xiaozhi": {
    "enabled": false,
    "token": "your_xiaozhi_token",
    "endpoint": "wss://api.xiaozhi.me/mcp/"
  },
  "server": {
    "auto_login": true,
    "verify_ssl": false,
    "session_timeout": 3600,
    "debug": false,
    "log_level": "INFO"
  }
}

Configuration fields:

Notes:

• The server will use port 5001 (HTTPS) if port is 5001, otherwise defaults to HTTP (5000)
• File permissions: chmod 600 ~/.config/synology-mcp/settings.json is required for security
• The server will refuse to load settings if permissions are too open
• Both .env and settings.json can be used together (settings.json takes priority)

⚠️ Security Recommendations

SSL Certificate Verification (VERIFY_SSL):

• Default is false to support self-signed certificates on internal NAS devices
• If your NAS has a valid SSL certificate (e.g., from Let's Encrypt or a corporate CA), set VERIFY_SSL=true
• Setting VERIFY_SSL=false disables certificate verification and makes your connection vulnerable to man-in-the-middle (MITM) attacks
• Never disable SSL verification on untrusted networks

Auto-Login (AUTO_LOGIN):

• Default is true for convenience with settings.json
• Credentials are stored securely in ~/.config/synology-mcp/settings.json with 0600 permissions
• If you prefer manual login, set AUTO_LOGIN=false and use the synology_login tool
