How to Set Up and Use FRITZ!Box

The FRITZ!Box MCP Server exposes over 143 tools for controlling your AVM FRITZ!Box home router and connected smart home devices through any MCP-compatible AI assistant. Written in Go, it communicates with your router entirely over the local network — credentials never leave your home — and supports all FRITZ!Box models through runtime-driven tool discovery.

Prerequisites

  • AVM FRITZ!Box router accessible on the local network (any model)
  • FRITZ!Box user account with 'FRITZ!Box-Einstellungen' (full settings) permissions enabled
  • MCP-compatible client such as Claude Desktop
  • Linux or macOS (automated install script), or Windows (manual binary download)
  • Go 1.25+ only if building from source
1

Install the FRITZ!Box MCP server

Use the automated install script on Linux or macOS. The script downloads the correct binary for your platform, places it in /usr/local/bin, and makes it executable.

curl -fsSL https://raw.githubusercontent.com/kambriso/fritzbox-mcp-server/main/install.sh | sh
2

Enable router user permissions

In your FRITZ!Box web UI, navigate to System → FRITZ!Box-Benutzer, select your user, and enable the 'The user can view and edit all FRITZ!Box settings' checkbox (FRITZ!Box-Einstellungen). Save and apply.

3

Run interactive setup

Run the server's interactive setup wizard. It auto-discovers your router, prompts for credentials, and saves them to a .env file with restricted permissions (0600).

./fritz-mcp --setup
4

Configure environment variables manually (optional)

If you prefer manual configuration, create a .env file in the same directory as the binary with the following variables.

FRITZ_HOST=fritz.box
FRITZ_PORT=49000
FRITZ_USERNAME=your_fritz_username
FRITZ_PASSWORD=your_fritz_password
5

Add to Claude Desktop configuration

Register the FRITZ!Box MCP server in your Claude Desktop config file using the absolute path to the fritz-mcp binary.

{
  "mcpServers": {
    "fritzbox": {
      "command": "/usr/local/bin/fritz-mcp"
    }
  }
}

FRITZ!Box Examples

Client configuration

Add this block to your claude_desktop_config.json. The binary reads credentials from the .env file in its working directory or from environment variables.

{
  "mcpServers": {
    "fritzbox": {
      "command": "/usr/local/bin/fritz-mcp",
      "env": {
        "FRITZ_HOST": "fritz.box",
        "FRITZ_USERNAME": "admin",
        "FRITZ_PASSWORD": "your_password"
      }
    }
  }
}

Prompts to try

Ask Claude these questions after connecting the FRITZ!Box MCP server.

- "Analyze my network health and check if everything is running optimally"
- "Show me all WiFi devices and which are using the most bandwidth"
- "Block the Nintendo Switch in 20 minutes"
- "Why is my internet connection slow right now?"

Troubleshooting FRITZ!Box

Cannot connect to FRITZ!Box

Run 'ping fritz.box' to verify the hostname resolves. If it does not, use the router's IP address (typically 192.168.178.1) as FRITZ_HOST instead. Confirm credentials are correct by logging into the FRITZ!Box web UI at http://fritz.box.

MCP server not visible in Claude Desktop

Ensure the command path in claude_desktop_config.json is an absolute path to the fritz-mcp binary (not a relative path). Restart Claude Desktop fully after editing the config file.

Permission errors when calling tools

The FRITZ!Box user account must have 'FRITZ!Box-Einstellungen' (full settings access) enabled. Log into the FRITZ!Box web UI, go to System → FRITZ!Box-Benutzer, select the user, and enable the full settings checkbox.
