Firewalla MCP Server

Firewalla MCP Server - Claude integration for network security monitoring and firewall management

Installation

Add the following to your MCP client configuration file.

Configuration

{
  "mcpServers": {
    "amittell-firewalla-mcp-server": {
      "url": "http://localhost:3000/mcp",
      "headers": {
        "FIREWALLA_BOX_ID": "your_box_gid_here",
        "FIREWALLA_MSP_ID": "yourdomain.firewalla.net",
        "FIREWALLA_MSP_TOKEN": "your_msp_access_token_here"
      }
    }
  }
}

You can run a Firewalla MCP Server to access real-time Firewalla firewall data through a suite of tools. It connects Claude-based clients and other MCP clients to Firewalla via a lightweight MCP bridge, translating client requests into Firewalla API calls and returning results in a consistent, MCP-friendly format.

How to use

Launch the MCP server in either stdio or HTTP transport mode, then connect your MCP client (such as Claude Desktop, Claude Code, or an MCP-enabled editor). Start with a basic health check to confirm the server is up, then issue queries to retrieve alarms, flows, device status, and rule information. Use the HTTP transport when you need external access or multiple clients, and use stdio when you integrate with a local client or a single-process workflow.

How to install

Prerequisites you need before installing are Node.js 18+ and npm, plus a Firewalla MSP account with API access and a online Firewalla device.

# Install the MCP server globally (recommended)
npm install -g firewalla-mcp-server

# Or install locally in your project
npm install firewalla-mcp-server

Configuration and startup

Choose your transport mode and set credentials in a .env file or via environment variables when you run the server.

# Required
FIREWALLA_MSP_TOKEN=your_msp_access_token_here
FIREWALLA_MSP_ID=yourdomain.firewalla.net

# Optional - filters all queries to a specific box
FIREWALLA_BOX_ID=your_box_gid_here
```

```bash
# Build and start the MCP server (example using npm scripts if provided)
npm run build
npm run mcp:start
```

```bash
# Alternative: run with npx (production scenario)
npx firewalla-mcp-server

Transport options and how to configure them

The MCP server supports two transport modes: stdio (default) and HTTP transport.

# Stdio transport (default)
MCP_TRANSPORT=stdio

# HTTP transport (for external access)
MCP_TRANSPORT=http
MCP_HTTP_PORT=3000
MCP_HTTP_PATH=/mcp

Connect Claude Desktop or other MCP clients

If you install via npm, you can start the MCP server with the standard npx command during client setup.

npx firewalla-mcp-server
