🚀 Quick Start

Installation via npm (Recommended)

Install globally to use with any MCP client:

npm install -g plugwise-mcp-server

Or use directly with npx (no installation needed):

npx plugwise-mcp-server

Installation from Source

git clone https://github.com/Tommertom/plugwise-mcp-server.git
cd plugwise-mcp-server
npm install
npm run build

Prerequisites

• Node.js 17 or higher
• npm or yarn
• Plugwise gateway (Adam, Anna, Smile P1, or Stretch)

Quick Test

Test the installation without real hardware using mock mode:

# Test all read operations
npm run test:read-only -- --mock

# Test protocol features
npm run test:features -- --mock

Or with real hardware:

# Set up gateway credentials
echo "PLUGWISE_HOST=192.168.1.100" > .env
echo "PLUGWISE_PASSWORD=your-gateway-password" >> .env

# Run tests
npm run test:read-only

See Quick Test Guide for more options.

Start the Server

Option 1: Standard MCP Server (15+ specialized tools)

When installed via npm:

plugwise-mcp-server

When running from source:

npm start

Option 2: AI Agent Mode (Single natural language tool)

# Interactive mode with prompt
npm run agent "List my devices"
npm run agent "Set living room to 21 degrees"

# Interactive with verbose debugging
npm run agent "What's the power usage?" -- -v

# MCP server mode (no arguments)
npm run agent

# JSON-RPC mode (for scripting)
npm run agent -- --jsonrpc
echo '{"jsonrpc":"2.0","method":"execute","params":{"instruction":"List devices"},"id":1}' | npm run agent -- --jsonrpc

See Agent Documentation and JSON-RPC Mode for details.

🔌 Adding the MCP Server to Your Client

The Plugwise MCP server can work with any MCP client that supports standard I/O (stdio) as the transport medium. Choose between:

• Standard Mode: 15+ specialized tools for direct device control
• Agent Mode: Single manage_plugwise tool with natural language interface

Claude Desktop

  }
}

Cline

To configure Cline to use the Plugwise MCP server, edit the cline_mcp_settings.json file. You can open or create this file by clicking the MCP Servers icon at the top of the Cline pane, then clicking the Configure MCP Servers button.

{
  "mcpServers": {
    "plugwise": {
      "command": "npx",
      "args": ["-y", "plugwise-mcp-server@latest"],
      "disabled": false,
      "env": {
        "HUB1": "abc12345",
        "HUB1IP": "192.168.1.100",
        "HUB2": "def67890",
        "HUB2IP": "192.168.1.101"
      }
    }
  }
}

Cursor

To configure Cursor to use the Plugwise MCP server, edit either the file .cursor/mcp.json (to configure only a specific project) or the file ~/.cursor/mcp.json (to make the MCP server available in all projects):

{
  "mcpServers": {
    "plugwise": {
      "command": "npx",
      "args": ["-y", "plugwise-mcp-server@latest"],
      "env": {
        "HUB1": "abc12345",
        "HUB1IP": "192.168.1.100",
        "HUB2": "def67890",
        "HUB2IP": "192.168.1.101"
      }
    }
  }
}

Visual Studio Code Copilot

To configure a single project, edit the .vscode/mcp.json file in your workspace:

{
  "servers": {
    "plugwise": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "plugwise-mcp-server@latest"],
      "env": {
        "HUB1": "abc12345",
        "HUB1IP": "192.168.1.100",
        "HUB2": "def67890",
        "HUB2IP": "192.168.1.101"
      }
    }
  }
}

To make the server available in every project you open, edit your user settings:

{
  "mcp": {
    "servers": {
      "plugwise": {
        "type": "stdio",
        "command": "npx",
        "args": ["-y", "plugwise-mcp-server@latest"],
        "env": {
          "HUB1": "abc12345",
          "HUB1IP": "192.168.1.100",
          "HUB2": "def67890",
          "HUB2IP": "192.168.1.101"
        }
      }
    }
  }
}

Windsurf Editor

To configure Windsurf Editor, edit the file ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "plugwise": {
      "command": "npx",
      "args": ["-y", "plugwise-mcp-server@latest"],
      "env": {
        "HUB1": "abc12345",
        "HUB1IP": "192.168.1.100",
        "HUB2": "def67890",
        "HUB2IP": "192.168.1.101"
      }
    }
  }
}

Environment Variables

The server reads hub passwords from environment variables. You can provide these in two ways:

Option 1: MCP Configuration (Recommended) Add the env field directly to your MCP client configuration as shown in the examples above.

Option 2: .env File Create a .env file in your project root or set system-wide environment variables:

# Hub passwords (8-character codes from gateway stickers)
HUB1=abc12345
HUB2=def67890

# Optional: Known IP addresses for faster discovery and auto-loading
HUB1IP=192.168.1.100
HUB2IP=192.168.1.101

Security Note: When using the MCP configuration env field, credentials are passed securely to the server process. For enhanced security, consider using .env files which are typically excluded from version control.
