MCP Server for Bosch Home Connect

This MCP (Model Context Protocol) server provides integration with the Bosch Home Connect API, allowing you to control and monitor your Bosch/Siemens smart home appliances.

Features

• List all connected appliances
• Get appliance status and settings
• View available programs
• Start and stop programs
• Update appliance settings
• OAuth authentication support

Prerequisites

1. A Home Connect developer account
2. Registered application with Home Connect API
3. Node.js 22+ installed

Development checks

Run npm test to build and exercise MCP initialization, all eight tool contracts, tool dispatch and error propagation. The tests replace the HTTP client adapter; they require no Home Connect credentials and never contact appliances or the API. Run npm audit to inspect the resolved dependency tree.

GitHub CI runs these offline tests on Node.js 22 and 24 and checks the lockfile for moderate or higher audit findings. No Home Connect secrets are required.

The SDK update requires Node.js 22 or newer for this project. Users on older Node.js versions must upgrade their runtime before installing it.

The server uses stdio transport. The SDK advisory GHSA-w48q-cv73-mx4w affects HTTP-based transports, not this server's stdio transport. The SDK update removes the affected dependency version without changing the eight public tools.

Setup

1. Register for Home Connect API

1. Go to Home Connect Developer Portal
2. Create an account and register a new application
3. Note down your Client ID and Client Secret

2. Installation

# Clone the repository
git clone https://github.com/nikolausm/mcp-server-home-connect.git
cd mcp-server-home-connect

# Install dependencies
npm install

# Build the project
npm run build

3. Configuration

Create a .env file in the project root:

HOME_CONNECT_CLIENT_ID=your_client_id
HOME_CONNECT_CLIENT_SECRET=your_client_secret
HOME_CONNECT_REDIRECT_URI=http://localhost:3000/callback
HOME_CONNECT_ACCESS_TOKEN=your_access_token
HOME_CONNECT_REFRESH_TOKEN=your_refresh_token

4. Getting Access Tokens

You'll need to complete the OAuth flow to get access tokens:

1. Use the get_auth_url tool to get the authorization URL
2. Visit the URL and authorize the application
3. You'll receive an authorization code
4. Exchange the code for access and refresh tokens using the Home Connect API

Usage with Claude Desktop

      "command": "node",
      "args": ["/path/to/mcp-server-home-connect/build/index.js"],
      "env": {
        "HOME_CONNECT_CLIENT_ID": "your_client_id",
        "HOME_CONNECT_CLIENT_SECRET": "your_client_secret",
        "HOME_CONNECT_ACCESS_TOKEN": "your_access_token",
        "HOME_CONNECT_REFRESH_TOKEN": "your_refresh_token"
      }
    }
  }
}

Example Usage

// Get all appliances
await use_mcp_tool("home-connect", "get_appliances", {});

// Get status of a specific appliance
await use_mcp_tool("home-connect", "get_appliance_status", {
  haId: "BOSCH-HCS06COM1-0123456789AB"
});

// Start a dishwasher program
await use_mcp_tool("home-connect", "start_program", {
  haId: "BOSCH-HCS06COM1-0123456789AB",
  programKey: "Dishcare.Dishwasher.Program.Auto2",
  options: {
    "BSH.Common.Option.StartInRelative": 3600 // Start in 1 hour
  }
});

Troubleshooting

Authentication Issues

• Ensure your access token is valid
• The server automatically refreshes tokens when they expire
• Check that your Client ID and Secret are correct

Connection Issues

• Verify your appliances are connected to Home Connect
• Check your internet connection
• Ensure the appliances are in remote control mode

Remote Start Issues (400 Error)

Known Limitation: Some Bosch/Siemens appliances require the first program start after power-on to be done manually at the device for security reasons.

Symptoms:

• API returns 400 error when trying to start a program
• All status checks show the device is ready (RemoteControlActive: true, PowerState: On)
• Manual start at the device works fine

Workaround:

1. Start the program manually at the device once
2. After manual start, the API can monitor progress, stop programs, and change settings
3. Subsequent remote starts may work (device-dependent)

Affected Devices:

• Confirmed on Bosch Dishwashers (SMV series)
• May affect other appliance types

This is a security feature by Bosch/Siemens and not a bug in the MCP server.
