get_systems	List all heat-pump systems in the account
get_system	Detail view of a single system
get_device	Firmware version, connection state, serial number
get_device_points	Read any/all sensor & setting values
set_device_points	Write new values (requires Premium + WRITESYSTEM scope)
get_common_parameters	Quick view of the most useful readings
get_alarms	Active alarms / notifications
get_smart_home_zones	Smart-home climate zones

Prerequisites

• Node.js 18+
• A myUplink account with at least one connected device
• An OAuth2 application created at https://dev.myuplink.com/apps

Setup

git clone <this-repo>
cd myuplink-mcp
npm install
cp .env.example .env
# Edit .env – add your CLIENT_ID and CLIENT_SECRET
npm run build

Running the server

npm start
# or during development:
npm run dev

Claude Desktop integration

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS):

{
  "mcpServers": {
    "myuplink": {
      "command": "node",
      "args": ["/absolute/path/to/myuplink-mcp/dist/index.js"],
      "env": {
        "MYUPLINK_CLIENT_ID": "your_client_id",
        "MYUPLINK_CLIENT_SECRET": "your_client_secret",
        "MYUPLINK_REFRESH_TOKEN": "optional_saved_refresh_token"
      }
    }
  }
}

First-time authentication (Authorization Code flow)

1. Call get_authorization_url → open the URL in a browser
2. Log in and approve the scopes
3. Copy the code=… value from the redirect URL
4. Call exchange_auth_code with that code
5. From now on the server auto-refreshes tokens using the refresh token

No-browser alternative (Client Credentials)

If your myUplink application supports it, call authenticate_client_credentials – no browser needed, but only your own account data is accessible.

Common myUplink parameter IDs

Parameter	Description
40004	Outdoor temperature (BT1)
40033	Room temperature (BT50)

43005	Degree minutes
43009	Calculated flow temperature

Find more by calling get_device_points without a filter.
