Smartrent

PyPI version Python versions License: MIT

An MCP (Model Context Protocol) server that lets Claude control your SmartRent smart home devices — locks, thermostat, light switches, and sensors — through natural conversation.

You: "Turn off the kitchen lights and lock the front door"
Claude: "Kitchen turned off. Front Door - Lock is now locked."

Requirements

• A SmartRent account with devices already set up in the SmartRent app (this only works if your building/home uses SmartRent hardware — front door locks, thermostats, switches, or sensors)
• Python 3.10+
• Either uv or pip — you likely already have one of these

---

Installation

Option A — using uv (recommended, no separate install step)

If you don't have uv yet, install it once:

# Mac/Linux
curl -LsSf https://astral.sh/uv/install.sh | sh

# Windows (PowerShell)
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

That's it — uvx will download and run the package automatically the first time Claude needs it. No manual install command required.

Option B — using plain pip

pip install smartrent-mcp

---

Setup — Claude Desktop

1. Open your Claude Desktop config file

• Mac: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

2. Add the server entry

If you installed via uv (Option A):

{
  "mcpServers": {
    "smartrent-mcp": {
      "command": "uvx",
      "args": ["smartrent-mcp"],
      "env": {
        "SMARTRENT_EMAIL": "your_smartrent_email",
        "SMARTRENT_PASSWORD": "your_smartrent_password"
      }
    }
  }
}

If you installed via pip (Option B):

{
  "mcpServers": {
    "smartrent-mcp": {
      "command": "smartrent-mcp",
      "env": {
        "SMARTRENT_EMAIL": "your_smartrent_email",
        "SMARTRENT_PASSWORD": "your_smartrent_password"
      }
    }
  }
}

If you already have other servers under "mcpServers", just add "smartrent-mcp" as another entry — don't replace the existing ones.

3. Restart Claude Desktop

Fully quit the app (Cmd+Q on Mac, or right-click the tray icon and Quit on Windows) and reopen it. Closing the window alone is not enough.

4. Try it

Ask Claude:

• "What's the status of my home?"
• "Turn on the kitchen lights"
• "Lock the front door"
• "Set temperature to 72 cool mode"

---

Setup — Claude Web

Claude Web only connects to remote MCP servers over a URL — it cannot run local commands like uvx. To use this server with Claude Web, you need to self-host a remote instance. See Self-Hosting below, then add your deployed URL in Claude Web → Settings → MCP Servers.

---

Available Tools

Tool	Description	Parameters
ping	Test that the server is alive	none
get_device_status	Read the status of all devices — locks, thermostat, switches, sensors	none
switch_control	Turn a light switch on or off	name (e.g. "kitchen"), action ("on" / "off")
lock_door	Lock or unlock the front door	action ("lock" / "unlock")
set_temperature	Set thermostat temperature, mode, and unit	temperature (int), mode ("cool" / "heat" / "auto" / "off", default "cool"), unit ("F" / "C", default "F")

Device matching is partial and case-insensitive — "dining" will match a switch named "Dining Room".

---

Self-Hosting (Remote / SSE mode)

By default this package runs in stdio mode for local use with Claude Desktop. To run it as a remote, always-on server (for Claude Web or shared use), set the TRANSPORT environment variable:

TRANSPORT=sse [email protected] SMARTRENT_PASSWORD=yourpassword smartrent-mcp

This starts an HTTP/SSE server (default port 8000, override with PORT). Deploy it anywhere that runs Python — Railway, Render, Fly.io, etc. — with these environment variables set:

Variable	Required	Description
SMARTRENT_EMAIL	Yes	Your SmartRent account email
SMARTRENT_PASSWORD	Yes	Your SmartRent account password
TRANSPORT	No	stdio (default) or sse
PORT	No	Port to listen on in sse mode (default 8000)

Once deployed, connect to it at https://your-deployment-url/sse.

---

Troubleshooting

"Invalid Host header" or connection refused on a remote deployment The server disables DNS rebinding protection by default to support remote access. If you've changed this, make sure TransportSecuritySettings(enable_dns_rebinding_protection=False) is set in server.py.

Claude Desktop doesn't show any tools Make sure you fully quit and restarted the app (not just closed the window). Check the MCP logs:

• Mac: ~/Library/Logs/Claude/mcp-server-smartrent-mcp.log
• Windows: %APPDATA%\Claude\logs\mcp-server-smartrent-mcp.log

"Username or password was wrong" Verify your SmartRent credentials work by logging into the SmartRent mobile app with the same email/password.

"No switch/lock/thermostat found on this account" Your SmartRent account needs the corresponding device type already set up in the SmartRent app.

---

Security

Your SmartRent credentials are passed as environment variables directly to the server process and are never sent anywhere except SmartRent's own login API. They are not logged or stored by this package.

If you're self-hosting in sse mode, anyone with your server's URL can control your home — there is currently no authentication layer on remote mode. Keep your deployment URL private, or restrict network access to it.
