MOST DANGEROUS TOOLS

High Risk

The most dangerous Home Controller tools

Execute · High device_action This tool executes commands that trigger external operations on physical smart home devices (Miele appliances). Execute · High start_multiple_zones This tool executes commands to activate physical devices (likely sauna zones based on HUUM being a sauna manufacturer). Execute · Medium start_sauna This tool executes a command that causes external hardware (HUUM sauna) to perform an action. Execute · High start_schedule This tool executes external operations on smart home devices (Miele appliances, LG ThinQ, HUUM saunas, Phyn monitors) by triggering predefined automation rules.

23 of Home Controller's 43 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Home Controller

PolicyLayer is an MCP gateway — it sits between your AI agents and Home Controller, and nothing reaches the server without passing your rules. These are the rules we recommend:

Rate limit write operations

{
  "set_away_mode": {
    "limits": [
      {
        "counter": "set_away_mode_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_activity_log": {
    "limits": [
      {
        "counter": "get_activity_log_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Each item is { zone_id, minutes, sortOrder }. Execute start_sauna Start the sauna and set target temperature (40-110°C) Execute start_schedule Manually trigger a schedule rule to run now. Execute start_zone Start watering a single zone for the given number of minutes (1–180). Execute stop_sauna Stop/turn off the sauna Execute stop_water Immediately stop any active watering on the given controller. Execute toggle_light Toggle the sauna light on/off Execute unlock_door Unlock a specific door

WRITE 11 tools

Write set_away_mode Enable or disable away mode Write set_boost_mode Enable or disable boost/party mode Write set_device_enabled Turn the controller standby on or off. When disabled, schedules will not run. Write set_fan_speed Set ventilation fan speed (0=Away, 1=Low, 2=Medium, 3=High) Write set_mode Change the water heater operation mode Write set_rain_delay Pause all schedules on the controller for the given duration (in seconds, max 604800 = 7 days). Use 0 to clear Write set_temp_profile Set temperature profile (0=Comfort, 1=Eco, 2=Warm) Write set_temp_setpoint Set temperature setpoint in °C (e.g. 21.5) Write set_temperature Set the target water temperature (95-140°F) Write set_zone_enabled Enable or disable a single zone (excludes/includes it from schedules). Write skip_schedule Skip the next occurrence of a schedule rule.

FAQ

Questions about Home Controller

How do I prevent bulk modifications through Home Controller? +

The Home Controller server has 11 write tools including set_away_mode, set_boost_mode, set_device_enabled. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach Home Controller.

How many tools does the Home Controller MCP server expose? +

43 tools across 3 categories: Execute, Read, Write. 20 are read-only. 23 can modify, create, or delete data.

How do I enforce a policy on Home Controller? +

Register the Home Controller MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every Home Controller tool call.

Deterministic rules across all 43 Home Controller tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
