Honeywell Home MCP Server

arm_system

Choose the arming mode: "stay" (arms perimeter sensors like doors and windows but ignores interior motion detectors, ideal when occupants are home) or "away" (arms all sensors including interior motion, ideal when the property is empty). After arming, verify the new state with get_security_status. Arm the Honeywell Home security system

disarm_system

Use this when returning home or when authorized personnel need access. After disarming, verify the new state with get_security_status. Disarm the Honeywell Home security system

get_air_quality

Returns data such as PM2.5 particulate levels, VOC (volatile organic compounds) index, CO2 concentration, humidity, and overall air quality rating. Use this to assess whether ventilation or air purification is needed. Get air quality readings from a Honeywell Home device

get_camera_snapshot

The returned data includes an image URL or base64-encoded snapshot. This is useful for a quick visual check of a room or area without streaming live video. Provide the camera device_id from get_devices. Capture a snapshot image from a Honeywell Home camera

get_camera_status

Use the device_id obtained from get_devices. Useful for quickly verifying that a security camera is active and functioning before reviewing footage. Get the status of a Honeywell Home camera

get_devices

Provide a locationId obtained from the get_locations tool. If no locationId is supplied, returns all devices across all locations. Useful for inventorying connected hardware. List all devices at a Honeywell Home location

get_locations

) associated with the authenticated Honeywell Home account. Each location contains metadata such as name, address, timezone, and the list of devices registered at that address. Use this tool first to discover location IDs before querying devices or security systems. List all registered Honeywell Home locations

get_security_status

Returns whether the system is armed (stay or away mode), disarmed, or in alarm, along with the status of connected sensors (doors, windows, motion detectors). Provide a location_id from get_locations. Get the current status of the Honeywell Home security system

get_thermostat_data

Use this to check what temperature the thermostat is targeting and whether the HVAC system is actively running. Get detailed thermostat readings and configuration

update_setpoint

You can adjust the heat setpoint (minimum temperature), the cool setpoint (maximum temperature), or switch the operating mode (heat, cool, auto, off). Only send the parameters you want to change. After modifying setpoints, verify the change with get_thermostat_data. Use this to help users regulate heating and cooling remotely. Adjust the temperature setpoint on a Honeywell thermostat
