About Google Home MCP Server
Connect to Google Nest devices via the Smart Device Management (SDM) API and control your smart home from any AI agent. Manage thermostats, view camera feeds, and interact with doorbells.
LlamaIndex agents combine Google Home tool responses with indexed documents for comprehensive, grounded answers. Connect 12 tools through Vinkius and query live data alongside vector stores and SQL databases in a single turn. ideal for hybrid search, data enrichment, and analytical workflows.
What you can do
- List Devices — See all your Nest thermostats, cameras, doorbells, and displays
- Thermostat Control — Set mode (Heat/Cool/Off), adjust temperatures, enable eco mode, and control fan timer
- Camera Streaming — Generate live RTSP or WebRTC stream URLs from Nest cameras and doorbells
- Doorbell Management — View doorbell camera feeds and stream events
- Structure & Rooms — Browse your home's structures and room organization
- Device Details — Get full device state including all traits and current settings
The Google Home MCP Server exposes 12 tools through the Vinkius. Connect it to LlamaIndex in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

Why Use LlamaIndex with the Google Home MCP Server
LlamaIndex provides unique advantages when paired with Google Home through the Model Context Protocol.
Data-first architecture: LlamaIndex agents combine Google Home tool responses with indexed documents for comprehensive, grounded answers
Query pipeline framework lets you chain Google Home tool calls with transformations, filters, and re-rankers in a typed pipeline
Multi-source reasoning: agents can query Google Home, a vector store, and a SQL database in a single turn and synthesize results
Observability integrations show exactly what Google Home tools were called, what data was returned, and how it influenced the final answer
Google Home + LlamaIndex Use Cases
Practical scenarios where LlamaIndex combined with the Google Home MCP Server delivers measurable value.
Hybrid search: combine Google Home real-time data with embedded document indexes for answers that are both current and comprehensive
Data enrichment: query Google Home to augment indexed data with live information before generating user-facing responses
Knowledge base agents: build agents that maintain and update knowledge bases by periodically querying Google Home for fresh data
Analytical workflows: chain Google Home queries with LlamaIndex's data connectors to build multi-source analytical reports
Google Home MCP Tools for LlamaIndex (12)
These 12 tools become available when you connect Google Home to LlamaIndex via MCP:
generate_camera_stream
The stream token is temporary and should be used immediately. Stop the stream when done. Generate a live camera stream URL from a Nest camera or doorbell
get_device
Use device ID from list_devices or device name. Get details for a specific Google Nest device
list_devices
Shows device types, traits, and room assignments. USE WHEN: - User wants to see all their Nest devices - User needs to find device IDs for other commands - User is exploring their smart home setup - User asks "what Nest devices do I have" EXAMPLES: - "List all my Nest devices" → call with no params - "Show my smart home devices" → call with no params - "What Nest devices are connected?" → call with no params List all Google Nest devices in your home
list_rooms
Useful for understanding device locations and room organization. List all rooms in a specific structure
list_structures
Each structure contains rooms and devices. List all structures (homes) in your Google Nest account
set_fan_timer
Turns the fan on for a specified duration. Duration is optional and defaults to the thermostat setting. Set the fan timer on a Nest thermostat
set_thermostat_cool
Use this when the thermostat is in COOL or HEATCOOL mode. Set the cooling temperature on a Nest thermostat
set_thermostat_eco
This is a manual override of the eco/eco-friendly temperature settings. Set Nest thermostat to eco mode for energy savings
set_thermostat_heat
Use this when the thermostat is in HEAT or HEATCOOL mode. Set the heating temperature on a Nest thermostat
set_thermostat_mode
Supported modes: HEAT, COOL, HEATCOOL, OFF. Use device ID from list_devices to target a specific thermostat. USE WHEN: - User wants to change thermostat mode - User asks to turn heating/cooling on or off - User wants to switch thermostat operating mode - User says "set thermostat to heat/cool/off" PARAMETERS: - device_id (REQUIRED): Thermostat device ID - mode (REQUIRED): One of HEAT, COOL, HEATCOOL, or OFF EXAMPLES: - "Set thermostat to heat mode" → call with device_id, mode="HEAT" - "Turn off the thermostat" → call with device_id, mode="OFF" - "Set thermostat to cool" → call with device_id, mode="COOL" Set the mode of a Nest thermostat
set_thermostat_range
Useful for HEATCOOL mode to define the comfort range. Set both heating and cooling temperatures on a Nest thermostat
stop_camera_stream
Use the stream token returned from generate_camera_stream to properly terminate the stream session. Stop an active camera stream from a Nest camera or doorbell
Example Prompts for Google Home in LlamaIndex
Ready-to-use prompts you can give your LlamaIndex agent to start working with Google Home immediately.
"List all my Nest devices and show me what thermostats I have."
"Set my living room thermostat to 22°C heating mode."
"Show me the live feed from my front door camera."
