HomeGraph MCP

Smart Home

Google's Home Graph is the state layer behind Google Home's cloud-to-cloud platform — it knows what every synced smart home device reports as its current status, and it can be told to resync. Neotask connects to HomeGraph MCP so you can ask, in plain language, what a specific device is reporting right now, or trigger a fresh sync of your whole home's device state instead of digging through a smart home app.

• Look up the reported state of a specific synced device on request
• Trigger a sync of your Home Graph data instead of waiting on the app
• Skips the manufacturer app entirely — you just ask what a device is doing

What you can automate

HomeGraph MCP

HomeGraph lets you query and sync smart home device and home state data used by Google Home's cloud-to-cloud platform. You can ask about a specific device's reported state or trigger a sync of your Home Graph data.

Real workflows

Check a device before you leave

Ask "is the thermostat reporting the state I expect" and Neotask queries HomeGraph for that device's current reported state and reads it back.

Force a resync after a change

After adding or moving a device, ask Neotask to trigger a Home Graph sync so Google Home's platform reflects the change without opening a separate app.

Frequently asked questions

What does the HomeGraph MCP connection actually do?

HomeGraph lets you query and sync smart home device and home state data used by Google Home's cloud-to-cloud platform. You can ask about a specific device's reported state or trigger a sync of your Home Graph data.

Does this control devices directly?

It reads and syncs the state that Google Home's cloud-to-cloud platform already tracks for your devices, rather than issuing its own device commands.
