Google Home MCP is the user-facing Model Context Protocol server for live homes. It is Early Access, and it is not Home Developer MCP—the other server on Google’s MCP page, which grounds coding tools in Home API, Matter, and OpenThread docs. Home MCP exposes MCP tools so an LLM can inspect structures, monitor device states, run control actions, and analyze historical events. The consumer story still hides a developer install. Without a Google Cloud project, the Home API, and a published Web application OAuth client, Claude Cowork or OpenClaw cannot actually reach lights, cameras, or history. ## Safety limits before you connect Connecting a real home lets the agent control devices on your behalf. Home MCP enforces rate limits and safety protections, including a prohibition on sensitive actions such as unlocking doors. Behavior can still be unexpected, depending on your agent. If the home is used by other household members, inform them, or create an additional home for development and testing. You can revoke the agent’s access at any time from the Google Home app (GHA) or your My Accounts page. Core tools on the server include structure discovery with `list_homes`, resource discovery with `list_home_resources`, state monitoring with `list_home_states`, device control with `run_home_actions`, and historical analysis with `list_home_history`. ## Prerequisites - An active Google Home setup with connected devices - An active Google Home Premium Advanced subscription - Access to a Google Cloud project - An MCP-compatible AI client such as Claude Cowork, OpenClaw, or Google Antigravity ## Create a Cloud project and enable the Home API If you do not already have a project, open the Google Cloud console and create one. 1. In the console navigation menu, select **APIs & Services** > **Enabled APIs & Services**. 2. Search for **Home API** and click **Enable**. ## Configure OAuth consent and credentials Home MCP uses a user-authorized OAuth flow. Configure the consent screen: 1. Open **APIs & Services** > **OAuth consent screen**. 2. Select **External** audience, click **Get started**, and fill in the required app information and contact email. Create an OAuth client ID: 1. Open **APIs & Services** > **Credentials**. 2. Click **+ Create credentials** and select **OAuth client ID**. 3. Set **Application type** to **Web application**. 4. Add the authorized redirect URI for your client: - Claude Cowork: `https://claude.ai/api/mcp/auth_callback` - OpenClaw: the redirect URI specified by your local OpenClaw installation - Google Antigravity: `https://antigravity.google/oauth-callback` 5. Click **Create** and copy the **Client ID** and **Client Secret** to a secure location. Publish the application: 1. Open **Google Auth Platform** > **Audience**. 2. Under **Publishing status**, click **Publish app**. ## Connect Claude Cowork 1. Open Claude Connectors. 2. Click **+** and select **Add custom connector**. 3. Enter the server URL `https://home.googleapis.com/mcp`. 4. Click **Advanced settings** and enter your **Client ID** and **Client Secret**. 5. Click **Add** and complete the OAuth authorization flow in your browser. 6. In a Cowork chat, click **+** in the lower-left corner, select **Connectors**, and toggle **home_mcp** on. ## Connect OpenClaw Configure OpenClaw for remote SSE transport with OAuth. Prepare this configuration patch JSON block, replacing the placeholders with your Client ID, Client Secret, and local redirect URL: ``` { "mcp": { "servers": { "home_mcp": { "url": "https://home.googleapis.com/mcp", "transport": "sse", "auth": "oauth", "oauth": { "scope": "https://www.googleapis.com/auth/home.platform.v2", "redirectUrl": "[YOUR_OPENCLAW_REDIRECT_URL]" }, "env": { "CLIENT_ID": "YOUR_CLIENT_ID", "CLIENT_SECRET": "YOUR_CLIENT_SECRET" } } } } } ``` Apply the configuration patch in your terminal: ``` openclaw config patch --stdin ``` Restart the OpenClaw gateway: ``` openclaw gateway restart ``` Initiate the authentication flow: ``` openclaw mcp login home_mcp ``` Follow the generated authorization URL to sign in and grant access. ## Optional: chat-driven setup and familiar faces If your assistant can manage MCP tool configuration from chat, the Home MCP docs include this prompt. It names a different server URL than the Claude Cowork and OpenClaw manual steps. Use the prompt and URL exactly as shown for the path you are following, with your credentials substituted: ``` Please configure the Home MCP server for me with these settings: - Name: home_mcp - Server URL: https://preprod-home.sandbox.googleapis.com/mcp - Transport: sse - OAuth Scope: https://www.googleapis.com/auth/home.platform.v2 - Client ID: YOUR_CLIENT_ID - Client Secret: YOUR_CLIENT_SECRET ``` Familiar faces data requires a separate consent. The granter must be a manager of the structure. The structure must have at least one compatible Google Nest camera or doorbell and an active Google Home Premium subscription with **Familiar face detection** enabled for each camera or doorbell. With your OAuth 2.0 Client ID and structure ID (UUID), visit: ``` https://home.google.com/connections/feature_consent?client_id=CLIENT_ID&structure_id=STRUCTURE_ID&features=1&continue=https%3A%2F%2Fhome.google.com ``` If the agent is already connected, you can ask it for the structure ID, then open that link and provide consent. ## Verify connection and functionality 1. Launch your AI assistant or workspace session. 2. Check active MCP server connections and confirm that `home_mcp` is listed with active tools. 3. Issue sample prompts: - Entity discovery: `How many lights do I have in my house?` - Real-time state monitoring: `Is my home secured?` - Device control: `Turn off all the outside lights.` - Historical event analysis: `What happened while I was out?` 4. Grant tool execution permissions when prompted. The assistant can retrieve real-time state data, and responses are grounded in your home telemetry. Creating and managing automations with Home MCP is not supported at this time. Some traits are marked experimental and may not work as expected. You may also see longer-than-expected latency. Work through the Cloud project, Home API, and OAuth client on Google’s Home MCP documentation, then add `https://home.googleapis.com/mcp` in Claude Cowork or patch OpenClaw, restart the gateway, and complete login. After you authenticate, run the four verify prompts and confirm you know how to revoke access in the Google Home app. ## Sources - [Google Home MCP Server](https://developers.home.google.com/mcp/home) - [MCP Servers](https://developers.home.google.com/mcp)
