Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Automate a task

Put Home Assistant to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

Home Assistant works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put Home Assistant to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Connect your client

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 15 capabilities arrive ready to run.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Home Assistant, so you can see the experience inside your AI.

It does not authenticate your account with Home Assistant. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

  • 01

    Smart Home Enthusiasts

    People who want to control their entire device ecosystem through a single AI interface.

  • 02

    Home Automation Builders

    Users who want to integrate their existing HA automations into broader AI-driven workflows.

    Property Managers

    Professionals who need to monitor and control devices across multiple different properties.

FAQ

Questions Home Assistant owners ask.

  • 01

    Does this work with local Home Assistant installs?

    Yes. You can connect to a local instance using your local IP address or via Nabu Casa cloud.

  • 02

    What do I need to connect this MCP?

    You will need your Home Assistant URL and a Long-Lived Access Token generated from your Home Assistant profile.

  • 03

    Can I control any device in my house?

    If the device is integrated into Home Assistant and has an associated entity, your agent can control it using service calls.

  • 04

    How does the AI know which lights I have?

    The agent uses the list_entity_states capability to discover all available devices and their current statuses.

  • 05

    Is my data secure?

    The MCP uses your provided Long-Lived Access Token to communicate with your instance, following standard Home Assistant security protocols.

  • 06

    What Home Assistant URL should I use?

    For local instances, use your Home Assistant's local network URL: http://YOUR_IP:8123 (or http://homeassistant.local:8123). For cloud access via Nabu Casa, use your remote URL: https://YOUR_INSTANCE.ui.nabu.casa. The API is accessible at the same base URL as your Home Assistant frontend.

  • 07

    How do I get a Long-Lived Access Token?

    Log in to your Home Assistant web interface, go to your user profile (click your name in the sidebar, then Profile), scroll down to Long-Lived Access Tokens, click Create Token, give it a name (e.g., 'MCP Server'), and copy the generated token. This token never expires unless manually revoked.

  • 08

    What devices and integrations are supported?

    All Home Assistant integrations are supported since the API works at the service/state level. This includes lights (Philips Hue, LIFX, etc.), thermostats (Nest, Ecobee, etc.), covers/blinds, switches, media players (Sonos, Chromecast, etc.), sensors, cameras, locks, vacuums, and 1000+ other integrations. Use list_entity_states to discover all available entities.

  • 09

    Can I trigger Home Assistant automations from the API?

    Yes! You can trigger automations in multiple ways: 1) Call the automation.trigger service directly, 2) Fire a custom event using fire_ha_event that matches an event trigger in your automation, 3) Call the script.turn_on service to run scripts. You can also control devices directly which will trigger related automations.
