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.

Real work

What teams actually run

01

Prototyping Debugging

Quickly check if a new sensor is reporting the correct values by asking your agent for the state.

02

Smart Home Control

Manage lights, fans, and blinds through a single conversation instead of multiple apps.

03

Security Monitoring

Arm or disarm alarm panels using simple text commands.

04

Metric Analysis

Pull Prometheus metrics to analyze device performance and sensor trends.

Automate a task

Put ESPHome 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

ESPHome 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 ESPHome 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. 10 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 ESPHome, so you can see the experience inside your AI.

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

Who it's for

Built for the work ESPHome owners hand off.

This MCP is built for people working directly with ESP32 and ESP8266 hardware.

  • 01

    Home Automation Enthusiasts

    People who want to control their local environment without using standard dashboards.

  • 02

    IoT Developers

    Engineers who need to test and debug entity behaviors using natural language.

  • 03

    Hardware Engineers

    Professionals who need to monitor sensor metrics during the prototyping phase.

FAQ

Questions ESPHome owners ask.

  • 01

    How do I make my ESPHome device compatible?

    You must enable the web_server component in your ESPHome YAML configuration to allow the MCP to communicate with your device.

  • 02

    Which AI clients can I use with this MCP?

    You can use any MCP-compatible client, including Claude, Cursor, and Windsurf.

  • 03

    Do I need to host the MCP myself?

    No, Vinkius hosts and manages the MCP for you. You just connect your client and start working.

  • 04

    Can I control RGB lights?

    Yes, the light_action capability allows you to adjust brightness and RGB color values.

  • 05

    What kind of hardware does this support?

    This MCP works with any ESPHome-powered device, such as those based on ESP32 or ESP8266.

  • 06

    Can I control my lights and set specific colors using this server?

    Yes! Use the light_action capability. You can specify the entity name, the action (turn_on), and optional parameters like brightness (0-255) and RGB values (r, g, b) to get the perfect ambiance.

  • 07

    How do I check the current temperature or humidity from my sensors?

    Simply use the get_entity_state capability. Provide the domain (e.g., 'sensor') and the entity ID. The agent will return the current value and state of that specific hardware component.

  • 08

    Is it possible to trigger a physical button or restart a device?

    Yes. If you have a button entity configured in ESPHome (like a restart button), you can use the button_press capability with the entity name to trigger that action remotely.
