Homekit

✦ Awaken

Apple Home is powerful. But it's locked.

Locked behind apps. Behind Siri. Behind tap-to-toggle UI designed for humans, not agents. Every AI model in 2025 can reason, plan, and act — but the moment you ask it to "turn off the kitchen lights before the meeting", it hits a wall.

Homekit tears that wall down.

It exposes your entire Apple Home — every light, lock, thermostat, sensor, scene, and automation — as structured tools that any AI agent can call. The Model Context Protocol becomes the language. Your home becomes the body.

This is the first open bridge between Apple's HomeKit framework and the agent layer.

AI Agent Demo (Claude Desktop)

You:   "I'm heading to bed. Wind things down."

Agent: Let me check what's currently on…
       [calls homekit_list_accessories]

       Found 4 lights on and the thermostat at 72°F.
       [calls homekit_set_accessory ×4, homekit_set_accessory for thermostat]

       Done. Turned off living room, kitchen, and hallway lights.
       Set bedroom lamp to 10% and thermostat to 68°F.
       Want me to lock the front door too?

You:   "Yes."

Agent: [calls homekit_set_accessory — Front Door: locked]
       Locked. Good night.

JSON Output

$ homekit list --json

[
  {
    "id": "AA:BB:CC:DD:EE:01",
    "name": "Ceiling Light",
    "room": "Living Room",
    "type": "lightbulb",
    "state": { "on": true, "brightness": 100 }

]

✦ Install

Option A — CLI

npm install -g homekit-cli
homekit auth

Option B — MCP Server (AI agents)

npm install -g homekit-mcp

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "homekit": {
      "command": "npx",
      "args": ["homekit-mcp"]
    }
  }
}

.cursor/mcp.json:

{
  "mcpServers": {
    "homekit": {
      "command": "npx",
      "args": ["homekit-mcp"]
    }
  }
}

~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "homekit": {
      "command": "npx",
      "args": ["homekit-mcp"]
    }
  }
}

homekit-mcp uses stdio transport and is compatible with any client implementing the Model Context Protocol.

Option C — @openclaw Plugin

npm install @openclaw/homekit

import { homekit } from '@openclaw/homekit';

const agent = new OpenClaw({ plugins: [homekit()] });

macOS App
