Enhanced Home Assistant MCP

License: MIT TypeScript Home Assistant

A comprehensive MCP (Model Context Protocol) server that provides extensive integration with Home Assistant, enabling AI assistants to interact with smart home devices, automations, and system management.

🚀 Quick Start with NPX

No installation required! Run directly with npx:

# Set your Home Assistant credentials export HOMEASSISTANT_URL="http://your-ha-ip:8123" export HOMEASSISTANT_TOKEN="your-long-lived-access-token" # Start the server npx @thelord/enhanced-homeassistant-mcp

Prerequisites

Node.js 18+
Home Assistant instance with API access
Long-lived access token from Home Assistant

Installation

# Clone the repository git clone https://github.com/gilberth/enhanced-homeassistant-mcp.git cd enhanced-homeassistant-mcp # Install dependencies npm install # Copy environment template cp .env.example .env

Configuration

Edit the .env file with your Home Assistant details:

HOME_ASSISTANT_URL=http://homeassistant.local:8123 HOME_ASSISTANT_TOKEN=your_long_lived_access_token_here DEBUG=false REQUEST_TIMEOUT=10000

Getting Your Access Token

Open Home Assistant in your browser
Go to your Profile (click on your username in the sidebar)
Scroll down to "Long-Lived Access Tokens"
Click "Create Token"
Give it a name and copy the generated token

Running the Server

Option 1: NPX (Recommended - No installation)

# Quick start npx @thelord/enhanced-homeassistant-mcp # With options npx @thelord/enhanced-homeassistant-mcp --debug start npx @thelord/enhanced-homeassistant-mcp inspect npx @thelord/enhanced-homeassistant-mcp health

Option 2: Local Installation

# Development mode npm run dev # Production mode npm run build npm start # With MCP Inspector (for testing) npm run inspector

🐳 Docker Deployment (Recomendado)

Para un despliegue fácil y seguro usando Docker:

# Construir la imagen docker build -t enhanced-homeassistant-mcp . # Ejecutar el contenedor docker run -d \ --name homeassistant-mcp \ --restart unless-stopped \ -e HOME_ASSISTANT_URL="http://your-hass-ip:8123" \ -e HOME_ASSISTANT_TOKEN="your_long_lived_token" \ enhanced-homeassistant-mcp

🚑 Troubleshooting

Common Issues

Connection Failed

Verify HOME_ASSISTANT_URL is correct and accessible
Check that Home Assistant is running
Ensure no firewall blocking the connection

Authentication Failed

Verify your long-lived access token is correct
Check token hasn't expired or been revoked
Ensure token has necessary permissions

Entity Not Found

Use homeassistant_list_all_entities to find correct entity IDs
Check entity exists and is enabled in Home Assistant
Verify correct domain prefix (e.g., light., sensor.)

Service Call Failed

Use homeassistant_list_services to verify service availability
Check service parameters are correct for your device
Some services require specific entity types or states
