📦 Installation

Prerequisites

🚀 Bun (v1.0.26+) - Recommended
🏠 Home Assistant instance

Option 1: Smithery.ai (Recommended for Quick Setup)

Smithery is a registry for MCP servers that makes installation incredibly easy:

# Install to Claude Desktop
npx @smithery/cli install @jango-blockchained/homeassistant-mcp --client claude

# Install to Cursor
npx @smithery/cli install @jango-blockchained/homeassistant-mcp --client cursor

# Install to VS Code
npx @smithery/cli install @jango-blockchained/homeassistant-mcp --client vscode

You'll be prompted to configure:

Home Assistant URL
Long-lived access token
Optional settings (port, debug mode)

See for detailed deployment guide.

Option 2: NPX (Quick Start)

npx @jango-blockchained/homeassistant-mcp@latest

Option 3: Bunx with GitHub (No NPM Login Required)

If you can't login to npm, use Bunx to run directly from GitHub:

# Install Bun first if you don't have it
curl -fsSL https://bun.sh/install | bash

# Then run from GitHub
bunx github:jango-blockchained/advanced-homeassistant-mcp

Alternatively, install directly from Git:

bun add git+https://github.com/jango-blockchained/advanced-homeassistant-mcp.git
homeassistant-mcp

Option 4: Docker (Containerized)

Run the MCP server in a Docker container:

# Pull the latest image
docker pull ghcr.io/jango-blockchained/advanced-homeassistant-mcp:latest

# Run with environment variables
docker run -d \
  -e HOME_ASSISTANT_URL=http://your-ha-instance:8123 \
  -e HOME_ASSISTANT_TOKEN=your_long_lived_access_token \
  -p 4000:4000 \
  --name homeassistant-mcp \
  ghcr.io/jango-blockchained/advanced-homeassistant-mcp:latest

# Or use docker-compose (see docker/ directory for examples)

Available Docker tags:

latest - Latest stable release
1.0.x - Specific version
dev - Latest development build from main branch

Option 5: Local Installation

# Install globally
bun add -g @jango-blockchained/homeassistant-mcp

# Or locally
bun add homeassistant-mcp

# Run
homeassistant-mcp

Option 6: From Source (Most Flexible)

git clone https://github.com/jango-blockchained/advanced-homeassistant-mcp.git
cd advanced-homeassistant-mcp
bun install
bun run build
bun run start:stdio
