Home Assistant MCP Server

Content

Home Assistant MCP Server connects Claude-compatible MCP clients to Home Assistant so they can search entities, read states, call services, manage automations, inspect system information, work with dashboards, and perform supported add-on and backup operations.

The upstream project provides the ha-mcp Python package and command, a guided setup wizard, Claude Desktop and Claude Code instructions, Home Assistant OS add-on support, and transport options for local or remote deployments.

Features

• Search Home Assistant entities and read current state.
• Call Home Assistant services and control devices in bulk.
• Manage automations, scripts, helpers, scenes, groups, dashboards, areas, and zones.
• Inspect logs, history, statistics, system health, updates, and add-ons.
• Work with calendars, cameras, blueprints, HACS, energy settings, and todo lists.
• Use local command-line, Home Assistant OS add-on, Docker, HTTP, SSE, webhook proxy, or OAuth deployment paths.
• Configure and limit tools through the project's setup and settings guidance.

Installation

For MCP clients that launch stdio servers with uvx:

{
  "mcpServers": {
    "home-assistant": {
      "command": "uvx",
      "args": ["ha-mcp"],
      "env": {
        "HA_URL": "YOUR_HOME_ASSISTANT_URL",
        "HA_TOKEN": "YOUR_LONG_LIVED_ACCESS_TOKEN"
      }
    }
  }
}

Use the upstream setup wizard or Home Assistant OS add-on documentation for client-specific configuration, remote access, and transport-specific settings. Restart the MCP client after adding the server.

Use Cases

• Ask Claude what devices are currently on, unavailable, or misconfigured.
• Create or revise Home Assistant automations and scripts from natural language.
• Debug failing automations by reviewing traces, history, states, and logs.
• Add dashboard resources or update Lovelace dashboard views.
• Trigger Home Assistant services for lights, switches, climate devices, scenes, and helpers.
• Review system health, updates, backups, HACS status, and add-on state.

Safety and Privacy

Home Assistant MCP Server can be powerful because it bridges Claude to a real environment. Depending on token permissions and enabled tools, Claude may be able to change device state, alter automations, edit dashboards, inspect camera snapshots, manage add-ons, restart services, or trigger backups.

Use the narrowest Home Assistant permissions available, keep tokens out of shared configs, and do not expose remote transports to untrusted networks without appropriate authentication and TLS. Treat the MCP client as a trusted operator of your smart home.

Home Assistant data can include personal schedules, room names, presence data, security devices, camera images, logs, automation logic, and household routines. Review tool calls and model outputs before allowing destructive or sensitive operations.
