The hass-mcp-server is a custom component designed for Home Assistant, providing an MCP (Model Context Protocol) server that utilizes HTTP transport for AI integration. This allows AI assistants, such as Claude, to interact seamlessly with Home Assistant. It supports OAuth 2.0 for secure authentication and offers an alternative Long-Lived Access Token method for local setups. The server grants full access to Home Assistant's API, facilitating extensive management of entities, services, and configurations.

Key features include easy installation via HACS, CRUD management for automations and scenes, and comprehensive YAML file handling with automatic backups. System administration tools are also included for monitoring and maintaining optimal performance. The integration supports both OAuth and Long-Lived Access Tokens simultaneously, ensuring flexibility for various client setups while providing rich AI interaction capabilities through resources, prompts, and completions.
