The MCP server for Home Assistant exposes a local Home Assistant instance to language models via the Model Context Protocol. It serves as a powerful bridge between your Home Assistant environment and LLM applications, enabling natural language control and monitoring of devices, automations, and system state. The server provides a comprehensive API to manage your entire Home Assistant ecosystem—from device control to administrative tasks—while delivering real-time updates through Server-Sent Events (SSE). With support for core device domains (lights, climate, covers, switches, sensors, media players, fans, locks, vacuums, cameras) and extended features like add-on management and HACS-based package management, users can query states, manage contexts, execute actions, and orchestrate automations. The API supports actions, batches, context queries, and state management, and is complemented by WebSocket events for streaming updates and robust error handling. Security is enforced via token-based authentication and rate limiting. The project emphasizes TypeScript type safety, thorough testing, containerized deployment with Docker, environment-driven configuration, and documentation to facilitate integration with clients such as Claude Desktop and other MCP-enabled applications.
