Description

This project provides a secure, extensible MCP server that bridges AI assistants (Claude, GPT, Cursor, etc.) with Home Assistant to manage lights, climate, automations, notifications, and device discovery. It supports multiple transports (HTTP, WebSocket, stdio), JWT authentication, rate limiting, input sanitization, and streaming responses, and is built for high performance on the Bun runtime. The server includes voice features (Whisper), wake-word detection, and a modular plugin-like tool system for easy extension and integration.
