Homeassistant Light Mcp

A focused Home Assistant integration that deliberately limits scope to lights only for safety reasons. It exposes eight tools including scene_show_lights for viewing RGB colors and brightness, scene_adjust_light for controlling individual lights, and full scene management (create, activate, update, delete). Also includes scene_blackout to kill all lights with optional exclusions. The key differentiator is detailed color information that the official Home Assistant MCP doesn't expose, plus built-in workarounds for IKEA Tradfri timing issues when switching between RGB and Kelvin modes. Scenes are backed up locally to ~/.config/ha-mcp-server and support both exclusive and additive modes. Connects via Home Assistant's REST API using a long-lived access token.
