LIFX MCP Controller

What it does

LIFX MCP Controller brings full LIFX smart lighting control into your AI chat session. It exposes all major LIFX HTTP API operations as MCP tools, and ships with an interactive React-based MCP App UI that renders visually inside supported clients like VS Code Copilot. You can control individual bulbs or entire rooms without ever leaving chat.

Key features

• Interactive visual UI — full light control panel rendered inline in the MCP client; adjust power, brightness, colour, and effects with a click
• 9 LIFX tools — list lights, set state, toggle power, breathe/pulse effects, list & activate scenes, validate colours, stop effects
• Flexible selectors — target all lights, named groups, locations, or individual bulbs by ID or label
• Rich colour support — named colours, RGB, HSB, and Kelvin colour temperature formats
• Theme-aware UI — the embedded app adapts to the client's light/dark theme automatically
