Overview

What is LIFX LAN MCP?

A Model Context Protocol (MCP) server that allows an LLM to control LIFX lights over the local area network (LAN) without cloud connectivity. It must run on the same WiFi network as the LIFX lights and targets users who want local, low‑latency smart light control through an AI assistant.

How to use LIFX LAN MCP?

Install via npx and add the provided JSON configuration to your LLM’s MCP config file (e.g., claude_desktop_config.json). The server can run in stdio mode (default, started directly by the client) or HTTP server mode (--mode sse). Tools include listing lights, getting state, setting color, turning lights on, and turning lights off – all invoked by the LLM.

FAQ from LIFX LAN MCP

What are the runtime requirements?

Node.js, TypeScript, and LIFX lights on the same local WiFi network.

Does this server require an internet connection to work?

No. It communicates with LIFX lights over the local area network and does not use cloud services.

What transport modes are available?

Stdio (default, for direct client‑server communication) and SSE (HTTP server mode, for standalone network‑accessible operation).

Is authentication supported in HTTP server mode?

No. HTTP server mode currently lacks authentication; the README warns it is dangerous and recommends use at your own risk until authentication is added.
