Homeassistant Light Mcp

Overview

Homeassistant Light Mcp is a Model Context Protocol (MCP) server: Control Home Assistant lights and scenes. Lights only by design for safety. In practice that means any MCP-compatible AI assistant can call Homeassistant Light Mcp's tools directly — the model decides when to use them in a conversation or agent run.

It runs locally: the npm package ha-mcp-server speaks MCP over stdio on your machine. Configuration happens through environment variables — you'll need HA_URL, HA_TOKEN. The current release is v0.6.1, published under the MIT license, with source at Koneisto/HomeAssistant-Light-MCP on GitHub.

Homeassistant Light Mcp is listed under Design on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
