npm run build

Run

# Start the MCP server, pointing at your Multiroom API
node dist/server.js --multiroom-url http://localhost:8088

Development

npm run dev -- --multiroom-url http://localhost:8088

CLI Arguments

Argument	Required	Default	Description
--multiroom-url <url>	Yes	—	Base URL of the Multiroom Audio REST API (e.g. http://localhost:8088)
--port <port>	No	3001	Port for the MCP server
