I've been having some fun with Claude and my home automation setup, as mentioned here. I realised that there might be some value to a more generic AI -> Node-RED connection, not directly related to home automation specifically, so I created @frtnbach/node-red-contrib-mcp-server.
It's a generic building block for turning Node-RED flows into MCP server tools: expose any flow as an MCP tool behind an OAuth-protected endpoint, with optional Node-RED admin (flow read/deploy) tools. No home automation or other domain coupling — this is a bare-bones way to let AI assistants (Claude, etc.) call your flows as tools.
I've included a few examples to show how it's done: Jellyfin, Calibre, Docker (be careful with this one), Music Assistant, Radarr, iRobot/rest980, Overseerr, Sonarr and Spotify. Not all of them are necessarily useful, but the fun part is playing around and seeing what sticks, right?
