Node-RED MCP

What is Node-RED MCP?

Node-RED MCP connects AI assistants to Node-RED, the popular flow-based programming tool for IoT and automation. Built on Node.js, Node-RED provides a visual editor for wiring together devices, APIs, and services.

Flow Generation

Describe the automation workflow you need, and Node-RED MCP can generate the flow JSON with properly configured nodes, connections, and settings. AI models understand Node-RED's node types and wiring conventions.

Configuration
