Hi everyone,
I just published node-red-contrib-mcp (node) - Node-RED — a set of nodes that connects Node-RED to Model Context Protocol, the open standard by Anthropic for connecting AI models to external tools and data.
What it does:
7 nodes that let you build AI-powered flows with any MCP server and any OpenAI-compatible LLM:
- mcp tool — Call any MCP tool with arguments
- mcp tools — Discover available tools on an MCP server
- mcp resource — Read MCP resources
- llm call — Call any OpenAI-compatible LLM (OpenAI, Ollama, vLLM, Azure, ...)
- ai agent — Autonomous agent loop: LLM discovers tools, reasons, calls them, repeats until it has an answer
The ai agent node is the highlight — it's the same pattern as ChatGPT or Claude (tool use in a reasoning loop), but visual and auditable in Node-RED.
Quick start:
cd ~/.node-red
npm install node-red-contrib-mcp
Works with any MCP server and any OpenAI-compatible LLM including local models via Ollama.
If you want to test it with real data:
provides 91 free MCP tools for manufacturing AI (ERP, OEE, quality, warehouse).
Feedback and PRs welcome!
