🌦️ Weather Forecast Agent with MCP + n8n (Live Server + One-Click Workflow)

Want to see a live MCP weather tool working inside the new n8n Agent node?

I built a full demo workflow that lets you ask for current or 5-day weather forecasts using a hosted MCP server. It uses OpenWeatherMap behind the scenes — but no API key is required to use the weather tool.

Everything is preconfigured. Just paste the JSON below, plug in your OpenAI key, and go.
