Problems using MCP Servers within a workflow

Describe the problem/error/question

I have been trying to learn how to use MCP servers within an N8N workflow to distribute tasks to an agent. I was having problems so I decided to use a template and see how that worked, but even in the template I am getting the same error. The template in question is Here. I have also looked for youtube videos and don’t see what I am doing differently or why it isn’t working. I feel like I must be missing something very silly.

What is the error message (if any)?

Error: The resource you are requesting could not be found Details: Not Found

Please share your workflow

I’m sorry, I wasn’t able to retrieve the events for 2025-12-16. The resource could not be found.

Information on your n8n setup

  • n8n version: 2.02
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main): default
  • Running n8n via (Docker, npm, n8n cloud, desktop app): n8n cloud

I’m having the same problem too.
