Hi, I’m trying to connect to Notion MCP server in order to ask question to our knowledge base but I’ don’t know how to actually connect N8N to the server.
I referred to this doc on Notion Notion MCP – Getting started – How to connect Notion to your favorite AI tools which does not provide a lot of infos.
I just created a simple workflow with an AI agent relying on MCP Client, and entered the url provided in the Notion doc. It kind of miss a part where it asks me to connect through OAuth.
I asked the Notion team but here’s their reply
Did you find a way to make it work ?
What is the error message (if any)?
Please share your workflow
