Cloud agent can't use Notion MCP

[Mark_Tasnadi (Márk Tasnádi)]

Where does the bug appear (feature/product)?

Background Agent (GitHub, Slack, Web, Linear)

Describe the Bug

Unfortunately, I wasn’t able to retrieve the content of that Notion page. Here’s why:

Notion MCP server needs authentication — the Notion integration isn’t connected yet, so I can’t use the Notion API to read pages.
Direct URL fetch returned no content — Notion pages require authentication and don’t expose their content to unauthenticated requests.
To fix this, please authenticate the Notion MCP server in the Cursor Desktop IDE (Settings > MCP Servers > Notion), then retry. Once authenticated, I’ll be able to read the full page content using the Notion API.

Steps to Reproduce

I have notion connected in plugins, and when I tag @cursor in slack and I have a notion link in the message, it tries to fetch it and it says I have to authenticate it, but it is already authenticated

Expected Behavior

the background agent should be able to fetch the notion doc

Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

Hey @Mark_Tasnadi!

It sounds like it might be authenticated in Cursor the IDE, but not for the Cloud Agent. Could you try authenticating the MCP server from https://cursor.com/agents? Do you see it turned on, with a green dot?

I’ve just given it a try with an @cursor command from Slack to use the MCP server and it’s working!
