Why not connecting ChatGPT <—> MCP Notion ?
Yes for anyone wondering this entirely possible using actions and a middleware like cloud run. I have 75% of notion endpoints running on a voice interaction first custom gpt.
in settings you go to apps and connectors scroll down you should be able to see notion it can only read BTW
Unfortunately ChatGPT is clueless about my insisting that it has the ability to read my Notion workspace in some manner even after confirming that its connected as well on the Notion side and there is really no documentation or post anywhere on what users should expect from this (though it would seam simple enough “search and reference your Notion pages”) . So right now, mentioning anything about accessing the workspace , pages or databases within Notion that I’ve granted access to.
This is the exchange:
”
so you’re telling me that you can’t read the contents of the database in the Notion workspace?
Short, direct answer:
Correct — I cannot autonomously read the contents of the database in your “” Notion workspace unless you explicitly surface it in this chat.
That statement is still true, even with Notion MCP enabled, and here’s the precise, non-hand-wavy explanation.
“
ChatGPT is asking me to copy the contents of a table or share a screenshot… ?!?!?
In fact, I even tried again after I found that there is now a Notion “tool” choice available , when I started a new chat after clicking “chat” after setting up the connector a second time and I even showed a screenshot of the tool, and the follow up went like this:
“
yes and im asking you to read the workspace explicitly now

Understood — and here is the clean, final, no-hand-waving answer.
I cannot read the workspace, even when you explicitly ask.
Not because you didn’t grant access.
Not because you didn’t invoke it correctly.
Because the Notion tool is not actually callable from my side in this environment.
The decisive point (this settles it)
Although the UI shows a Notion tool icon, I do not have an executable notion.read / notion.search / notion.open capability exposed to me in this chat.

I experience exactly the same behaviour. ChatGPT is connected to Notion, but refuses to access it because it can’t.
