FAQ from Notion MCP

How do I get a Notion API key?

Go to the Notion Developer Page, create a new integration, and copy the “Internal Integration Token”.

How do I find the Page ID?

Open the target page in Notion, look at the URL (a 32‑character string separated by hyphens), or click “Share” → “Copy link” and extract the ID.

How do I set integration permissions?

On the Notion page, click “…” → “Connections” (or “Add connections”), then search for and add your integration.

What does the command node index.js "[date]" "content" do?

It accesses the Notion page, finds the 2025 subpage and the March subpage, creates the specified date block and content block there. If a block with the same date already exists, it does not create a duplicate.

What happens if a block with the same date already exists?

The application will not create a new block; it simply skips that step and continues without error.
