What the numbers say

  • Developers build on NotebookLM without an official consumer API: 760 repositories carry the notebooklm topic, and 8,895 use the name.
  • MCP servers were the 2026 wave: repositories named “notebooklm” and “mcp” peaked at 29 in February.
  • Activity fell after July. The rename and the September 2 usage limits came in the same months, so the numbers can't separate the two.

How these numbers were made

  • Repositories: GitHub repository search by name and creation date, run on October 17, 2026. Deleted and private repositories aren't counted.
  • Downloads: npm's download API and pypistats.org (without mirrors). Downloads include automated installs, so read them as activity, not people.
