Google just opened up Gemini Notebook to developers, and it ships with an MCP server. The short version: you can now create notebooks and push sources into them from your own code or straight from Claude Code, no clicking around the UI. - REST API plus a remote MCP server, both in Public Preview - 7 MCP tools: create, get, list and update notebooks, plus create, get and list sources - Sources: web pages, YouTube videos, plain text and Markdown - Setup docs for Claude Code and Cursor, and it works with any Streamable HTTP MCP client - Free during the preview, with a limit of 20 new sources per minute per user - Up to 500,000 words per source, 50 sources per notebook on the free tier - Personal Google accounts only for now, Workspace accounts aren't supported yet - Pre-GA, so expect breaking changes The use case I keep coming back to: an agent that watches a client's site, YouTube channel or docs and keeps a research notebook current without anyone touching it. What would you pipe into a notebook automatically if you could? Drop your idea below. Read more: https://developers.google.com/notebook/docs
