NotebookLM MCP Structured: Free Server Connects Claude to NotebookLM with Automatic Prompt Structuring
NotebookLM MCP Structured is a free MCP server that connects Claude Desktop (or any MCP client) to NotebookLM notebooks. It automatically structures prompts and controls how Claude handles NotebookLM responses.
What it does
The server sends questions to NotebookLM, gets answers, and passes them back to Claude. The key difference from the original notebooklm-mcp fork by Gérôme Dexheimer is the prompt structuring system that operates in both directions.
Key features
- Automatic prompt structuring: Detects query type (comparison, list, analysis, explanation, or extraction) and builds structured prompts adapted to that type
- Completeness check: Claude can autonomously make 2-3 additional queries to NotebookLM if answers seem incomplete
- Fidelity constraint: Prevents Claude from adding information not grounded in notebook documents while allowing synthesis and reorganization
- Multilingual support: Handles queries in any language without translation layers
- Simplified authentication: Uses Patchright (a Playwright fork) for cleaner browser session handling
Architecture
The structuring logic lives in the MCP tool description for ask_question. This is a deliberate architectural choice where instructions are defined server-side but executed client-side by Claude. This approach reduced code significantly compared to the original.
Development and documentation
The entire development was done through vibe coding with Claude Code (Opus 4.6), with no manual coding. The manual was written using Claude's Cowork mode and includes 11 chapters covering installation, configuration, how the structuring system works, and troubleshooting.
Practical differences from original
- Simplified authentication that doesn't require closing Chrome instances
- Smaller, more readable codebase
- Comprehensive manual aimed at non-developers
The server is available on GitHub and includes a complete manual with PDF download option.
