Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01415 | $0.01415 |
| Opus 5 | $0.00707 | $0.00707 |
| Sonnet 5 | $0.00283 | $0.00283 |
| Haiku 4.5 | $0.00142 | $0.00142 |
Grade A, and why
notebooklm-mcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Commands
# Install dependencies (pnpm pinned via packageManager field)
corepack enable
pnpm install
# Build (outputs to dist/)
pnpm run build
# Watch mode for development
pnpm run dev
# Run the built CLI directly
node dist/cli.js serve
node dist/cli.js auth
# Run the test suite (vitest + MSW)
pnpm test
# Release flow
make release # local bump + tag
make release-push # supply-chain audit then push (publishes via CI on tag)
make pre-release # standalone audit
TypeScript strict mode is the primary quality gate — fix all type errors before building. CI runs pnpm test before publishing to NPM.
Architecture
This is an MCP (Model Context Protocol) server that bridges AI assistants to Google NotebookLM's internal batchexecute RPC API.

src/tools/*.ts |
Tool implementations grouped by domain (notebook, source, studio, query, research, auth) |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

notebooklm-mcp CLAUDE.md is an instructions file published in the GitHub repository m4yk3ldev/notebooklm-mcp (18 stars, last pushed 1mo ago), licensed MIT. It adds 1,415 tokens to every session, about $0.0071 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
