Research a question against exactly one NotebookLM notebook. Returns a compact source-locked evidence capsule with claims, citations, conflicts, gaps and quality status. Use this for substantive notebook questions.

List the authenticated account’s live NotebookLM notebooks. Use this when the user asks what expert notebooks are available; the result includes an explicit count and cached results are marked catalog_stale when live discovery is unavailable.

List authoritative remote source IDs and titles for one NotebookLM notebook using the RPC-only metadata path. Use before discussing corpus scope or freshness.

Check Frontier, persistent NotebookLM authentication, and upstream transport readiness without exposing credentials.

Resolve a notebook by title, alias, ID or URL. Cache misses trigger a live refresh; cache is never authoritative.

Force refresh of live notebooks and sources, detecting created, renamed, deleted and newly added items.

Retrieve one evidence item by evidence ID from a previous research session.

Explicitly compare two notebooks while preserving provenance by notebook. Never invoked implicitly.

Open a visible Chrome window for secure Google login. Set force=true when cookies look valid locally but Google redirects to sign-in.

Run local diagnostics for runtime, adapter, registry and stdio-safe MCP operation.
