In MCP Servers

How to read this: HVTrust (0–100) weighs supply-chain signals (provenance, OSSF Scorecard, signed commits, open license) alongside real-world adoption. Grade B reflects the trust score band: A ≥ 80, B ≥ 65, C ≥ 50, D < 50. Evidence coverage B is separate — it grades how many independent signal types back the score (3 of 5), so a high score on thin evidence stays visible. Full methodology →

Common questions about NotebookLM MCP

NotebookLM MCP has a mixed signal profile. Some trust indicators are present, others are missing. Whether it is safe for your use case depends on which gaps matter to you — review the breakdown below before adopting in production.

Does NotebookLM MCP publish package provenance?

Yes. NotebookLM MCP's package releases carry build provenance attestations, which cryptographically link the published package back to its source repository and CI workflow.

Does NotebookLM MCP have an OpenSSF Scorecard?

NotebookLM MCP has an OpenSSF Scorecard score of 3.8/10. The Scorecard checks for branch protection, signed releases, dependency updates, fuzzing, code review, and other supply-chain hygiene items. See the full check breakdown on this page.

Is NotebookLM MCP actively maintained?

Maintained. Last push was 22 days ago.

What license does NotebookLM MCP use?

NotebookLM MCP ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.

Are NotebookLM MCP's commits signed?

6% of the last 100 commits to NotebookLM MCP are verified-signed (GPG, SSH, S/MIME, or GitHub's signing flow). Signed commits help confirm that code was authored by who the commit claims.

Not a safety endorsement. HVTracker describes what public signals show, not whether a project is safe for your use case. Run your own security review before adopting in production.
