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 Growthbook MCP

Public supply-chain signals for Growthbook MCP are strong: it has multiple independent trust indicators in place. This does not replace your own security review, but Growthbook MCP carries less obvious unverified-evidence risk than projects with thin signals.
Does Growthbook MCP publish package provenance?
Yes. Growthbook MCP's package releases carry build provenance attestations, which cryptographically link the published package back to its source repository and CI workflow.
Does Growthbook MCP have an OpenSSF Scorecard?
Growthbook MCP has an OpenSSF Scorecard score of 5.1/10. 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 Growthbook MCP actively maintained?
Actively maintained. The repository was pushed to within the last 1 day(s).
What license does Growthbook MCP use?
Growthbook MCP ships under MIT. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are Growthbook MCP's commits signed?
25% of the last 100 commits to Growthbook 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.
