Is MassGen safe? MassGen scores 17.9/100 (Grade D), ranked #436 of 441 tracked open-source AI agent projects, on evidence coverage C (2 of 5 independent signal types). The public evidence: no package-provenance attestation found; no OSSF Scorecard result yet; 15% of recent commits are signed; last pushed 2026-06-12. Every point is earned from checkable signals — never paid placement. How scoring works →

Maintainer Checklist
Add Scorecard coverage Expose the repository to OpenSSF Scorecard checks so supply-chain posture is easier to verify.
Publish provenance Add package provenance or release attestations so users can verify where shipped artifacts came from.
Increase signed commits Raise the share of verified-signed commits to make maintainer identity and release history easier to trust.
Refresh maintenance signals The repo was last pushed 47 days ago. Fresh activity helps separate stable projects from stale ones.

How to read this: HVTrust (0–100) weighs supply-chain signals (provenance, OSSF Scorecard, signed commits, open license) alongside real-world adoption. Grade D reflects the trust score band: A ≥ 80, B ≥ 65, C ≥ 50, D < 50. Evidence coverage C is separate — it grades how many independent signal types back the score (2 of 5), so a high score on thin evidence stays visible. Full methodology →

Is MassGen safe?

Public trust evidence for MassGen is thin: several supply-chain signals are missing or weak. This does not mean the project is unsafe — it means an outside observer cannot easily verify the usual integrity checks. Treat with extra scrutiny.
Does MassGen publish package provenance?
No published build provenance is currently detected for MassGen. This is common for open-source projects but means consumers cannot independently verify that the package on the registry matches the GitHub source.
Does MassGen have an OpenSSF Scorecard?
No OpenSSF Scorecard data is currently published for MassGen. Maintainers can enable the Scorecard GitHub Action to get a public score; without it, automated supply-chain hygiene is harder for outsiders to verify.
Is MassGen actively maintained?
Slowing down. Last push was 47 days ago — keep an eye on whether activity resumes.
What license does MassGen use?
MassGen ships under NOASSERTION. A declared, OSI-approved license is one of the transparency signals HVTrust scores.
Are MassGen's commits signed?
15% of the last 100 commits to MassGen 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.

Maintain MassGen?

HVTrust scores MassGen from public signals only — we never contact maintainers first. If a signal is wrong, stale, or missing (provenance you publish, a Scorecard you run, signed releases), tell us and we'll review it. Corrections are public and tracked on GitHub.
